Did you know
- The MAN B&W G-type engine program, which includes the G70ME-C, was introduced to the market in October 2010 with the G80ME-C9 model. MAN Diesel & Turbo expanded the ultra-long-stroke program in May 2011 with the addition of the G70ME-C9 and other models. The G-type engines are based on the principles of the large-bore, Mark 9 engine series that MAN Diesel & Turbo introduced in 2006.
- The G70ME-C is part of MAN B&W's 'G-type' series, which are ultra-long-stroke engines. These engines are designed to operate at lower speeds, allowing for the use of larger, more efficient propellers, and are often chosen for vessels like bulk carriers and tankers. This contrasts with the 'S-type' engines, which also have a long stroke and low engine speed, and the 'K-type' engines, which have a shorter stroke and higher engine speed, traditionally used in larger container vessels.
- The G70ME-C is chosen for its ultra-long stroke design, which enables lower engine speeds and thus allows for larger, more efficient propellers. This design contributes to significant fuel consumption savings and reduced CO2 emissions, making it a highly efficient propulsion solution.
