As the marine industry collectively pushes toward decarbonization, there are seemingly daily 'world firsts' as owners, designers, builders and suppliers alike conspire to deliver innovative solutions to reducing marine emissions.
MAN Diesel & Turbo was picked to provide a complete propulsion package and fuel-gas system for the world’s first fishing vessel with LNG propulsion, an 86-m newbuild purse-seiner dubbed ‘Libas’ to be built by Cemre Shipyard in Istanbul. Libas will feature a MAN 6L51/60DF main engine, Renk gearbox, MAN Alpha propeller system and MAN Cryo LNG fuel-gas system with a 350 cu. m. tank. Liegruppen, the Norwegian fishing group, has ordered the vessel, while compatriot, Salt Ship Design, has provided the design.
“This is a pioneering project," said Wayne Jones, Chief Sales Officer, MAN Diesel & Turbo. "At MAN we are convinced that low-emission gas fuels are the silver bullet to decarbonizing the shipping industry."
Calling for a ‘Maritime Energy Transition’ MAN D&T 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.
In 2015 MAN Diesel & Turbo has purchased and fully integrated the fuel gas specialist Cryo AB. Under the brand MAN Cryo, the company has since then offered systems for the storage, distribution and handling of liquefied gases.
The scope of the MAN Cryo fuel-gas system covers:
• 350 cu. m. 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 cu. m. 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.
