MAN Diesel & Turbo has been selected to provide a complete propulsion package and fuel-gas system for the world’s first fishing vessel with LNG propulsion, the company said in its press release. A 86-metre newbuilding purse-seiner, the ‘Libas’ will be built by Cemre Shipyard in Istanbul. It will feature a MAN 6L51/60DF main engine, Renk gearbox, MAN Alpha propeller system and MAN Cryo LNG fuel-gas system with a 350 m3 tank. Liegruppen, the Norwegian fishing group, has ordered the vessel, while compatriot, Salt Ship Design, has provided the design.
The delivery of the new LNG-propulsion package is part of MAN’s wide ranging engagement for the establishment of LNG as a shipping fuel. Calling for a ‘Maritime Energy Transition’ the company considers the use of natural gases as the fuels of choice in global shipping as the most promising way to supporting the goal of a climate-neutral shipping industry. Launched in 2016 after COP 21, MAN’s initiative has since found broad support within the shipping industry and politics.
The scope of the MAN Cryo fuel-gas system covers:
• 350 m3 vacuum insulated cylindrical type C tank
• TCS/coldbox with process equipment, manifold and instrumentation
• emergency shut-down system • bunker station for supply of LNG to tank.
The system is designed for a net tank volume of 330 m3 of LNG and temperatures down to minus 163 °C. The tank stores LNG at the lowest possible temperature and pressure until it is evaporated and supplied to the dual-fuel MAN 6L51/60DF main engine, as consumption demands.
The uprated MAN L51/60DF MAN Diesel & Turbo’s uprated MAN L51/60DF engine successfully passed its Type Approval Test at the end of 2017 where a nine-cylinder test engine had an output of 1,150 kW/cylinder at a nominal speed of 500/514 rpm. The engine can be employed both as marine main-engine and auxiliary engine and ran on both fuel-oil (DMA) and natural gas on the testbed.
