The first electronically-controlled, gas-injection M-type engines (ME-GI) from MAN Diesel & Turbo have entered service onboard Qatari LNG partnership Nakilat’s Q-max vessel ‘Rasheeda’.

The retrofit, in which two MAN B&W S70ME-C diesel engines were converted to dual-fuel ME-GI engines, represents the first time low-speed marine diesel engines have been converted to use LNG as fuel. MAN PrimeServ and its partners conducted the conversion in June.

The 266,000m3 capacity LNG carrier, which was built in 2010, was converted at shipyard operator Nakilat-Keppel Offshore & Marine’s (N-KOM) Erhama bin Jaber Al Jalahma Shipyard in the Qatari port of Ras Laffan. The fuel supply system was provided by TGE.

Christian Ludwig, head of retrofit and upgrades, MAN PrimeServ, said: “There has been a remarkable partnership and cooperation through this historic conversion. Our ME-GI order book now stands at 140 orders – for different vessel sizes and applications, which we see as a compelling case for our technology to be designated the industry standard.”

Nakilat managing director Abdullah Al-Sulaiti added: “The success of the ME-GI project is the culmination of years of cooperation with Qatargas, RasGas [partners in Nakilat] and MAN Diesel & Turbo as turnkey project manager. In late 2013, Nakilat worked with our charterers to implement a pilot conversion on Q-Max Rasheeda. This is a milestone moment for all involved parties.”

MAN Diesel & Turbo reported that the vessel’s ME-GI units have displayed a seamless change between fuel-oil and gas operation.

The Qatar fleet comprises 14 Q-Max and 31 Q-Flex LNG carriers, all using dual MAN S70-ME low-speed diesel engines for propulsion.
