South Korean engine builder Doosan Engine has successfully factory tested a 103,000hp MAN B&W 11G95ME-C9.5 two-stroke engine, the most powerful MAN engine ever built.

The engine is the first in a series of six bound for six 19,160 teu container ships ordered by Mediterranean Shipping Company (MSC). MAN Diesel & Turbo currently has orders for 28 of the engines, all for vessels serving the international container trade.

With a bore of 950mm and a stroke of 3,460mm, the MAN B&W 11G95ME-C9.5 provides a maximum continuous rating (at 100% engine power and speed) of 6,870kW per cylinder at 80 rpm and 21 bar MEP. The engine supplements MAN’s established S90ME-C9/10 engine types by allowing the engine to be further de-rated, thanks to the larger cylinder bore, which could allow fewer cylinders to be installed.

“The introduction of the G95ME-C9 was an important addition to MAN Diesel & Turbo’s G-engine programme,” the company noted. The first engine to leave Doosan in South Korea had its first start-up in October.
