Dual-fuel gas injection marine diesel engines gain popularity with LNG carrier operators, confirmed, say MAN Diesel & Turbo (MDT) by a recent order from Teekay Corporation for two 173,400 cubic metre capacity LNG carriers to be powered by ‘M’-type, electronically controlled, gas injection (ME-GI) 5G70 engines. A contract option with builders, Daewoo Shipbuilding & Marine Engineering (DSME) of South Korea, allows for three more of the same large ships.Unveiled at a major event at MDT’s Copenhagen Diesel Research Centre last year, the ME-GI engine represents the culmination of many years’ work that began in the 1990s with the company’s prototype MC-GI dual-fuel engine that entered service at a power plant in Chiba, near Tokyo, Japan in 1994.

Mitsubishi Heavy Industries (MHI) signed on the dotted line a few days ago to build a 138,000 gt LNG carrier in their ‘Sayaendo’ series for Mitsui O.S.K. Lines . MHI describe this 288m (945ft) long vessel as a ‘New-generation’ LNG carrier, with a multitude of new design features which add up, MHI claims, to deliver a 25% reduction in fuel consumption compared to that of conventional LNG carriers of the same size; but essentially the design is marked by two outstanding features. The first a dramatic change in the shape of the ship compared with the distinctive dromedary-like silhouette of other LNG carriers. Second a new turbine plant that achieves higher thermal energy by steam reheat.
