Publisher’s

note

Danish Blue DON’T WORRY, THIS PUBLISHER’S NOTE IS NOT ABOUT THE STRONG, BLUE-VEINED CHEESE FROM DENMARK. NEITHER IS IT ABOUT THE DANISH ‘BIG BLUE’ MAERSK LINE. IT’S ABOUT THE IMPACT OF BLUE DENMARK – THE DANISH MARITIME cluster of international shipbuilding, ship design and naval architecture. The maritime industry is the second largest industry in Denmark based on currency earnings. The industry offers solutions customised to specific requirements and has become famous for quality products and innovative technology. The country is a driving force for the industry, being home to some very large shipping companies and some top-class naval architects and suppliers.

Denmark’s influence on the international shipbuilding industry is made plentifully clear in this issue: OSK ShipTech have designed a vessel to operate the EU’s first ever domestic ferry route powered

by LNG (pg 38). Knud E Hansen won this year’s ShipPax award at the 12th Annual Ferry Shipping Conference with the design of RoRo vessel Bahri Abha (pg 44). The vessel is notable for her fast and flexible loading and unloading capabilities. Both ship designs demonstrate a progressive approach that hints at the future of European shipbuilding.

Speaking of the future, Denmark has been outspoken in its promotion of reduced NOX emission regulations in the North and Baltic seas by 2016. One of the world’s largest shipping companies, Maersk Line, has been trialling NOX reduction technology on board two of its vessels (pg 34). We also look at the building of a fishing vessel at Karstensens (pg 14) that combines centuries of local industrial experience with the most up-to-the-minute propulsion technology for efficient, environmentally friendly performance.

DENNIS VINKOERT | PUBLISHER & EXECUTIVE EDITOR DENNIS@YNFPUBLISHERS.COM

Last but not least, in October Denmark will host a major new event for the global maritime industry – Danish Maritime Fair which goes along with the Danish Maritime Days. It will bring together a broad spectrum of leaders from across the industry with the objective to find new solutions to the most important challenges facing the industry today and in the future. And just to stick to the colour as mentioned in the headline: A Blue Innovation Camp will be an integrated part of the event providing the opportunity to see live innovation.

Enjoy the issue!

NEWS IN BRIEF SBI FEATURE

DBR Generatorsets Wins Large Repeat Order DBR will supply emergency/harbour diesel generator sets for six new pipelaying vessels under construction at IHC Merwede for Subsea 7 and SapuraKencana. The order for the custom engineered units, generating up to 1,875kVA, follows DBR’s successful delivery of three similar generator sets for IHC Merwede in 2013. For each of the six new generator sets,

DBR selected Mitsubishi diesel engines and either 800kVA Leroy Somer or 1,875kVA AvK generators. The first of the six new generator sets was successfully FAT tested at DBR’s test bench and already delivered earlier in 2014. The delivery of the next custom built units will continue on-going in 2014 and 2015.

Emigreen’s New Generation Emigreen recently introduced a solution designed to control diesel engine exhaust emissions, the Emigreen Alpha-Alpha soot filter system. The innovative system reduces soot, hydrocarbon and noise emissions continuously monitors system performance and, if required, raises the temperature of the exhaust gas to incinerate any build-up of carbon deposits. The result: reduced emissions and a long service life under all engine loads. Additional operational benefits are high efficiency, a virtually odourless exhaust and compatibility with all marine distillate fuels, serviceability and durability. When retrofitted, the Alpha-Alpha replaces the original silencer.

Strong Tensile Strength

18,000 hours’ Work on the Étoile

DSR Corp, the Korean shipbuilding and offshore rope maker, recently launched its innovative fibre rope, SuperMax78. The special fibre rope of Ultra-highmolecular-weight polyethylene (UHMWPE) has stronger tensile strength and weighs less than an eighth of steel wire ropes of the same diameter.

SuperMax78 is specially designed so that its life span and performance is not affected by a wide range of weather conditions. Recently, DSR was awarded a significant offshore project in Brazil where they provided 3,300t Minimum Breaking Load slings.

After almost 6 months in the shipyard, the sail-training vessel belonging to the French Navy, schooner Étoile went back in the water. It has been Étoile’s biggest refit for 40 years. Guip Shipyard relaid her working and quarterdecks with Oregon pine, replaced some of her oak deck beams and gunwales, and built a new chart room for the navigation students.

Oregon pine was also used to replace the old topmast.

Her hull was thoroughly checked and some of her fastenings strengthened. Shipboard electronics were brought up to date by Guip while Navtis, joint contractor for the works, completely rebuilt the electrical system.

Haifa Port Orders Tug

Prototype with Suspension System

Zamakona Yards has signed a contract with Haifa Port Authority for the construction of ‘Haifa’, a Voith Schneider tug boat, to aid in port operations. The new building will be powered by two MAN 8L27/38 engines with delivery set for August 2015. Haifa will be a sister to the ‘Ilan I’, which began towing and general harbour operations at Haifa Port in 2012. With a length of 31.5m and a 12.5m beam, the new vessel’s Voith Design hull will have a bollard pull of 70t. It will be equipped with a minimum of two monitors, each able to discharge 1,500 m3 per hour at a pressure of 14 bar, and will be classified by Lloyd’s Register with FiFi 1 notation.

Research and development company Nauti-Craft Pty has released previously confidential details, images and video of their latest prototype vessel ‘2Play’. Their latest prototype is an 8m catamaran, the first of its kind. At its core is the Nauti-Craft marine suspension system. This technology separates the vessel’s hulls from the deck and superstructure via a ‘passive reactive’ interlinked hydraulic system that provides unsurpassed levels of control and stability whether stationary or travelling at speed. 2Play has recently successfully completed extensive sea-trials in the waters and had its public debut at Seawork 2014.

NEWS IN BRIEF Underwater Welding Repairs

LNG-Powered RoRo Ferry from FSG

UPE recently performed a rudder inspection by using class certified NDT procedures. During the inspection it was shown that a weld seam of approximately 27m was corroded to the point that there was complete penetration and the rudder was partially flooded. The vessel had still two more years to go before dry docking, and her tight operation schedule left no room for off hire. A specialised repair plan was made in alliance with the classification society and in less than 50 hours the rudder was completely repaired by the grinding away of all corroded areas and re-welding of new seams. The rudder was filled back with air and all seams tested positive by certified MPI equipment.

Flensburger-Schiffbau-Gesellschaft (FSG) has chalked up yet another global sales success by signing a contract with the Australian shipping company SeaRoad for a 181m RoRo ferry new build. What is special about this ship, however, is that it will be the first of its kind for FSG to be powered by eco-friendly LNG rather than by diesel or heavy oil. FSG and SeaRoad have been working intensively over the past years on this project, which successfully moved into a new phase with the signing of this contract.

Efficient & Safe Classification Process

Nordic Yards Takes Over Volkswerft

SEA Europe and the European Recognised Organisations (ROs) have held a workshop on the Mutual Recognition of Classification Certificates. The aim was to develop understanding amongst maritime classification stakeholders. Discussions were held on competitive advantage, cooperation of industry in technical development, global acceptance of Mutual Recognition and the way forward.

Douwe Cunningham, SEA Europe Secretary General, reported a positive atmosphere and said there were signs of trust being built between the industry and EU ROs. “Going forward we, as European technology manufacturers, have to assess if the ultimate goal of the industry, of relocating administrative burden, can be realised. This is the prime motivation of the industry for pursuing the Mutual Recognition of certificates.”

At Volkswerft Stralsund, Berthold Brinkmann, insolvency administrator P+S Werften, handed over a big key to Nordic Yards. With that, Nordic Yards has now officially taken over Volkswerft.

“Volkswerft is one of the most diverse shipyards in the Baltic Sea region, and has excellent suitability both for the construction of ships and complex offshore structures and for the overhaul and repair of civil and military ships,” said Berthold Brinkmann. By the end of 2016, 500 employees should be working at the shipyard.

SHIP REPORT

Position Strengthened Ceona Amazon Ceona Amazon was launched on 25 April in a ceremony overseen by Ceona COO Stuart Cameron at the Crist shipyard in Gydnia, Poland.

After delivery the hull was towed to Lloyd Werft in Bremerhaven, Germany for final outfitting.

Ceona Amazon’s design is based upon a DP2 drill ship. She is particularly suited to operations in remote and challenging waters and is able to lay flexible and rigid pipes and supply lines to depths up to 3,000m.

1 2 | S B I 2 0 1 4 | Vo l um e 8 | Issue 3

Polar Onyx.indd 12

Construction of the vessel was carried out by Ulstein Verft in Norway and she features an Ulstein X-bow hull. The vessel was delivered to owners GC Rieber Shipping. Speaking at the time of the delivery, CEO of the Ulstein Group Gunvar Ulstein said, “Ulstein has a complete cycle of expertise in ship design, engineering, shipbuilding and ship investments, specialising in high-quality, advanced offshore vessels for demanding operations worldwide. We have had an excellent cooperation with GC Rieber in the development and construction process and we wish the ship owner and contractors all success with the Polar Onyx.”

Irene W. Basili, CEO of GC Rieber Shipping, said that the new vessel would help the company to develop its subsea capabilities further. “The new addition to the company is a vessel with high technical and operational capacity which will strengthen our position in the high-end subsea segment. The vessel is designed to meet the increasing expectations from our clients in this

segment in terms of operational redundancy and flexibility.”

Good Seakeeping The Polar Onyx is based on Ulstein’s SX121 design for operations in the SURF, construction and IRM markets and, specifically, in harsh conditions and deep water. She is 130m in length with a beam of 25m. Her Ulstein bow ensures she can maintain a good pace, at speeds up to 15 knots even in rough seas, without burning excess fuel – good news for both transit time and the environment.

Environmental considerations are a key part of Ulstein’s design. The Polar Onyx, which carries a Green Passport, complied with all the latest environmental regulations and is certified to Special Purpose Ship and Clean Design.

The vessel is powered by a diesel electric plant featuring six identical 2,740ekW generator sets for total installed power of 16,440kW. A steady course is ensured by a set of six thrusters – three fore and three, azimuthing, aft, totalling 15,280kW – essential for effective pipe-laying duties.

SHIP REPORT

Polar Onyx seen prior to her pipelay tower being installed.

Getting Ready to Go Huisman carried out the final outfitting of the vessel at their yard in Schiedam, the Netherlands.

This involved installing a 275t vertical lay system (VLS) and a deck mounted carousel with 200t flexible product capacity.

Also in Schiedam, two ROVOP hydraulic, work class ROV systems were mobilised to the Polar Onyx.

Ceona awarded ROVOP with a 5-year contract for the provision of the systems. The technologically advanced systems include a modular design that improves repair and maintenance times. Also featured are a range of auto-pilot functions for improved safety and efficiency. The ROVs, as well as the VLS, enable the vessel to perform installation at depths of up to 3,000m. Ulstein have installed two moon pools, one 8 x 8m for the VLS and another, 4.9 x 4.9m for one of the ROVs. The other ROV is deployed over the starboard side of the vessel.

ROVOP Managing Director Steven Gray said, “The long-term commitment agreed between Ceona and ROVOP reflects the shared vision of using advanced technology and personnel with decades

www. s h i p b u i l d i n g - i n d ustr y.eu

Polar Onyx.indd 13

of experience to challenge conventional thinking.

This brings safer, more efficient and reliable services to the subsea construction market.”

High Standards Polar Onyx has the highest standard in dynamic positioning, DP3, with additional redundancy for all major onboard components. Operability in DP2 mode is maximised due to an Operation+ feature, which enables continued operations even after a substantial single system failure.

Polar Onyx has two cranes, an offshore active heave compensated (AHC) crane that can lift 250t at an outreach of 14m and 12t AHC crane. Her large deck area of 1,700m2 offers storage capacity for up to 5,800t.

Ulstein’s design provides the vessel with the capacity, weather and tide dependent, to remain at sea for up to 80 days. Whilst onboard accommodation for 130 people ensures she can be sufficiently manned during this period. i. www.ceona-offshore.com

NAVAL ARCHITECTURE & DESIGN

BUILDING A MODERN PELAGIC FISHING TRAWLER

Green

Powered Design ALMOST A CENTURY OF DANISH FISHING VESSEL DESIGN COMBINED WITH THE MOST UP-TO-DATE HYBRID PROPULSION SYSTEM HAS RESULTED IN THE HERØYHAV – A FLEXIBLE, ECONOMIC AND ENVIRONMENTALLY FRIENDLY FISHING trawler bound for the Norwegian coast. Editor Tom Scott contacted Karstensens Shipyard Director and Naval Architect Kent Damgaard to discover that, due to changing fishing policies and practices, fishing vessel design is a dynamic, constantly evolving process.

I

n recent years, Karstensens Shipyard, on the northern tip of Denmark, has entered a new market in building vessels for the Danish navy.

Traditionally, however, their main activity has been new building of fishing vessels – namely pelagic and whitefish trawlers. The yard has launched more than 400 vessels in the course of its 97-year history. One of the most recent was hull number 423 – the Herøyhav – a pelagic trawler and purseseiner constructed for a Norwegian fishing company of the same name.

First For Design

Karstensens has a rich history building pelagic trawlers: “Every design is unique and tailor-made to customers’ specifications and requirements,” explains Karstensens Shipyard Director and Naval Architect Kent Damgaard. “The 69.95m Herøyhav, 1 4 | S B I 2 0 1 4 | Vo l um e 8 | Issue 3

Quota Policies

The final design is specifically related to the available fishing quota of the vessel owner.

“With this size class of fishing vessels, the quotas are often distributed between Barents Sea, North Atlantic and North Sea,” continues Mr Damgaard. With her bunker capacity of 500m3, the Herøyhav has the ability to stay out at sea for around 45 days.

“In reality these vessels are seldom at sea for more than 14 days. More often the trips are very short, even as short as 2 days.”

Another factor that determines the final design is the country of ownership and, consequently, that country’s fishing management policies. “There is a considerable difference between the quota-

management policies of North European countries,” informs Mr Damgaard. “In Denmark, in particular, the fleet has been dramatically reduced, which has led to the ordering and building of even larger vessels.

In Norway, where Herøyhav is registered, such a congestion has yet to be seen.

Norwegian fishing vessel design is more like an evolution of the existing fleet.”

the ECO Speed Pilot for optimal voyage planning and speed setting. In terms of footprint, the addition of a hybrid propulsion has design implications. “The only physical design difference between this hybrid propulsion and a conventional dieselmechanical system is a frequency converter,” adds Mr Damgaard.

Hybrid Flexibility

Hybrid propulsion systems are a combination of electric propulsion and diesel drive, and enable ships with variable power requirements to run at high propeller efficiency. The hybrid configuration of the propulsion package combines fuel efficiency and flexibility with high redundancy. The Herøyhav has a large number of operational modes at her disposal, enabling the engine and propeller to run optimally over a wider power range.

The various power modes utilise dieselmechanical, diesel-electrical and hybrid combinations. The auxiliary generators can

As well as the overall design, what stands out on the Herøyhav is the flexible and environmentally friendly propulsion set-up that offers a number of fuel-saving power modes to accommodate the different fishing patterns it will encounter at sea. The hybrid propulsion package consists of a MAN 9L27/38 engine and a two-speed reduction gear that drives a MAN Alpha 4,200mmØ ducted propeller. The propeller nozzle is a customised MAN Alpha AHT design. MAN Diesel & Turbo also supplied its Alphatronic 2000 propulsion control system, including

Green Features

The Herøyhav verified the following ship speed/ power modes during sea trials: • 11.6 knots – 1,400 kW (diesel-electric, variable propeller speed) • 14.0 knots – 2,400 kW (diesel-electric, fixed propeller speed) • 15.5 knots – 3,285 kW (diesel-mechanical) • 16.6 Knots – 4,785 kW (diesel-mechanical + electric boost)

deliver 1,500kW auxiliary power to the hybrid system, which – in combination with the main-engine power of 3,285kW – offer a total propulsion output of 4,785kW for trawling or full-speed steaming.

As a result of the fuel-saving propulsion setups for the various operational modes, the Herøyhav limits exhaust gas emissions.

The environmentally friendly features do not stop there – the coated propeller shaft, installed in combination with a waterlubricated stern-tube system, eliminates any risk of sealing damage and any leakages of stern-tube oil to the sea in the event of impact with fishing gear wires. i. www.karstensens.dk

NEW GENERATION OBLIQUE HULL FOR WIDER ICE CHANNELS

Breaking the Ice SOMETIMES A SINGLE ICEBREAKER IS INSUFFICIENT TO CLEAR A CHANNEL FOR LARGE VESSELS. USING TWO VESSELS IN TANDEM IS INEFFICIENT HOWEVER AND FOR YEARS ATTEMPTS HAVE BEEN made to find a solution. The answer to the problem is Baltika. Hailed as the most advanced and innovative icebreaking vessel, her oblique hull was developed exclusively for Arctech Helsinki Shipyards by Aker Arctic Technology.

WORDS BY BEN LITTLER

After many years of development work, the oblique icebreaker concept represents a breakthrough approach.

he idea was first pioneered in the 1990s as a solution to the use of two conventional ice breakers to escort large tankers through the icy waters of the Baltic in winter. Aker developed a patented vessel design concept known as ARC 100. They proposed a triangular vessel with an azimuth thruster at each point.

The plan was that the vessel would approach ice at a 50° angle, opening a 50m channel, large enough for vessels of 40m beam. In November 2011, the first vessel featuring the hull design was ordered by the Russian Ministry of Transport in a deal worth in the region of EUR 76 million.

Ice & Fire The hull blocks were constructed at Yantar Shipyards in Kaliningrad, Russia and then transported to Arctech in Helsinki for outfitting, finalising, optimisation and commissioning.

Yantar is a part of the United Shipbuilding Corporation (JSC).

Arctech is a joint-owned venture between JSC and STX Finland.

The result, the NB 508 Baltika, is a multi-purpose icebreaker that can be used to break ice in harbours and adjacent waters, to tow distressed vessels to secure locations and to perform sea towing of vessels and floating structures. Arctech have built a vessel that can also be used in

rescue operations, oil spill response, external fire extinguishing, environmental monitoring and salvage and rescue operations.

Baltika has a workboat for oil boom handling, a 25t knuckle boom offshore crane for workboat handling, load movement and oil spill response functionality and helideck suited to Ka32 helicopters.

Innovation in Her DNA Aker tested the hull form and established that it could proceed through 1m thick level ice both ahead and astern. Obliquely she can proceed in 60cm level ice. Baltika is 76.4m in length with a beam of 20.5m and a 6.3m draught.

Esko Mustamäki, Managing Director of Arctech Helsinki Shipyard, said, “There is demand for innovative icebreaking vessels in the Russian market. This rescue vessel represents a totally new technology, which enables its versatile use in the Gulf of Finland and it is designed in accordance with the highest international and Russian requirements and standards.”

The vessel is powered by a dieselelectric system, featuring three Wärtsilä 9L26 engines, suited to low sulphur fuel oil usage and with a total power of 9MW, three Steerprop pulling azimuth thrusters and the Metso DNA automation system.

system which covers the machinery, alarms and monitoring, controller loops and tank monitoring as well as the pumps, valves and electric power management system. The process controllers are redundant with main and reserve units in different locations to secure maximum system availability.

DNA features an extensive range of analytical and reporting tools to optimise machinery performance and reduce fuel consumption.

Slick Operator The oil spill response (OSR) capabilities of Baltika are advanced. She has an oil recovery system from Finnish company Lamor Corporation that can be employed even in heavy seas. The vertical side of the hull is used as a sweep arm and, as the vessel moves obliquely through an oil slick, contaminated water is guided through a hatch in the hull to a skimmer tank. Inside the skimmer tank a series of built-in brush collectors separate the oil from the water. The oil recovery sweeping width has a reach of 50m.

Mikko Niini, Managing Director of Aker Arctic Technologies, said, “Oil combat in ice conditions is one of the major challenges for the international oil industry. After many years of development work, the oblique icebreaker concept represents a breakthrough approach for the solution… Drilling permits in the Arctic region will only be granted if multipurpose OSR equipped vessels and actionable contingency plans are in place to ensure rapid mobilisation and response to any incident.”

Autopilot Engaged Baltika’s DP and autopilot systems are from Navis.

This has been a challenging project, Navis report, due to the vessel’s unique shape. Preliminary trials highlighted the importance of these features to the control of such a vessel. The DP system, NAV DP4000, can be set to automatic and semiautomatic modes with speed and drift angle predetermined. DP algorithms take into account the need to minimise the impact of the hull’s asymmetry.

Sea trials confirmed the DP control and heading control systems met their declared performance of being accurate at 6 Beaufort sea state and winds of 14m/s to a positioning accuracy of 1m and a heading accuracy of 1 degree.

The Navis AP4000 Heading control system is an upgrade on the AP3000 and, Navis report, is part of a new generation of autopilots, representing modern, technologically advanced, digital solutions. Navis has designed the autopilot to reduce operator workload, increase motion efficiency and improve operational safety.

Amongst the upgrades Navis made to the AP system are an improved screen view with day and night setting and increased front panel protection.

This means that the AP can now be installed outside, on the fly bridge or the port or starboard wings. i. www.arctech.fi

einzmann have 20 years of experience in electronic fuel injection. As well as developing and producing components they offer complete rail systems and related services on engines ranging in size from 500-10,000kW. Their challenge in this case was to retrofit a common rail system to an ice breaker with five 40-year-old 2.2 Pielstick engines, ensuring compliance with current and future regulations as well as delivering considerable savings on fuel costs.

The vessel in question is operated by the Swedish Marine Administration in the Baltic Sea. Depending on the output required, between one and five engines are used at any one time.

Well Suited

Typically for a vessel such as this, work often involves ‘push-pull’ operations; fast and frequent load changes that equal high consumption of fuel and emissions in excess of those expected in modern maritime procedures.

Heinzmann say that such vessels will benefit from retrofitted advanced electronic fuel injection technology.

Heinzmann opted to convert just one of the five engines to begin with, in December last year. The work, which did not involve major modifications to the engine, was carried out in Lulea, Sweden in close cooperation with the engine manufacturer.

Converting a single engine

as a starting point allowed for comparisons to be made with the other, nonconverted, engines in terms of performance, fuel economy and emissions.

Tests were carried out during the vessel’s usual operations commencing in January.

Administration will also be converted the following year. Additionally, two similar conversions are to be carried out on Finnish ice breakers.

Heinzmann say that, based on assumed operations in advance of 5,000 hours per annum, associated fuel

lowest fuel consumption, in diesel and gas operation.

The improvements can be furthered with combustion optimisation and modification of the combustion chamber and injection spray patterns.

Heinzmann’s customer tailored solution is available

Good Results

Heinzmann have reported that all tests met the expectations of the customer. Transient behaviour improved in comparison to the original hydraulic governor, they say and particle emission has completely disappeared.

Crucially, fuel consumption was considerably reduced, offering savings in excess of 6 percent compared to preconversion rates.

Furthermore, as a result of cylinder to cylinder balancing and the applied injection profile the engine runs very smoothly, Heinzmann report. This, they say, will have a positive effect on the service costs and the life-span of the engine.

As was anticipated, the conversion does not impact on the vessel’s NOx values.

However, with the addition of an optional exhaust gas recirculation system, compliance with IMO Tier 2 regulations is anticipated without aftertreatment.

Quick Return

Because of the positive results, conversion of the remaining four engines is now due to be carried out in time for the coming winter.

DAMEN UNVEILS NEW BALLAST WATER TREATMENT SYSTEM

Self Contained AT THIS YEAR’S POSIDONIA EVENT IN ATHENS, GREECE, DAMEN UNVEILED THEIR NEW, MOBILE AND FULLY CONTAINERISED BALLAST WATER TREATMENT SYSTEM – InvaSave. An alternative to the costly retrofitting of a fixed system, InvaSave is a further boost for Damen’s Ballast Water Centre of Excellence.

WORDS BY BEN LITTLER

T

he requirement of the Ballast Water Management Convention (BWMC), as well as additional localised regulations, to treat ballast water before discharge has, up to now, meant investing in a fully fixed system, often fitted retrospectively. For some ship owners this is not an ideal scenario – in particular those with ageing vessels that are not liable to be operating long enough for a return on investment and those that discharge ballast water only infrequently.

Containerised Solution

Step forward Damen with an innovative solution to the problem – and one that carries with it a number of additional benefits to boot. The entire InvaSave system sits within a single container 12.2 x 2.45 x 2.75m in dimension. Internally the container is broken into two parts – one housing the independent power supply and the other handling treatment and control.

Each container handles 300m3/h of water. If

additional capacity is required then it can be reached simply by application of further containers. The system is based upon continuous fine filtration combined with UV treatment and requires no chemicals to function. Sludge and sediment is dewatered and compacted in order to receive further processing once safely onshore.

Fringe Benefits

The cost-efficiency of the system is of course, the primary benefit, as Gert Jan Oude Egberink, Damen Manager Ballast Water Treatment, states, “We have been looking into what we can do to help our customers regarding ballast water treatment and finding alternatives for those owners that may not want to retrofit a ballast water treatment system, perhaps because their ships operate on fixed routes or their ships

This is all in-house technology and is very simple to use.

are too old and make the investment in a system prohibitively expensive.”

But, he points out, there are others pros that may outweigh installation of a fixed system, explaining that InvaSave can also offer contingency at ports. “Ports may also need to provide back-up, in case a ship’s onboard treatment system fails.”

Upwardly Mobile

The portability of the system comes into its own in such a scenario. Its mobile nature means that Damen can deliver the container direct to a vessel, or to a port where it can be easily mobilised with a trailer, pontoon or, in the near future, a specialised Damen Ballast Water Treatment Vessel.

This is only the beginning, however and there are a number of other advantages, not least of which is the fact that no vessel downtime is required for a lengthy installation process, or indeed for ongoing maintenance. Additionally, in contrast to fixed systems, the ballast water only requires treatment at the point of discharge and not at the point of intake.

And then there’s the simple fact that the Damen system offers genuine ease of use, as Mr Oude Egberink continues: “This is all www. s h i p b u i l d i n g - i n d ustr y.eu

in-house technology and is very simple to use – essentially it is a plug & play system in one container. Vessels only need to have a deck connection. Using this mobile treatment unit, owners and operators will be fully compliant with both the IMO and US regulations.”

Ballast Water Treatment Vessels

High Standards

The water treated by the system meets the standards specified in the IMO BWMC regulation D-2, at the very minimum.

InvaSave additionally meets the highest noise level standards.

InvaSave has been extensively tested in a range of conditions in the Dutch waters of the Waddenzee and the Ijsselmeer. What this demonstrates is the system’s versatility and capacity to operate effectively, not just in salt water, but also in fresh and brackish water.

The new system is currently undergoing IMO type approval testing, which will continue throughout the year. It is anticipated that this will be received at the start of 2015.

InvaSave is being certified by the Dutch Flag State and has a patent pending.

These unique vessels have been designed by Damen to operate in ports, supporting ships’ deballasting operations. An important financial partner in this is the Waddenfonds, an organisation responsible for conservation activities in the UNESCO world heritage site the Waddenzee. The first barge of this kind is already under construction and will, when ready, be used for operations in Eemshaven and Delfzijl, the Netherlands.

olls-Royce and Island Offshore have cooperated closely in the design of the vessel, which, according to Island Offshore CEO Håvard Ulstein, will be a “game changer.” The vessel is specially prepared to provide offshore drilling services, even in the harshest of conditions. Amongst her repertoire, the vessel will have the capacity to perform top hole drilling, subsea construction and inspection and repair and maintenance work in deep water. With adaptation she will also be capable of light well intervention duties.

Safe Speed

Island Offshore identified a number of benefits associated with using a monohull vessel for this scope of work, as opposed to an anchored rig. Such a ship offers lower day rates, faster transit, no requirement for a AHTS vessel and no need for lifting to take www. s h i p b u i l d i n g - i n d ustr y.eu

place between a supply vessel and rig in heavy seas.

Plus, with the DP3 system, not only is the need for anchoring removed, safety is also increased. In the event of a shallow gas event, the vessel is able to make a hasty exit from the scene.

A feature of the design is an enclosed module handling tower, providing a secure, comfortable working environment.

Rolls-Royce are also supplying the vessel with major systems, including the propulsion system with six generator sets and seven electric thrusters, control and automation systems, mooring and anchoring deck machinery and electric systems.

ABB are supplying a completed diesel and electric system for the vessel, including switchboards, medium voltage generators, transformers and motors.

John Knusden, Rolls-Royce President Offshore said, “This new design is based on many years of operating experience, especially from the vessel Island Wellserver, which we designed in 2005. The UT 777 will be unlike anything seen before and marks the latest chapter in the story of the Rolls-Royce UT design vessels, which have been pioneering oil and gas exploration for the past 40 years.”

SOX REDUCTION REGULATIONS DRIVING EXHAUST GAS CLEANING INTEREST

Scrubbing Up Well IN JUST A FEW SHORT MONTHS VESSELS OPERATING IN THE NORTH AND BALTIC SEAS, THE ENGLISH CHANNEL AND IN NORTH AMERICAN WATERS, WILL BE REQUIRED TO EMIT LESS THAN 0.1 PERCENT SOX – a considerable reduction on the current 1 percent. High amongst the concerns of vessel operators is management of associated costs and one solution is already proving popular as the scramble for compliance begins – exhaust gas cleaning systems, or scrubbers.

SPLIETH OFF DIR EC TOR

We’re convinced that scrubbers are the right way to proceed in complying with upcoming legislation.

I

nternational accountancy and consultancy service Moore Stephens says that some shipping companies are going to find the costs of compliance with the new regulations a challenge.

Especially as they arrive alongside other new regulations, making for a string of almost simultaneous new investments. They point out, for example, that the cost of ballast water management systems, a solution to the IMO Ballast Water Management Convention, can range from EUR 400,000 right up to EUR 4 million, with additional implications for operating costs and the end price to the client.

Pick a Number, Any Number

“Think of a number. Any number will do, so long as it is very big. Then double it…”, says Moore Stephens Shipping Partner Michael Simms. He explains that the costs of such technology are largely unknown at this stage. “Scrubbers, meanwhile, may be the most cost-effective solution for some when addressing the SOx /NOx dilemma. One thing is certain however – shipping is going to have to find a great deal of money over the next few years.”

The application of scrubber systems allows the operator to comply with the new rules for the Emission Control Area (ECA) and yet continue to use heavy fuel oil, reducing costs at a stroke.

pH Neutral

The companies providing this technology are already experiencing increased demand for their solutions as the dawn of the new regulations draws closer. Wärtsilä, for example, have recently been awarded an order to supply exhaust gas cleaning systems for six Finnlines vessels.

Wärtsilä have 100 scrubber units either installed or on order for 51 vessels. The company has been awarded the IMO certificate for exhaust gas cleaning systems by classification societies DNV GL and Bureau Veritas.

The Finnlines order requires one scrubber system for each of the six vessels. The two main engines on each of the ships will be connected to a single integrated scrubber system. Wärtsilä’s system is

www. s h i p b u i l d i n g - i n d ustr y.eu

SOx Wartsila.indd 31

an open loop solution, which uses seawater to remove SOx from the vessel’s exhaust. The natural alkalinity of the salt water neutralises the acid that occurs as a result of the reaction between the SOx and the water, eliminating the need for chemicals.

Emanuele Grimaldi, President and CEO of Finnlines, says environmental compliance and cost efficient operations are key factors in the success of Finnlines. “The installation of Wärtsilä scrubber systems on our recent series of six modern RoRo vessels is a major step in the implementation of our strategy. The extensive experience that Wärtsilä has in this area, together with the retrofit services the company can provide, will greatly help us during the engineering and installation phases of this programme.”

Clean SOx

Finnlines are particularly busy preparing for next January and have also ordered PureSOx scrubber systems from Alfa Laval for four existing RoRo vessels. The retrofits will be carried out on the vessels Finnhawk, Finnkraft, Finnmill and Finnpulp at Northern European yards between December this year and January 2015.

All four of the vessels have four-stroke MAN engines, but will have differently configured PureSOx systems. The Finnhawk and Finnkraft, with their single 12.6MW engines, will receive single-inlet scrubbers, whereas the Finnmill and Finnpulp each have two 9.45MW engines and will receive multiple-inlet scrubbers.

“Having multiple inlets will allow us to reduce the space and equipment requirements aboard the Finnmill and Finnpulp by using one scrubber to handle both engines,” says René Diks, Manager Marketing & Sales Exhaust Gas Cleaning at Alfa Laval.

Meeting the Future With Confidence Alfa Laval are providing all four of the vessels with open-loop systems, sized specifically for the Baltic, as Mr Diks explains: “The further north you sail, the less alkaline the Baltic Sea becomes. This has to be taken into account when installing an openloop system for these waters, because the

alkalinity of the seawater has a direct impact on the scrubber’s cleaning capacity.”

Finnlines has chosen a scrubber design that is open to the possibility of hybrid conversions at a later date, paving the way for compliance with further regulatory changes, as Mr Grimaldi suggests: “The PureSOx systems aboard our vessels will provide compliance and fuel economy in 2015, but also the flexibility to add closedloop operation down the road. They will enable us to meet the future with confidence.”

Right Way Forward

Alfa Laval have also received an order from Dutch shipowner Spliethoff to supply PureSOx systems to five ConRo vessels to be retrofitted during 2014. Spliethoff already have PureSOx installed on board their vessel Plyca. Director Frank Louwers says the decision to order five more systems was based on the success of this experience. “As a frontrunner with MV Plyca we’ve gained a lot of practical experience with scrubber technology. The PureSOx system works well and we’re convinced that scrubbers are the right way to proceed in complying with upcoming legislation.”

The installation on board the Plyca and the new orders are multiple-inlet systems able to clean the exhaust gas from the main and auxiliary engines.

DIY

Deltamarin and Langh Ship have come together to form joint venture DeltaLangh with the aim of providing a cost-effective solution to the forthcoming legislation.

Langh Ship considered the closed loop solutions available in the marketplace then decided, with Deltamarin, to produce their own. Managing Director Hans Langh already had 40 years of experience in water treatment systems through his company Industrial and Ship Cleaning Services Hans Langh.

The result of this decision has been trialled already for one year aboard Langh Ship’s vessel Laura. The 6,500t vessel, with her 6MW main engine, has operated without interruption for a 12-month period, including throughout a Baltic winter and the icy conditions this entails.

“The scrubber has proved to be very easy to operate, stable and does not add much extra workload for the crew,” says Langh Ship’s Technical Adviser, Reino Verosaari. Mike

The scrubber is located within the funnel seen here aboard the vessel Laura.

Laurilehto, Managing Director at Deltamarin, explains his company’s interest in teaming up with Langh Ship on the project: “When we heard about this new innovative solution… we knew that this was a product Deltamarin wants to be involved in.”

The partners in the joint venture are optimistic that others will see the viability of the product. “The scrubber has been such a success that we are sure it will benefit other ship owners as well,” says Laura LanghLagerlöf, Commercial Manager at Langh Ship. i. www.alfalaval.com i. www.deltamarin.com i. www.langhship.fi i. www.wartsila.com

ALFA LAVAL AND MAN DIESEL & TURBO DEVELOPING EFFICIENT NOX ABATEMENT SYSTEM

Ready for TOMORROW CHALLENGES POSED BY THE IMO TIER III NOX ABATEMENT REGULATIONS SET TO COME INTO FORCE IN 2016 ARE STIMULATING FRESH IDEAS AND EXPERIMENTATION ACROSS THE MARITIME SECTORS. CHANGES ARE inevitable, it only remains to be seen which of the innovations currently being trialled will pass into common usage in the future. MAN Diesel & Turbo, along with Alfa Laval, are developing the Exhaust Gas Recirculation (EGR) solution. The potential of EGR is confirmed by performance aboard two Maersk vessels.

EGR Technology have been trialled on board two Maersk vessels, the Alexander Maersk and the Maersk Cardiff (pictured).

EGR is one of two technologies currently under development that seek to deliver Tier III compliance without recourse to LNG. EGR, which involves the recirculation of exhaust gas, is integrated into the engine of a vessel and prevents the formation of NOx during combustion. Its rival, Selective Catalytic Reduction (SCR), on the other hand, is an after-treatment solution that removes NOx via a catalyst.

Proven Credentials

The emission-reducing capabilities of EGR can be seen in installations aboard the container vessels Alexander Maersk and Maersk Cardiff. The 1,092TEU Alexander www. s h i p b u i l d i n g - i n d ustr y.eu

Alfa Laval def.indd 35

Maersk had her MAN B&W 7S50MC engine retrofitted with an EGR prototype in 2010.

To date she has spent in excess of 2,200 hours operating at 50 percent NOx reduction over today’s basis emission level.

The findings of this initial, retrograde, installation have been put to use in the 4,500TEU Maersk Cardiff. The new build’s engine is fully Tier III compliant and has been in operation for well over 1,000 hours up to now.

EGR can also be operated in an optimised Tier II mode. MAN Diesel & Turbo introduced this in 2012 as a feature of the MAN B&W 6S8OME-C9 engine – that which has been installed aboard the Maersk

Cardiff. The Tier II mode facilitates a reduction in fuel consumption of approximately 4g/kWh at partial load.

Safeguarding Efficiency

An integral part of the development of MAN’s EGR has been incorporation of Alfa Laval’s PureNOx water treatment system.

Kristina Effler, Business Manager, Water Treatment Exhaust Gas Emissions at Alfa Laval, says, “Alfa Laval is proud to be part of those pioneering EGR installations, where our PureNOx has the vital role of cleaning the wash water in the wet scrubber. No other vessel has EGR installed and operating reliably at Tier III.”

SHIPBUILDING TECHNOLOGY

EGR depends on the effective cleaning of the wash water in the wet scrubber, which operates in a closed loop. PureNOx is based on high-speed centrifugal separation for the removal of potentially engine-damaging combustibles built up due to the use of diverse fuel types.

“PureNOx keeps soot and other compounds from the exhaust gas from accumulating in the scrubber,” Ms Effler explains. “It safeguards efficiency, reduces maintenance and prolongs the service life of engine components by protecting them against corrosion. In addition, PureNOx enables the discharge of excess water in accordance with IMO criteria.”

Another advantage of EGR is its consistency in the face of varying engine loads. Mr Larsen says, “There has been no effect whatsoever when changing engine load. The EGR system has run without any problem and the emission reduction performance has not been affected.”

Competitive Edge

In addition to lowering emissions in line with forthcoming regulations, it is imperative that solutions also offer reductions in fuel costs. This is especially the case as ship operators seek to offset the costs of installing NOx abatement solutions to their vessels. Here, opines Ms Effler, EGR has the edge over SCR. “EGR is the only NOx abatement technology that offers fuel savings in addition to Tier III compliance. As such it is the only technology that will offset the initial investment over time.”

A look at associated costs of EGR and SCR installations would, initially at least, seem to point towards the catalytic system as the more cost-effective of the two. However, the inevitable outlay on consumables and maintenance, Ms Effler says, makes the catalyst free EGR solution the cheaper option over time.

Taking on-costs into consideration, SCR operates at 7 - 10 percent of fuel costs, whereas EGR is able to function at just 4 - 6 percent of fuel costs in Tier III mode.

Reducing the Workload

Associated costs represent just one element that vessel operators are likely to be weighing up when selecting a NOx abatement technology. Amongst the other potential causes for deliberation is the size of the installation itself and any additional requirements it may place upon the crew.

Again, Ms Effler has confidence that EGR represents the most efficient option when faced with such considerations.

“An EGR system is compact because nearly

Looking to the Future

everything – including the water cleaning – is integrated into the engine itself,” she explains. “Compare this to an SCR system where significant engine room is needed for the reactor and other components. Likewise EGR is fully automated and has no filling elements to clean and replace, so it requires very little from the crew.”

Kurt Larsen, Chief Engineer aboard the Alexander Maersk, confirms the importance of an easy-to-maintain system for a modern crew. “Today the workload for the crew is big enough already, so it’s essential that there isn’t yet another system to maintain frequently,” he says. Fortunately, he’s also in agreement with Ms Effler when it comes to EGR’s credentials in this area. “The potential of EGR seems good in terms of achieving a low-maintenance system,” he states.

PureNOx systems have been delivered to Chevron Corporation for the integration of EGR on two new build vessels. Lighter than the two Maersk vessels, these are to be powered by MAN B&W 6G7OME-C9.2 engines. A further delivery has also been scheduled to Mitsui Engineering & Shipbuilding. Alfa Laval is not seeing these successes as an opportunity to rest on its laurels however and is steaming ahead with further product development plans.

“We are actively pursuing new possibilities, such as the potential of combining the EGR water cleaning system with that of a wet SOx scrubber,” confirms Ms Effler. “What we’ve seen aboard the Alexander Maersk and Maersk Cardiff is exciting and we on the PureNOx team expect further exciting developments as 2016 approaches.” i. www.alfalaval.com

DENMARK LNG-POWERED FERRY SERVICE

Forward THINKING DENMARK’S FIRST EVER LNG-POWERED DOMESTIC FERRY VESSEL, DESIGNED

BY OSK SHIPTECH, HAS RECENTLY TOUCHED WATER FOR THE FIRST TIME AT THE REMONTOWA SHIPYARD IN GDANSK, POLAND. ONCE OPERATIONAL THE VESSEL will carry passangers on a regular service between Hou, Jutland and Saelvig, Samsø in Denmark. OSK’s Kristian Lind tells ShipBuilding Industry’s Ben Littler that the ferry represents an investment in a more gas-oriented maritime future.

NAVAL ARCHITECTURE & DESIGN

“LNG was a sensible choice of fuel for this vessel. The ferry service runs up to eight return trips per day at 14 knots, which is easily within the capacity of the fuel tank.

Because the crossing is so short there was no need to fit a large LNG tank to the vessel, which would have limited space for passengers and vehicles,” says Mr Lind explaining how OSK reached the conclusion that the domestic crossing would best be served by LNG fuel. Had the distance been greater the vessel would have required the type of large tank frequently associated with LNG-powered ships. As it is, OSK have outfitted the Samsø ferry with a 40m3 tank.

Thorough Analysis

“Actually the tank will hold enough fuel for around 3 or 4 days, but bunkering will be carried out daily in Hou, after the final crossing of the day,” he continues. The Hou – Samsø ferry service is currently operated

by Faergen, who have a contract with the local authority, Samsø Kommune. The municipality, however, considered that there might be a more cost-effective way to run the service.

To that end they approached OSK ShipTech to carry out design and tender for a new ferry. With the results of the tender it quickly became apparent that there was an option to improve cost-efficiency on the route: LNG.

Looking Into the Future

OSK recommended a dual fuel engine, capable of running on diesel or LNG. This enables the municipality to switch to the most cost effective fuel should the cost of the other increase dramatically at any point.

However, it is envisaged that the ferry shall run on LNG for the vast majority of the time.

Furthermore, Mr Lind suggests, over time this will equal great savings for the authority. “Although things are a little slow at the moment for LNG,” he says referring to the well known ‘chicken and egg’ situation resulting from reluctance to invest in either LNG vessels or infrastructure until one or the other becomes abundant, “this ferry is going to be in operation for 30 years and we are confident there is going to be a better market in the future.”

He points out that OSK ShipTech have also been asked by Samsø Kommune to source the fuel for the ferry together with EMUC (Maritime Development Centre Europe). In this they have been insistent that anyone tendering for the contract offer a price based on the LNG price index and not, as is the more conventional practice, on the www. s h i p b u i l d i n g - i n d ustr y.eu

Samsoe ferry.indd 39

diesel fuel index. This is in anticipation that an improving market in the coming years will equate to lower prices for LNG.

Tip of the Iceberg

Mr Lind points out that the LNG technology is getting closer to Denmark, which will make bunkering cheaper than it has been historically. In the past LNG – the bulk of which is transported via a subsea pipeline running from Norway to Belgium – has had to be brought in from the Port of Zeebrugge.

It is hoped that soon the closest available production terminal will be located in Hamburg, a mere 300km away and the situation looks set to improve further.

“I see the solution, not this year, not in 5 years time, but maybe in 10 years time.

We’ll have our own production plant in Denmark – on Samsø. Eventually the entire infrastructure will be able to be powered

by LNG.” Of course, this has major implications for the future of shipbuilding for vessels operating in the region, suggesting that the construction of the Samsø ferry might, in fact, be just the tip of the iceberg for LNG powered vessels in the area – especially as emissions regulations continue to tighten.

Car Capacity

The ferry is a fraction under 100m in length, with a beam of 18.5m and draught of 3m.

She will be transporting up to 600 passengers and will have a capacity to carry up to 160 cars or 16 trucks.

She will be powered by four 1,000kW Wärtsilä 6L20DF generator sets and a propulsion system from Schottel.

The interior of the ferry has been provided

by Famos, who are also located in Poland, close the port area of Gdansk and Gdynia.

The Samsø ferry might be just the tip of the iceberg for LNG powered vessels in the area.

As a first, the LNG tank was also produced in Poland. The paint was supplied by marine coating specialists International Paint.

Good Looking

Mr Lind explains that the ferry will not look like a conventional LNG-powered vessel.

“It’s a simple solution requiring no pumps and no pipes on deck. No one would suspect that it wasn’t a conventionally powered diesel engine just by looking at it.”

He says there were two choices when it came to ensuring the safety of the vessel and that OSK selected the most costeffective method, without compromising the safety of those who will be travelling on the vessel.

“There are two ways of making such a vessel safe: one is to use double walled piping and then conventional equipment in the engine room. The other is to use single walled pipes, but then everything in the engine room has to be arranged for ‘emergency shut down’. This is by far the more expensive method. The double walled pipes are every bit as safe and far more economical, so we opted for that method with the Samsø ferry.” i. www.osk-shiptech.com

ENERGY EFFICIENCY MONITORING IS BOTH GREEN & ECONOMICAL

A Logical Choice A SHIP THAT CONSUMES LESS FUEL OBVIOUSLY SAVES MONEY – IT’S NOT ROCKET SCIENCE. HOWEVER, IT IS NOT JUST A QUESTION OF SLOW STEAMING TO SAVE MONEY. IN TERMS OF FUEL CONSUMPTION, THERE ARE NUMEROUS factors involved that determine the optimum speed of a vessel. Editor Tom Scott spoke to Managing Director of Eefting Energy Harm Eefting whose energy efficiency monitoring system reduces operational costs, improves efficiency and reduces exhaust gas emissions.

WORDS BY TOM SCOTT

R

ising fuel costs and compulsory compliance with international regulations leads vessel owners to try to consume less fuel. Eefting’s energy efficiency monitoring system (E2) monitors the efficiency of fuel consumption, speed and engine power because it turns out that in order to use less fuel, it is not simply a case of going slow. The principle is comparable to sitting in a stationary car with the engine running. “You will be operating very inefficiently,” explains Mr Eefting. “You will be consuming fuel without covering any distance.” When dealing with ships there is an optimum speed where fuel efficiency is maximised. “This is generally when the engines are running at around 50 percent capacity. For example, a ship with a top speed of 15 knots will have an optimum speed, in terms of fuel consumption, of around 8 or 9 knots.” Go any slower, and the fuel efficiency begins to decrease again.

Rules & Regs

Reducing fuel costs is not the only reason to improve efficiency though. International regulations also play a part in the whole story. For example, the IMO Marine Environment Protection Committee has mandatory measures to reduce emissions of greenhouse gases (GHGs) from international shipping. This represented the first ever mandatory global

4 0 | S B I 2 0 1 4 | Vo l um e 8 | Issue 3

Eefting.indd 40

greenhouse gas reduction regime for an international industry sector. Since then, the MARPOL Annex VI amendments have made an Energy Efficiency Design Index and a Ship Energy Efficiency Management Plan obligatory for all vessels at or above 400 gross tonnage.

“This system shows its worth when vessel owners are faced with compliance of compulsory regulations. Ship owners and operators can achieve realistic goals for reducing greenhouse gas emissions as well as significantly improving fuel efficiency,” informs Mr Eefting.

Especially useful for when entering SECA areas is the fact that the E2 system registers fuel oil change-overs charting the time and geographical position.

Determining Factors

“Two years of researching market needs showed us that there was a definite need for an improvement in efficiency,” Mr Eefting says. “So we developed the product and now it is taking off.” By listening to existing customers, the company reports that long term reductions of fuel costs of around 5 percent are the average (although incidental reports of 15 percent savings on certain voyages have also been reported). How is this achieved? That is the crucial question.

The answer, it seems, is to determine the optimum fuel

consumption point. The problem is that the sea is a dynamic environment – wind speed, water depth, swell and wave height all affect fuel consumption. Because this environment is constantly changing, a monitoring system must be able to constantly adapt and present this information to the captain to enable correct on-the-moment decisions.

The E2 system combines information about these external factors and combines them with data concerning fuel oil consumption, speed, propeller pitch, RPM and engine power.

The measured values are transmitted to a touch screen panel on the bridge. These values are used for calculating various efficiency factors and emission values.

Powerful Information

The system assembles the data, together with the ship’s position and time of generation. This is then exported to a ship’s computer system in the form of sea voyage reports and noon reports. These are stored for further analysis, onboard or can be emailed onshore without the ship’s crew having to interfere. As well as providing information for shortterm decision making, these data can then be used for longterm trend analyses of the whole propulsion installation, propeller performance and hull fouling. Interestingly, the operational habits of various crews and the performance of different sister ships within a fleet can be compared.

“Of course, most of the time a ship sailing from A to B has

a specific ETA to meet,” says Mr Eefting. “In this case, the demands of the customer naturally come before fuel efficiency yet our system gives valuable information for the ship’s officer to find optimal speed settings to meet the ETA and sail as economically as possible, whether this in regards to fuel consumption, costs per nautical mile or optimised profit per voyage.”

Trend analysis yields crucial information – giving vessel and fleet managers a powerful tool to make informed decisions on operations, maintenance and docking intervals. “The

The fully installed E2 system consists of a touchscreen panel and NMEA data collecting box on the bridge, an Ethernet convertor box in the engine room and an optional slave panel located in the engine control room.

Data transfer between the engine room and the bridge utilises the vessel’s Ethernet system. This method does not interfere with the ship’s computer network, thus eliminating the installation of additional signal cables between the two areas. Where no computer network is available, only one signal cable between the engine room and the navigation bridge has to be installed resulting in minimal installation costs.

In terms of measuring equipment, the system has a minimal requirement of a fuel oil consumption meter with temperature transmitter, a speed signal (from a GPS receiver) and a pitch/RPM transmitter as well as fuel and power measurement of the auxiliary engines and oil fired heaters.

Data collection, and therefore potential for analysis, can be extended with the addition of a propeller shaft torque meter and a shaft generator power transmitter.

SAY THE WORD ‘RORO’ TO MOST PEOPLE AND THEY WILL AUTOMATICALLY ASSUME THAT YOU ARE TALKING ABOUT A VESSEL THAT CARRIES WHEELED CARGO SUCH AS CARS, TRAINS OR TRUCKS AND TRAILERS LOADED ONTO THE vessel via the stern. Danish Naval Architects, Knud E Hansen A/S, have come up with a design that is more flexible, more efficient and is also an award winner. ShipBuilding Industry’s Tom Scott spoke to the company’s Senior Naval Architect, Christian Damsgaard, to get the low down.

RoRo Specifically, it was the efficient and innovative design of internal cargo arrangement that was recognised by the ShipPax Award jury. “Although the vessel has some container capacity, she is specialised in handling all types of cargo,” informs Mr Damsgaard. “Loading flexibility is therefore important.” The broad range of cargo that the vessel can handle demonstrates this flexibility. In fact, the Bahri Abha has 364 dedicated container positions but this can be significantly increased if MAFI trailers and cassettes are used. This is combined with an impressive 24,800m2 RoRo cargo capacity.

T

he 12th Annual Ferry Shipping Conference took place this year on board the cruise ship Romantika that was sailing between Stockholm and Riga. As in previous editions, the conference was the occasion to present the prestigious ShipPax Award. Launched in 1999, the ShipPax Award stimulates innovative solutions by promoting noteworthy design features on newly delivered ferries, RoRo and cruise vessels.

This year’s winner was Knud E Hansen A/S in recognition of the design of the deep-sea RoRo vessel, Bahri Abha. The award is considered by many to be the most

www. s h i p b u i l d i n g - i n d ustr y.eu

prestigious trade award in the combined ferry, RoRo and cruise industry.

Diverse Cargo

The 225m Saudi-owned Bahri Abha design certainly rethinks the typical RoRo. “This is not a typical RoRo vessel – one that has lanes for trucks,” explains Knud E Hansen A/S Senior Naval Architect Christian Damsgaard.

“The Bahri Abha, however, sails with so many kinds of cargo that there are no lanes or dedicated areas for special cargo.” The vessel is also optimised for fast and flexible loading and unloading procedures.

“For a RoRo cargo vessel, the most important design criteria after fuel consumption is efficient layout as it reduces the time in port,” continues Mr Damsgaard.

“An efficient layout also increases the flexibility during loading and unloading and reduces damages to the cargo.”

The Knud E Hansen A/S designed layout is certainly flexible as loading can be completed both via ramp and cranes. “On top of this there are large flush hatches and a large sliding door, meaning that you can load directly into the forward hold and since the hatches are flush you can drive on them and into the hold,” explains Mr Damsgaard.

The design is also efficient as the aft loading area gives the possibility of loading all decks simultaneously. “This results in undisturbed driving lines where loading trucks can drive faster and safer.” In addition to this there are a few features that give the possibility of loading very large items. “The Bahri Abha can carry all types and sizes of goods,” continues Mr Damsgaard. “From standard trailers and containers and heavy-lift cargo

to oil exploration equipment and construction machinery.”

Fuel Saver

What’s more, the vessel is fully independent with regards to manoeuvring and loading and unloading procedures, doing away with the need for shore cranes or harbour assisting tugs. What sets this vessel apart from the rest of the Bahri fleet is that she is smaller, yet boasts greater cargo lifting capabilities. She has two deck cranes, each with a 120t @ 15m lifting capacity.

At present, the Bahri Abha and her five sister vessels operate a route from Saudi Arabia to the American Eastern seaboard and back again followed by a return trip to India. This new generation of RoRo vessels consumes an estimated 45 percent less fuel on this route than the older ships they replace, thereby delivering considerable cost savings.

Such significant fuel savings are achieved by a number of factors – “There is really no single item that lies behind the saving,” says

www. s h i p b u i l d i n g - i n d ustr y.eu

Knud E Hansen.indd 47

Mr Damsgaard. “The construction was optimised to avoid the excessive use of steel and in the initial stages the vessel was lengthened without increasing the deadweight, resulting in a more slender and efficient vessel.”

Tailor-Made Solutions

During the model testing phase, there were also benefits to be found: “The lines were optimised to the extent that there really was no more to gain.” Inside the vessel many systems are simply more efficient compared to those of the older sister vessels that date back to the 1980s: “The main engine was down rated and thus given a lower specific fuel consumption.”

The Danish naval architecture bureau provided the concept and tender design and also supported the owner throughout the construction process. “This was a true tailormade solution meeting the owner’s requirements,” says Managing Director Finn Wollesen Petersen. “We are extremely happy to have won this award. I am very

proud of the whole Knud E Hansen team.”

On the overall success of the project, Mr Damsgaard concludes that “it is more related to a good design where the owner understood the importance of allowing time for the designers to do a good job and explore various solutions before selecting the final path.” i. www.knudehansen.com

SEC-GRONINGEN’S OFFSHORE VESSEL DECK GEAR

Pulling Force FROM THEIR TRADITIONAL TRADE IN EQUIPMENT FOR BULK CARRIERS, SEC-GRONINGEN, A CIG COMPANY, HAVE SEEN INCREASING BUSINESS for the offshore industry in recent years, providing anchor handling and four-point mooring equipment. Head of Sales Martin Cremers explains the shift in demand, particularly for electric frequency controlled winches.

T

he Central Industry Group (CIG), a Dutch conglomerate in steel construction design, engineering and production, has rebranded group members to reflect their role in providing ship owners with total shipbuilding solutions. For example, Vuyk Engineering Groningen is now CIG Maritime Technology and Shipkits has become CIG Shipbuilding.

The rebranding exercise is the latest rapprochement in the group members’ longstanding cooperation. The idea is that, together, they can provide a one-stop-shop for the industry.

Recently they have developed designs for costeffective PSVs, light construction subsea vessels, dive support vessels, and walk-to-work type wind support vessels.

Anchor & Mooring Winch Supplier

While these designs paint a clear picture of CIG’s strategic ambitions, the individual group members remain focused on their respective markets. For example, Ship’s Equipment Centre Groningen (SEC) (now sporting the identifier ‘A CIG Company’ in their logo) has a long history of designing and manufacturing winches and other deck equipment. From their traditional trade in equipment for bulk carriers, SEC-Groningen have seen increasing business for the offshore industry in recent years, providing anchor handling and four-point mooring equipment for vessels utilised by marine contractors around the world.

Particularly popular with the offshore industry is the company’s Ten Horn brand of electric frequency controlled mooring winches, with pulling force capacity up to 100t.

“From PSVs, pipelay vessels and all kinds of offshore vessels, they’re using these systems,” says Martin Cremers, Head of Sales at SECGroningen, “[Four-point mooring] is more required these days, we see more offshore support vessels and diving support vessels are asking for these kinds of products. One reason is for safety reasons during diving operations. They don’t want to use DP, so then they put it on the four-point mooring system.”

Environmental Factors

SEC-Groningen has production facilities in the Netherlands and in Shanghai. The machinery produced under license in China is identical to the Dutch original, with the same prime Western

www. s h i p b u i l d i n g - i n d ustr y.eu

SEC Groningen.indd 49

components. As well as standardised designs, SEC-Groningen develops all kinds of custom winches, which are also a growing part of the company’s new turnover from the offshore industry, Mr Cremers confirms. He says more of these designs steer away from the hydraulic option.

“Across the whole range, we’re seeing more and more clients choosing electric frequency controlled winches. It’s also to do with the environment. They want to get rid of the hydraulic oil as much as possible on deck, avoiding problems with leakage. Noise is another factor. If you have a hydraulic pump, then you’re always going to have a lot of noise.”

The electric frequency controlled winches still have the same benefits as hydraulic winches, like stepless speed control and full control of torque, but have more options. “You have low start current, very low maintenance because you don’t have the hydraulic parts inside, it saves energy and also you don’t have so much piping and hydraulic oil on the vessel.”

Low Maintenance

Frequency control provides more options in control stands and makes it easier to have wireless radio control. The electric motor is always protected from overload – if the forces get too high then the brake automatically takes over.

Another important issue with mooring winches is self-tensioning. The hydraulic versions typically operate with a load pin, which can be maintenance intensive, Mr Cremers says. “Another benefit of frequency control is that you have timecontrolled tensioning directly in the electric motor. You don’t need a load pin, so you can avoid problems with the self tensioning.”

SEC-Groningen delivers winches with a separate power pack, but the company also integrates power directly into the winch itself. “For the shipyard it’s much more convenient, they can directly install the winch on deck, it has a complete foundation underneath, so the outlining is not necessary. You only need to install the electric wires for the electric motor. [Our winches] have a compact design, no tubes or hoses on the outside, so everything is built into the gearbox of the winch itself.” i. www.centralindustrygroup.com

Outstanding Energy Management SAVINGS FOR GEA WESTFALIA SEPARATOR

GEA Westfalia Separator has implemented an energy management system in line with German and European standards.

By developing previously unused efficiency potential, it has been possible not only to significantly reduce energy costs along the entire line by means of lower use of resources but also to reduce carbon emissions. The conditions for sustainable and energyefficient production have been created particularly as a result of the new conversion measures at the company’s Oelde facility. The key aspect of the energy management system is the

company’s own combined heat and power plant in combination with an absorption refrigerating system (pictured). This enables use of a combined power heat and refrigeration system, resulting in significant savings of primary energy compared with conventional energy generation.

For its exemplary energy management system, the Oeldebased engineering company was recently awarded the TÜV certificate according to DIN EN ISO 5001. i. www.gea.com

Compressed Air Savings VPVISION MONITORING SYSTEM

Compressed air is an expensive product that is widely used in the shipbuilding industry – from pneumatic components like valves and accuators to sandblasting equipment. However, a lot of it is wasted due to leakages or nozzle wear. Increased resistance in piping systems due to corrosion can also result in unnecessary increased energy costs.

VPInstruments’ VPVision is a modern energy management system that monitors and analyses compressed air systems. Via a web browser, complete systems, from compressor system to end-users, are mapped out and reports

displaying the efficiency, the total costs and the consumption per department are generated.

Permanent monitoring and analysis is the first step in identifying and maintaining problems, so that the savings are subsequently realised year after year. By using the VPVision monitoring system, leaks become visible and the maintenance schedule can be adjusted. In practice, the costs of generating compressed air can be reduced by as much as 20 to 50 percent. i. www.vpinstruments.com

The port of Rotterdam uses the CO2 Performance Ladder as a commissioning party.

Managing the Nerve Centre LOGIA GOES LIVE

Logia warehouse management system (WMS) is a specialised warehouse management system that optimises management of the internal flow of goods by integrating warehouse sections into a single system. Through efficient logistics management, Logia offers increased profitability and competitiveness.

Having already implemented the Logia WMS at its warehouses in Denmark, MAN Diesel & Turbo are employing Logimatic’s same warehouse control solution in Zürich. In Denmark, the system

controls fourteen vertical lifts of four different brands. The Zürich implementation is now live as of June while adding a fifth brand of lift.

Logia WMS controls all vertical lifts in one solution that is fully integrated with MAN’s SAP solution – making it an internal logistics nerve centre. As the system is independent of brand, the benefit to MAN is that only one interface needs to be maintained. i. www.logimatic.com

Climbing the Ladder REWARDING CO2 REDUCTIONS The CO2 Performance Ladder is a tool to encourage companies to be aware of their CO2 emissions and to look out for new ways to save energy, use materials efficiently and to use renewable energy. The idea operates on the basis of two principles: attaining the best possible practical results and maximising innovation with minimal restriction of a company’s operations.

Owned by the Independent Foundation for Climate Friendly Procurement and Business, the CO2 Performance Ladder is divided

into five levels, each with a fixed set of requirements. A company can reach the next level through improving existing processes and through innovations in technologies and methods. The higher up the ladder a company climbs, the more advantage it gains in the tendering process – in the form of a nominal discount on tender price. Such rewards aim to stimulate the private sector to incorporate CO2 awareness in the way it organises its activities. i. www.skao.nl

avyard’s new design is for a vessel displaying fuel economy and environmental friendliness.

A vessel that is able to operate as efficiently as possible, with the least amount of influence from exposed waters, in areas such as the Arctic. To facilitate the required efficiency, Havyard have employed the most up-to-the-moment technology.

Catalyst Prepared

We have two main focal points… customers’ demand and use of the latest accessible technology.

The vessel is designed to meet the latest environmental standards, such as Clean Design and its low emission engines are prepared for catalysts.

Havyard’s hull lines are based on those of a smaller PSV vessel – the Havyard 832 LWE – and on offshore wind farm service vessels. As well as reducing fuel consumption and providing a greater degree of crew comfort, the lines make it easier to keep the hull free from ice during operations in Arctic waters.

Arve Helsem Leine, Design Manager of Havyard Design & Solutions said, “When we develop a new ship design we have two main focal points.

methods for testing. We also work closely with key suppliers in developing good solutions for our designs and hybrid battery power is a good example of this.”

Precision Positioning

Simply put, the idea is the same as that used in hybrid-car technology: to produce energy as efficiently as possible, whilst ensuring that extra power is available as and when it is required. PSVs typically experience a large range of variables in the amount of energy they need – for example, sailing requires a different amount of energy than is usually required during operations at an offshore oil rig. Weather and currents are two of the factors that play a role in this.

Mr Leine explains the implications of this: “In traditional diesel-electric propulsion systems the diesel generators’ load will vary according to the alternating energy needs.”

Photo courtesy of Fuglefjellet

This means that diesel engines cannot constantly operate within a local area where these engines have the lowest possible fuel consumption. “With hybrid battery power you can constantly operate diesel generators at an optimal level. When energy demands vary you can either charge or discharge batteries, depending on whether the energy demands are lower or higher than the capacity of diesel generators in operation. Response time in relation to variation in power demands is also a lot shorter, so there is a quicker transfer of power to the ship’s thrusters, which ensures a more precise and secure positioning, for example in operations by an offshore rig.”

Faith in the Future

This will be the fourth time that Havyard have designed and constructed a vessel for

www. s h i p b u i l d i n g - i n d ustr y.eu

NES.indd 57

Iceland-based Fafnir Offshore. Steingimur Erlingsson, founder and CEO of Fafnir, speaking of the vessels that Havyard has built for his company, said that they represented an “… indication that Iceland is taking its first step in the offshore industry.”

He spoke highly of his relationship with the shipyard: “… it has been a privilege working with Havyard when it comes to finding solutions for technical challenges… In the Havyard 83 WE ICE design, we have continued our cooperation and further developed the PSV concept… Havyard really does live up to is vision ‘Improving Life at Sea’ and we have great faith in the future and our cooperation with Havyard.”

Herald of a New Era

For NES, this will be the second time they have supplied a diesel electric system for a Fafnir Offshore vessel. The first was for a HD832 L WE, which is due for handover in Q3 of this year. However, this is the first time that the system will feature QUEST technology.

NES say that QUEST technology will open up a new era in the electrical propulsion market. QUEST 1 and 2 are two different engine storage systems. They enable the running of engines on one diesel generator set. When increased power is required it is supplied from the batteries, which are in turn charged by spare energy from the generator set.

placing it close to the main switchboard.

NES say that the Quadro Drive has proven itself, with over 22 systems in operation already. Used with QUEST, further benefits can be experienced, for example, a battery pulse with either DC/AC convertor or DC/DC convertor. Furthermore, the fact that QUEST utilises existing products, readily available off the shelf, means there is no need to gamble with unproven, prototype technology.

Power on Demand

NES has, through the development of software, studied various vessels’ fuel and power demand. This has enabled them to establish necessary criteria to calculate the average level of power and any subsequent boosting power required from the battery.

Conventional diesel-electric systems typically offer between 15 and 50 percent fuel savings, dependent on mode. With QUEST technology, however, NES suggest 15 percent savings to be possible.

Altogether, the system coupled with Havyard’s hull design, sees fuel consumption reduced by between 30 and 40 percent in comparison with a conventional, diesel powered PSV. Additionally, because QUEST creates less demand for multiple generator set usage, diesel engine maintenance requirements are also lowered.

Crucially, just as more robust emissions regulations come to pass, QUEST’s reduction of diesel use also makes for reduced NOx and SOx output. i. www.havyard.com i. www.norwegianelectric.com

On a Quest

QUEST has been part of NES’s planning since 2010, when they began to develop the Quadro Drive. “Our philosophy has always been to prepare a diesel-electric and hybrid electric system with modular ‘add-on’ capability,” NES have stated in a press release. “Like other companies we too studied the DC grid system as a possibility, but found it to be out of date, far too expensive, especially installation wise...”

NES have extended the Quadro Drive with QUEST solutions, where a convertor is incorporated into the drive. This means there is no need to decentralise the battery banks.

Space for the battery room can be found on any vessel design. NES offer the example of

REFIT, REPAIR & CONVERSION

Replacing the main engine cooling water piping using grooved-end couplings took just one week.

MECHANICAL PIPE-JOINTS DELIVER FAST & SAFE RESULTS FOR DREDGER RETROFIT

Get Into The Groove PIPING SYSTEM RENEWAL CAN BE A LONG AND EXPENSIVE AFFAIR WITH SOME SERIOUS SAFETY ISSUES. OFTEN THE WORK HAS TO BE CARRIED OUT IN LIMITED SPACE, WHICH COMPLICATES MATTERS AND ADDS TO THE TIME AND costs involved. When piping systems had to be replaced on the Canada-based Fraser River Pile and Dredge’s (FRPD) trailing suction hopper dredger (TSHD), the work had to be completed as quickly as possible. This, and the desire to avoid welding for safety reasons, led the company to select Victaulic’s grooved mechanical pipe-joining method.

T

he main engines of the 1983-built FRPD 309 TSHD recently underwent replacement of cooling water piping systems. Welding new pipes around fuel and other combustible materials obviously raises safety considerations. But as well as eliminating fire risk, FRPD Marine Technical Superintendent Igor Shlyk knew that using grooved mechanical joining instead of welding would greatly speed up the retrofit work on the TSHD.

Rapid Refit

“We’d used the Victaulic system before so I knew it would be way faster,” says Mr Shlyk. “Not only do you have fewer people involved but you don’t have to fit, cut and grind: you just order the piping and fittings, get a grooving machine and everything fits together.”

REFIT, REPAIR & CONVERSION

Not only was the installation time reduced, but the project could also get off to a quicker start because there were none of the delays associated with welding. “As a BV Class vessel, we have to have all the procedures in place including welders’ certificates, welding procedures and hotwork permits,” explains Mr Shlyk. “We could eliminate that with Victaulic products.”

There was also no need for the ultrasonic testing of welds: “In this case, we just pressure-tested the system and there were no leaks.”

A Tight Spot

The ease and convenience of the mechanical pipe-joining system helped overcome space constraints on board the

Couplings create permanent leak-tight seals and reduce system vibration.

The coupling’s unique construction results in less vibration that, in turn, mean less maintenance. “When a dredger is operational there’s a lot of vibration,” explains Mr Shlyk. “There’s a lot of flexibility with Victaulic couplings and their design makes them work like shock absorbers.”

Pleased with the final result of this recent project that took just one week to complete, FRPD is committed to using grooved pipejoining in preference to other methods.

After pre-measuring, cutting and grooving the pipe, pieces were preassembled and fitted together progressively section by section. “With welding, unfortunately you can’t do that: you have to go back and forth several times, tacking welding and removing,” says Mr Shlyk. “If we’d tried to weld, I don’t see how it could have been done.”

Similarly, any future maintenance will be much simpler. A union at every joint means that a worker needs to undo just two nuts and bolts and retighten them after replacing the gasket.

Less Vibration

Mechanical Pipe Joining Explained Mechanical pipe-joining begins by cold forming or machining a roll groove into the pipe end. The coupling housing fully encloses the gasket, reinforcing the seal and securing it in position with the use of only two nuts and bolts. The mechanical joint creates a triple seal due to the design relationship between groove, gasket and housings.

The joint’s integrity is only enhanced when the system is pressurised.

SBI OUTFITTERS PAGES Pipework Anti-Fouling

Fixed Pitch Propeller Design

Cathelco is supplying seawater pipework anti-fouling systems for a series of eight PSVs which are being built by the Remontowa Shipbuilding yard in Gdansk. Four of the 92.65m PSVs are already in service for Edison Chouest Offshore. The Cathelco systems on board the Bongo, Kudu, Sable and Oryx will protect the seawater lines against blockages caused by the growth of barnacles and mussels.

This will involve the installation of copper and ferrous anodes in the forward and aft strainers which are wired to a control panel. The remaining vessels in the series are at various stages of construction and outfitting at Remontowa Shipbuilding and will be delivered by midsummer 2014. i. www.cathelco.com

The FPP Opti Design, a new state-of-the-art fixed pitch propeller (FPP) design concept, has been introduced by Wärtsilä. The new design offers fuel savings of up to 4 percent and highly reliable full scale performance predictions. The concept has been developed utilising the latest computational fluid dynamics (CFD) technology. CFD calculations analyse not only the propeller performance but most importantly, also the interaction between the propeller and hull. This provides extremely accurate information to ensure design and parametric optimisation. i. www.wartsila.com

Structural Adhesive

Underwater Hull Cleaning GAC EnvironHull has developed the HullWiper ROV to pioneer unmanned underwater hull cleaning technology.

The ROV uses high pressure water jets as the cleaning medium, eliminating the need for brushes, abrasives and divers to deliver a safe, speedy, consistent and clean result. The HullWiper ROV is fitted with a light and camera, allowing its operator to control the cleaning process below the waterline from the support vessel. The high-speed HullWiper ROV is designed to clean up to 2,000m2 per hour, completing a full hull in a just a few hours. i. www.gac.com

Scott Bader’s Crystic Crestomer 1152PA urethane acrylate structural adhesive is specified

by CTruk as suitable for all FRP bonding, hull stringers and bulkheads, transom sections, engine beds, deck sections and for hull to deck joints. Scott Bader’s technical data for cured Crestomer 1152PA gives typical physical property values of 100 percent elongation at break and a maximum tensile strength of 26 MPa (to BS EN ISO 527-2:1196 test method). The limiting factor is the fibreglass substrate failure, not the Crestomer adhesive joint strength. Crestomer 1152PA is MEKP cured, supplied to CTruk preaccelerated in 25kg pails, which is applied by hand. It offers a good level of application flexibility on the shop floor during the bonding assembly stage, as the Crestomer 1152PA grade has an open working time of up to 50 minutes (at 2 percent w/v catalyst, 25°C) and is suitable for gap-filling joints up to 25mm. i. www.ctruk.com i. www.scottbader.com

Tank Cleaning Fan Scanjet’s latest addition to the range of tank cleaning equipment is the Water Driven Portable Gas Freeing Fan, the SC F150W. The whole tank cleaning package, fixed, portable and including fans is available from one reputable manufacturer. The SC F150W is designed as a high performance (up to 15,000m3 per hour), deep penetration unit suitable for use on all types and sizes of vessels. Weighing under 20kg, it is truly portable and using layflat hoses means setting up is a one man job. i. www.scanjetuk.com

Wencon Pipe Tape Pressure Tested

Certificated Battery Chargers Mastervolt, the Dutch-based leader in marine electrical systems, has received extensions of the coveted Det Norske Veritas (DNV) certification for a number of its high capacity Mass battery charger models. The new certificates have been applied to three of the 24-volt chargers, namely the Mass 24/25 – DNV, the Mass 24/75 and the Mass 24/100. The Mass chargers have been designed for the harshest of marine environments. The certification allows the equipment to be installed in any marine commercial operation requiring class approval, from offshore support vessels to charter superyachts. i. www.mastervolt.com

The Netherlands-based Repair Management has pressure tested the Wencon Pipe Tape.

Wencon is thereby the only manufacturer of Water activated Pipe Tape which successfully passed the pressure test at the Dutch Ship Builder IHC Merwede. This shipyard is specialised in high class offshore and dredging vessels and they have their own material laboratory. Their laboratory (named MTI Holland as a member of the IHC Group) carried out this pressure test without use of Wencon Putty. Wencon Pipe Tape passed the test at 10 bar, without any sign of leakage and the Pipe Tape is approved by IHC Merwede for their aftersales department. i. www.wencon.com

Maintenance & Repair Works The Dutch Caterpillar dealer Pon Power and MaK dealer Bolier signed a 3-year contract for the maintenance and repair works of Cat and MaK engines for the Van Oord fleet.

“The most important result is to make the maintenance works more efficient. It is our goal to improve the technical performance of the engines and to optimise the maintenance planning. This will result in a lower use of energy and lower emissions.

Van Oord is very committed to contributing to a sustainable fleet,” mentioned Jaap de Jong, Van Oord’s Director Ship Management. i. www.pon-cat.com i. www.bolier.nl i. www.vanoord.com
