Did you know
- The MAN B&W ME-GI engine, a gas-injection, dual-fuel, low-speed diesel engine, was first publicly demonstrated in May 2011, building upon years of research and development that began in the 1990s with a prototype MC-GI dual-fuel engine. The S90ME-C9.2, a super-long-stroke, 90-cm bore Mk 9 engine, completed test bed trials in July 2012.
- The S90ME-GI is part of MAN B&W's ME-GI series, which are electronically controlled, two-stroke, dual-fuel engines. It is a larger bore option within the ME-GI family, designed to offer high efficiency and fuel flexibility.
- This model is chosen for its ability to operate on multiple fuels, including LNG, heavy fuel oil (HFO), and marine diesel oil (MDO), offering flexibility in response to fuel prices and environmental regulations. It is also recognized for its high thermal efficiency and low methane slip when operating on gas.
