Norwegian maritime system supplier Brunvoll has signed a contract with ship designer Vard Group for the delivery of an extensive propulsion and maneuvering system for Toyo Construction Co. Ltd new Cable Laying Vessel (CLV).
Toyo’s new vessel will have three azimuth propulsion thrusters in the aft of the vessel. The foreship of the vessel will have two tunnel thrusters and a retractable azimuth thruster. Furthermore, the vessel will feature Brunvoll’s control system for propulsion and...
The 31,000 cubic meter capacity “mega hopper” trailing suction hopper dredge (TSHD) ordered at Royal IHC by Royal Boskalis last year will be powered by three MAN 49/60 engines. This is the first marine application of MAN Energy Solutions’ most powerful diesel engine.
The MAN 49/60 successfully passed its type approval test in March 2023 and features a high power-per-cylinder of 1,300 kW, reducing the number of installed cylinders necessary to meet customer power demands. While in this particular...
Japan’s NYK Line has ordered MAN B&W ME-GA engines for four 174,000 cubic meter LNG carrier newbuilds. Each ship will have two 5G70ME-GA Mk. 10.5 engines and all eight engines will feature MAN Energy Solutions’ proprietary EGR BP (Exhaust Gas Recirculation ByPass) emissions-reduction technology.
“We developed this engine for easy application to most contemporary LNG carrier designs and, indeed, all ME-GA orders to date have been exclusively for this segment,” said Bjarne Foldager, head of...
Tampa, Fla., headquartered Overseas Shipholding Group Inc. (NYSE:OSG) has signed a contract with MAN Energy Solutions SE that will see all four of the nearly 20-year old OSG Alaska class tankers get a comprehensive lifecycle engine upgrade that will include making them ready for methanol fueling.
As we reported earlier, in October, OSG reached an agreement to purchase the fourth of the ships, Alaska Frontier, which had been in cold layup in Malaysia since 2019 and return it to service after a...
Norway’s Ulstein Verft AS has ordered two sets of three MAN 12V175D-MEV methanol ready engines for two CSOVs (commissioning service operation vessels) currently under construction for Bernhard Schulte Offshore (BS Offshore).
The 175D variable-speed gensets enable the vessels to achieve a significant reduction in fuel consumption and emissions. Each comes with an integrated MAN closed-loop SCR (selective catalytic reduction) system, a compact and flexible solution for the battery-hybrid vessels.

The U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) and Caterpillar Inc. have entered into a cooperative research and development agreement, or CRADA, to investigate marine methanol-fueled four-stroke engines.
While methanol has been much in focus as a fuel for large, two-stroke powered oceangoing vessels, the availability of methanol-fueled four=strokes could see its adoption across a broad range of vessel types. ORNL, which categorizes the marine industry as a...
COSCO Heavy Industry Shanghai Co. Ltd. has signed a contract with MAN Energy Solutions for the methanol retrofit of four main engines from COSCO Line 13,800 TEU Camellia class and 20,000 TEU Virgo class vessels. The vessels are currently powered by single-fuel MAN B&W 11S90ME-C10.5 engines that will be retrofitted to dual-fuel MAN B&W 11S90ME-LGIM10.5 units capable of operating on fuel-oil or methanol.
The ships will be the first vessels in COSCO’s fleet to sail on methanol.
The contract also...
Wärtsilä has brought to market the marine sector’s first four-stroke engine based solution for ammonia fuel. It is now commercially available as part of the Wärtsilä 25 engine platform, which was launched in September 2022. The first shipowner set to benefit from the ammonia-fueled four-stroke solution is Norway’s Viridis Bulk Carriers, the zero emission shipping partnership between Amon Maritime, Mosvolds Rederi and Navigare Logistics. Earlier this month, Wärtsilä and Viridis Bulk Carriers...

Not too surprisingly, the series of giant methanol-fueled car carriers that Wallenius Wilhelmsen is building in China (see earlier story) will be powered by MAN B&W ME-LGIM main engines. The Oslo-listed RO/RO specialist has now placed an order with MAN Energy Solutions for the engines for the first four ships, each of which will be powered by an MAN B&W 7S60ME-C10.5-LGIM (-liquid gas injection methanol) dual-fuel engine capable of running on green methanol.
The 9,300 CEU (Car Equivalent Unit)...
The California marine industry is to get easier access to renewable diesel. This has become increasingly important since California’s Commercial Harbor Craft (CHC) regulation, established by the California Air Resources Board (CARB), took effect on January 1, 2023. The regulation requires commercial harbor craft in the state to use renewable diesel (also known locally as R99 or R100) instead of ultra-low sulfur diesel (ULSD), to limit emissions such as particulate matter and nitrogen oxides for...
