The MAN B&W G60ME-C engine

MAN Diesel & Turbo has signed a contract to supply four MAN B&W G60ME-C engines for four 113,000-dwt Long Range 2 (LR2) product tankers being built by STX Offshore & Shipbuilding for Teekay Tankers Ltd.

Ole Grøne, Senior Vice President Low Speed Sales and Promotions, MAN Diesel & Turbo, said: “In recent times, the market has sought to optimise propulsion efficiency through using larger propellers and lower-speed engines. Fuel optimisation has also become a priority. We find that large merchant vessels are compatible with larger-diameter propellers following an adaptation of the aft hull design, paving the way for higher efficiencies. The ultra-long-stroke G-type engine ably satisfies this trend.”

The tankers will be built at Jinhae shipyard in Changwon, South Korea, with delivery scheduled from the second half of 2015. The contract includes an option for up to an additional 12 vessels.

MAN Diesel & Turbo reports having close to 200 G-type engines on order, spread over a broad spectrum of applications, and says that it has the fastest market acceptance of any engine series in the MAN B&W portfolio.

The G-type entered into the market in October 2010 with the entry of the G80ME-C9 model. The company subsequently expanded the ultra-long-stroke programme in May 2011 with the addition of G70ME-C9, G60ME-C9, G50ME-B9, G45ME-B9 and G40ME-B9 models.

The G80’s longer stroke results in a lower rpm for the engine driving the propeller: a reduction from 78 rpm for the S80 engine to 68 rpm for the G80. This lower optimum engine speed allows the use of a larger propeller and is, ultimately, significantly more efficient in terms of engine propulsion. Together with an optimised engine design, this reduces fuel consumption and reduces CO2 emissions.

Meanwhile, MAN has announced that its latest G-type engine passed its Type Approval Test at HHI-EMD, the engine and machinery division of Hyundai Heavy Industries. The engine has been built for a tanker owned by Istanbul-based Densa Tankers and managed by Thome, the Singapore-based provider of global, integrated ship management services.
