Hydrogen-powered feeder container vessels to be equipped with MAN 175D gensets for back-up diesel-electric propulsion

Cochin Shipyard Ltd (CSL), the largest shipbuilding and maintenance facility in India, has ordered 2 × 2 × MAN 12V175D-MEV variable-speed GenSets in connection with the building of two short-sea hydrogen-fueled feeder container ships for global logistics company, Samskip Group, headquartered in Rotterdam. (Earlier post.)

Known as the SeaShuttle project, the vessels will be among the first of their kind globally to be powered by individual 3.2 MW hydrogen fuel-cell-based energy systems. The MAN GenSets will act as a back-up, forming a diesel-electric propulsion plant with a permanent magnet generator.

The 135-meter, 500 teu ships are due for delivery in Q3 and Q4 of 2025, respectively, and will operate between Oslo Fjord and Rotterdam, a distance of approximately 700 nautical miles. They will furthermore be capable of being remotely controlled and come autonomous-ready.

The 175D is a variable-speed GenSet with high efficiency, even at low loads, inherent fuel efficiency and low emissions. As the engine with the lowest total cost of ownership in the market, the high-speed engines will each come integrated with compact, flexible and closed-loop MAN SCR (Selective Catalytic Reduction) systems. The engines are capable of running on bio-fuels such as HVO and B100.

MAN Energy Solutions states that the engines have the lowest lube-oil consumption on the market with long oil-change intervals and best-in-class times-between-overhauls (TBOs).


MAN 175D engine. MAN Energy Solutions has developed the MAN 175D engine range to supplement and complete its product portfolio in the maritime sector. Available in three variants of 12-, 16- and 20-cylinders, the engine is available with an output ranging from 1,500 to 4,400 Kilowatts and is optimized for propelling ferries, offshore support ships, tugs and other working vessels. Other market areas, such as superyachts, planing yachts and naval marine applications are also served by additional engine variants.
