JUNE 24, 2016 — The largest and most powerful engine ever from MAN Diesel & Turbo has entered service.

Built by Doosan Engine in Korea and rated at 75,570 kW (103,000 horsepower), the engine is an MAN B&W 11G95ME-C9.5 two-stroke type that acts as prime mover in the 19,437 TEU containership MSC Jade, recently delivered to Mediterranean Shipping Company by Daewoo Shipbuilding and Marine Engineering (DSME).

The MSC Jade also features four MAN L32/40 auxiliary engines (2 × 8L32/40 + 2 × 9L32/40 units), each with a single MAN NR34/S turbocharger.

Doosan Engine reported the main engine’s initial start during October 2015 and a successful shop-test subsequently followed.

The engine is the first for a series of six containerships ordered by MSC, with a second sister-vessel to MSC Jade shortly scheduled for sea trials and two further vessels, currently finishing construction at  shipbuilder Samsung Heavy Industries, due for sea trials during June.

“We attribute the G95’s popularity in this segment to its ability to provide sufficient power for such vessels to reliably achieve their desired operating speed,” said Ole Grøne, Senior Vice President Low-Speed Sales and Promotions, MAN Diesel & Turbo. “Here, the G95’s rpm ensures that a propeller of optimal size can be employed, in turn delivering a low fuel-oil consumption for an optimal fuel economy.”

MAN Diesel & Turbo reports that, since August 2013, sixty-eight G95 engines, in 8- to 11-cylinder versions, have been selected for the “large” capacity container market — containerships ranging in size from 9,000 to 21,000 TEU.

The G95ME-C9 itself is an important part of MAN Diesel & Turbo’s G-engine program. With a bore of 950 mm and a stroke of 3,460 mm, it delivers 6,870 kW/cylinder at 80 rpm and 21 bar MEP (in L1) and was introduced as a supplement to the successful S90ME-C9/10 engine types, allowing the engine to be further de-rated thanks to the larger cylinder bore and/or fewer cylinders to be installed.

Following this trend, as well as those for cost-down and downsizing, the S90ME-C has recently been supplemented with a G90ME-C10 version.
