Norway’s Optimarin has just completed its first revised IMO G8 compliant system installation for the Norwegian Coastguard. “Even the vessels that don’t have to install a BWM system install Optimarin,” smiles Tonje Olafsen, Project Manager at Optimarin. “I think that speaks volumes for our reputation. We’ve been exclusively focused on this specialist niche longer than anyone else – since 1994 in fact – so shipowners and operators know they can trust both our team and technology.
Working together with the Westcon yard in Ølensvåg, West Norway, the Optimarin team has just installed one of its market proven UVbased systems on the 2,189 dwt patrol vessel KV Harstad .
Unlike tens of thousands of other ships in the world fleet, the 2005 built offshore vessel isn’t actually mandated to install a BWM system. However, the coastguard chose to fit one nonetheless, ensuring it joins the fight against invasive species carried in ballast water tanks and protects the fragile marine environment.
“The efficacy of our system is second to none,” notes Olafsen, “and that was crucial in achieving the industry’s first full approval with the USCG in 2016. That really demonstrated we were leading the world in terms of compliance and, as a result, coastguard orders followed. The USCG itself chose Optimarin technology for its latest fleet renewal programme, with its first newbuild Medium Endurance Cutters set to launch from Florida’s Eastern Shipbuilding Group next year (2021). We’re proud to have installed systems with the Dutch, Danish and now Norwegian coastguards too. We see it as the ultimate endorsement. Basically, if it’s good enough for the coastguard it’s good enough for anybody!”
The installation upon KV Harstad is additionally noteworthy as it marks Optimarin’s first since obtaining revised IMO G8 certification in October. This is crucial for owners racing to install systems in the next few years, as the new approval is central to overall compliance with IMO’s BWMS Code.
“Although the revision does not apply to units already fitted, it is mandatory for the many thousands that must be installed prior to the final compliance date of 2024 (for those vessels that have delayed International Oil Pollution Surveys),” explains Optimarin’s EVP Sales and Marketing Tore Andersen.
“That means it is essential for owners and operators, such as Kystvakten, to ensure the technology they choose has revised G8 certification. Not the promise of certification, or pending certification, but actual cast iron, verifiable compliance. Choosing the wrong system at this stage is a very unfortunate, timeconsuming and expensive mistake to make.
It also helps to opt for technology that is easy to install, especially on vessels where space is at a premium - such as the 83 m long KV Harstad. The team at Westcon can vouch for this.
Somewhat unusually in the ‘traditional shipyard’ segment, Westcon has the ability to operate as a one-stop-shop – catering not only for yard duties but also handling all engineering work, from initial 3D scanning and planning, through to prefabrication of all necessary piping and final installation.
“That offers a huge advantage,” says Lasse Åsbø, Project Manager, Westcon Yards. “It means the same engineers and foremen can be involved on a project from start to finish – giving them full insight – while the seamless way we take the installation from the drawing board right through to final fitting makes progress faster, smoother and more efficient in terms of time and resources.”
For its part Optimarin sees a busy period ahead, with customers extending far beyond the spectrum of coastguards. “Yes, we do work with other segments too!” said Andersen when quizzed. “Our reliable, easy to install and operate systems are used by a wide variety of owners operating ships up to around 50,000 dwt, while our close co-operation with Sunrui ensures that, together, we can cater for any vessel of any size. We offer a complete sales and service proposition, delivering world-wide compliance and total peace of mind, always.”
Optimarin has now sold over 1,000 of its own units, with approximately 700 installed and operational. The majority of current orders are for retrofits, signalling the industry’s final move towards ensuring existing fleets meet necessary regulatory requirements.
Optimarin has also received updated USCG approval confirming its position as the only UVsystem supplier with certification for a choice of two filters. The flexibility of selecting Filtrex or Boll filters means all Optimarin components are now available from two suppliers, ensuring maximum availability and express delivery for what the company refers to as “the coming wave” of industry orders.
“The race for compliance is on,” comments Andersen, “and we’re focused on providing a seamless, high quality supply chain for shipowners and operators to satisfy demand. Being in the unique position of having a USCG certified system with two filters – not to mention a holding time of just two hours - gives us optimal flexibility and a short lead time for owners that must comply before the absolutely final IMO deadline of 2024 (for vessels with delayed International Oil Pollution Surveys).
“We’ve always been at the forefront of the market when it comes to compliance, receiving the first ever full USCG approval in 2016, and we’re constantly working to maintain that position and deliver complete peace of mind for our global customer base. This certification is further proof of that commitment.”
Heerema contract for Techcross
South Korea’s Techcross and Holland’s Heerema Marine Contractors, who owns the world’s largest semi-submersible crane vessels in the offshore energy industry, have signed a contract to install Techcross’ ECS on-board six special vessels and barges, after its delivery of two sets of ECS 6000B to the European largest HLV (Heavy Lift Vessel) in November.

strengthening advantage over large capacity vessels as well as the superior position in European market through successive orders from the three largest global offshore mega carriers, mainly in Northern Europe. The contracted vessels are two semisubmersible crane vessels and four barges. These vessels are designed to transport, lift and install heavy cargo on various coasts distributed around the world. The Techcross products to be installed are each ECS 3000B, ECS 2000B, ECS 1000B in one set to two sets or four sets installed on a single vessel. One of these vessels applied 12,000 tonnes of capacity (maximum), showing Techcross’ outstanding performance on large vessels.
This project was carried out carefully enough to review manufacturers from the beginning of this year and Techcross ECS was selected as the final product. It means that ECS received credit for its easy installation, treatment performance in huge capacity, as well as convenient AS service network can be provided anytime, anywhere. The products contracted this time will be delivered sequentially from February next year and will be completed by November 2021.
“We are happy to win large orders ahead of the end of 2020. This project is expected to be a good promotion for shipping companies operating similar type of vessels in Europe in the future, as the largest special vessel carrier in Northern Europe chose Techcross,” said a Techcross sales representative.
At the end of December 2020, the USCG issued its type approval for Alfa Laval PureBallast 2. Most owners of Alfa Laval’s secondgeneration BWM systems can now opt to continue operating in US waters, even when their Alternate Management System (AMS) approval expires.
The PureBallast 2 system generation, launched a decade ago, was developed long before the USCG presented its testing regime. As a result, certain technical modifications were needed before PureBallast 2 could undergo USCG testing. With the modifications in place, a PureBallast 2 system with a Boll & Kirsch filter completed the tests in April 2020, and the solution has now received USCG type approval.
Owners who wish to take advantage of the USCG type approval will need to perform a minor upgrade of their PureBallast 2 systems, comprising the necessary adjustments to meet USCG requirements. After upgrading, PureBallast 2 systems will be approved for operation in both seawater and brackish water.
“The transition to USCG type approval will be a simple service option for shipowners.” “Alfa Laval’s global service organisation focuses not only on securing uptime, but also on bringing customers maximum benefit from their equipment choice. With the USCG type approval upgrade for PureBallast 2, we provide yet another way to keep BWM systems optimised over time,” said Peter Sahlén, Head of Alfa Laval PureBallast.

Approval for DESMI’s system
Denmark’s DESMI Ocean Guard has announced that a new configuration of its wellknown CompactClean BWM system has been approved by both the USCG and the Danish Maritime Authority.
This configuration is named CompactClean Bulker and must be seen as an additional product line to the existing CompactClean product lines. It is designed for higher flowrates during deballast solving one of the main operational issues faced by bulk carriers complying with ballast water regulations. Some vessel types, in particular bulk carriers, often experience a need to be able to discharge ballast water faster than the time they spend on ballast water uptake.
This is related to the speed of cargo loading, which is for some cargo types and ports much faster than the speed with which they can unload cargo. The ballast water uptake and discharge speeds need to match this in order not to become obstacles to the operation of the vessel. So far typical ballast water management systems have been approved with just one max flowrate, which is the same during ballast and de-ballast operations, but now DESMI Ocean Guard introduces a tailor-made solution.
In all its simplicity, the type-approved solution enables the CompactClean system to be configured with any combination of its approved filters and UV units, and as the filter is by-passed during de-ballast the need for higher de-ballast flowrate can be accommodated by selecting a larger UV unit than filter.
“A recent example of DESMI Ocean Guard being able to provide a solution to a customer that solves this issue is for a series of bulk carriers. These vessels operate today with cargo loading being twice as fast as cargo offloading. By selecting a CompactClean BWMS with a filter with max flowrate of 750 m3/hr and a UV unit with max flowrate of 1,500 m3/hr, the vessels have been able to continue their current operation, conducting ballast water uptake at 750 m3/hr and ballast water discharge at 1,500 m3/hr,” explains Rasmus Folsø, CEO of DESMI Ocean Guard. By this added offering, DESMI Ocean Guard strengthens its market leading position, which during 2020 was further cemented with the highest order intake recorded in a year, despite the COVID-19 pandemic which did postpone a large number of BWM system retrofit projects. The first weeks of 2021 have started well with several significant orders and frame agreements, and DESMI Ocean Guard remains confident that 2021 will present another year with increasing market shares and new records in order intake and turnover.
