TECH NEWS

This has been great for us and for Weeks Marine. We were able to drastically cut down the engineering timeframe at the front of the project, get a quick start on construction, and continue construction with good information to build the vessel quickly and efficiently. Domestic operators get as much life out of their dredges as they can, so we can expect to see the R.B. Weeks work alongside the Magdalen for many decades to come.

“The integrated electrical power, propulsion, and dredge machinery package remained nearly identical to the Magdalen’s,” said D’Isernia. “Updated EPA emissions regulations required upgrading the engines from Tier II to Tier IV. It was very convenient that the Magdalen had GE [now Wabco] engines because this manufacturer opted for EGR to meet Tier IV requirements rather than urea after treatment.”

Royal IHC has also been awarded a contract for the design and engineering of a 6,500-cubic-yard TSHD for Cashman Dredging and Marine Contracting Co., LLC of Quincy, Mass. The new vessel will complement Cashman Dredging’s current fleet of specialized dredging equipment and will primarily service the coastal protection and navigation maintenance markets when it enters service in 2024.

Biggest in U.S. fleet

What will be the largest TSHD in operation in the U.S. when it is delivered, is a 15,000-cubic-yard hopper capacity vessel under construction for Seattle, Wash., based Manson Construction Co. at the Keppel AmFELS shipyard in Brownsville, Texas.

To be named Frederick Paup, it has a length of 420 feet, breadth of 81 feet and draft of 28.5 feet. Slated to be fully operational by spring 2023, it marks Manson’s single biggest investment in its 115-year history.

Designed in collaboration with naval architecture firm Hockema Whalen Myers Associates Inc., the dredge is to be equipped with three Schottel type SRP 510 L FP RudderPropellers. Schottel says that the well-elaborated hull design concept allows for the propulsion system to be integrated in an exceptional manner. The aft appendages are optimally tailored to the rudder propellers in order to supply the thrusters with the lowest-possible turbulence flow. A long propeller arm length allows for an arrangement at the stern in portside, center and starboard positions with convenient access for future maintenance.

Callan to add its first TSHD

The Frederick Paup may not keep its “largest in the U.S.” title for long. Galveston, Texas, headquartered Callan Marine continues to expand its fleet. Last year, it released the tender package for a TSHD with a hopper capacity of 16,000 cubic yards. To be named the Admiral Nimitz, it will have an overall length of 422 feet and a breadth of 92 feet.

The diesel-electric powered dredge will have a maximum draft of 28.8 feet, a maximum dredging depth of 100 feet in the short dredge pipe configuration, and 130 feet in the long dredge pipe configuration. It will accommodate a crew of 28.

Currently the Callan fleet includes six cutter suction dredges of various sizes. Why add the TSHD?

“The Admiral Nimitz will be a robust, powerful addition to the capacity of the Callan fleet,” said Maxie McGuire, president of Callan Marine, when plans for the new TSHD were announced. “As the market continues to require maintenance dredging at an unprecedented rate, the Nimitz will allow Callan to respond quickly and efficiently to projects along the coast.

Insights into the evolving offshore market

The Biden administration’s just announced plans to jump-start U.S. offshore wind will generate a boom in demand for specialized Jones Act-compliant vessels and services. To help give you the insights needed to meet the needs of the new market, we have launched a new weekly newsletter, Marine Log Offshore.

Marine Log will also host a podcast and webcast series focusing on the latest in offshore wind farm development, policy and regulation and the implications for U.S. shipyards and vessel operators.

Crane Vessels Up Productivity

JMS provided complete engineering and design services for the new crane barges.

At the beginning of the year, JMS Naval Architects, Mystic, Conn., reported that the C&C Marine & Repair shipyard in Belle Chasse, La., had completed the construction of two 250-by -64-by-16-foot gantry crane barges—Weeks 537 and Weeks 539 — designed by JMS for Weeks Marine of Cranford, N.J.

JMS provided complete engineering and design services for the concept through detail design of the new crane barges to support both an existing Clyde Model 28 gantry crane and a new E-Crane 3000 series gantry crane.

The firm performed engineering calculations and developed design drawings in accordance with the requirements of the ABS Rules for Building and Classing Steel Barges.

JMS also developed a structural and systems design package, including generator and machinery arrangement, fuel, electrical, and hydraulic system one-lines, towing arrangements, crane rail and tiedown installation, drydocking and anode plan, and a construction details package.

Following installation of the E-crane, JMS developed weight change calculations and performed a deadweight survey to determine the lightship weight of the barge. Stability calculations were prepared and submitted to ABS for review and issuance of a load line certificate.

Hybrid Crane Vessel

And in February, the dredging and floating debris department of Amsterdam’s water utility, Waternet, took delivery of a Damen Crane Vessel 1804 WN25 from Damen Shipyards Hardinxveld.

Waternet does more than supply drinking water, it also processes wastewater and maintains water levels in Amsterdam’s waterways.

The 18-meter vessel is equipped to undertake a range of roles including detecting and removing garbage and abandoned derelict boats, as well as towing and pushing barges when required.

Designated the WN25, the crane vessel has been adapted to meet Waternet’s specific requirements. Its hull shape has been modified to reduce the suction effect when sailing close to the side of a channel and through bridges.

To minimize emissions, it has a hybrid propulsion system with lithium ion batteries installed in a dedicated air-conditioned section of the vessel, charged by an EU Stage 5 certificated engine. With a capacity of 138 kWh, the batteries give the vessel a maximum speed of 8 knots and a range of 3.5 hours at 6.5 knots, plus a bollard pull of 2.1 tonnes.

In addition, the wheelhouse has been redesigned, allowing it to be lowered in order to minimize the air draft and both it and the accommodation are also air-conditioned.

“While Waternet was already an existing customer of Damen Shipyards, having bought some Damen patrol vessels over the years, this latest contract was awarded to us via a European tender process that pitched our proposal against those from other leading shipbuilders,” said Jeroen van Woerkum, commercial manager at Damen Shipyards Hardinxveld. “We were of course delighted with the outcome.” Giant Crane Ship

The CMHI Haimen shipyard in China floated out Jan De Nul’s giant crane ship Les Alizés earlier this year.

Aimed at the offshore renewables and decommissioning market, it will be the largest heavy lift vessel in the Jan De Nul fleet, able to install super-large offshore wind components in floating conditions and with ultra-low emissions.

Main features of the vessel include a main crane of 5,000 tons, a deck loading capacity of 61,000 tons, and a deck space of 9,300 square meters.

Since the ship was ordered at the end of 2019, the design of Les Alizés has been further fine-tuned. Jan De Nul is investing in innovative mission equipment that provides solutions for the next generation offshore wind installation challenges while improving safety and efficiency.

As an ultra-low emission vessel, Les Alizés is equipped with a highly advanced dual exhaust filter system, removing up to 99% of nanoparticles from emissions using a diesel particulate filter (DPF) and reducing the NOx emissions and other pollutants by means of a selective catalytic reduction system (SCR) to levels in accordance with EU Stage V regulation. Les Alizés and Jan De Nul’s jack-up Voltaire will be the first two seagoing installation vessels in the world with extremely low emissions.

Les Alizés is due for delivery in the second half of this year.
