For VLCCs, it is estimated that the application of a 7G80ME-C will prompt an overall efficiency increase of 4-5%, compared with a 7S80ME-C9 or an alternative engine design with the same engine speed. G-type promises lower rpm with significant fuel and CO2 reductions of up to 7% as part of propulsion package. [More]

A new series of super-long-stroke low-speed engines designated G type is announced by MAN Diesel &Turbo. The first series offered is the G80ME-C9 with a bore of 800mm and stroke of 3,720 mm. The G80ME-C9 will be offered in six, seven, eight and nine cylinder configurations. The slower running engines offer the use of larger propeller diameters with the associated improved efficiency improvement.Design work on the first G type is making good progress and final drawings are expected to be completed by mid 2011. Other G type series will follow in the future according to demand. [More]
