Mitsubishi Heavy Industries said today it has agreed to build two new-generation liquefied natural gas (LNG) carriers to be jointly owned by Osaka Gas Co., Ltd., and Mitsui O.S.K. Lines. The deal marks the first construction of the “Sayaendo” Series, a series said to significantly improves fuel consumption and maintainability. Each 75,000dwt LNG carriers will be capable of carrying up to 153,000 m3 of LNG.
The Sayaendo features a peapod-shaped continuous cover for the Moss spherical tanks, integrated with the ship’s hull, in lieu of a conventional hemispherical cover and enables greater structural efficiency and size and weight reductions, maintaining the ship’s overall strength. The continuous cover over the tanks improves aerodynamics by substantially reducing wind pressure, which serves as drag on ship propulsion. For its main power plant, the Sayaendo adopts MHI’s “Ultra Steam Turbine Plant” (UST), a new turbine plant which achieves higher thermal efficiency through effective use of thermal energy by reheating steam. Together with downsizing, weight reduction and hull line improvement, the new ship achieves a substantial 20% reduction in fuel consumption compared to conventional ships.
Osaka Gas International Transport is a wholly owned subsidiary of Osaka Gas. The two LNG carriers to be delivered by MHI will be jointly owned by Osaka Gas International Transport and Mitsui O.S.K. Lines, Ltd., which will function as the ship management company. Both ships are planned to be used for transportation of LNG procured by Osaka Gas.
Two LNG carriers are slated for delivery in 2014 and 2015, respectively.
