Qatari shipyard Nakilat Keppel Offshore & Marine Ltd and Qatari LNG producers Qatargas and RasGas Company Limited will work with MAN Diesel and Turbo (MDT) to carry out what is believed to be the world’s first conversion of a low-speed diesel engine to use Liquefied Natural Gas (LNG) as an alternative fuel. The conversion of the Q-Max vessel will be carried out under a contract between TGE Marine Gas Engineering and MDT.

The modification of the 2-stroke main engine will make use of MDT’s ME-GI (M-type electronically controlled gas injection) system. The use of ME-GI delivers cleaner fuel technology with a significant reduction in environmental emissions and added benefits of reduced maintenance and flexibility to respond to market changes.

The conversion of the ship shall take place at the Nakilat Keppel Offshore & Marine facilities in Qatar’s Port of Ras Laffan. Once converted and put into operation the ship will be propelled by the world’s first low speed diesel engine running on LNG onboard a ship.

TGE Marine has intensively investigated the design of the high pressure fuel gas supply system with its California, U.S. partner ACD for the pumping and vaporizing system, including a complete dynamic simulation of the system considering all load scenarios. TGE Marine’s scope of delivery includes a modular pre-fabricated fuel gas skid, which is scheduled for delivery in Q1, 2015.

TGE Marine’s CEO, Manfred Küver, commented: “We are extremely pleased to have been selected by MDT as partner for its first conversion contract for one of the largest LNG-carriers in the market. This prestigious project is certainly a signal for the market that the MAN 2-stroke ME-GI solution is one of the most economic approaches of a modern LNG carrier design.

A Q-Max vessel is a membrane type liquefied natural gas carrier. The name is derived from Q – Qatar and “Max”  – the maximum size of ship able to dock at the LNG terminals in Qatar.
