Mitsubishi Shipbuilding has held a christening ceremony, at the Koyagi Plant of MHI's Nagasaki Shipyard & Machinery Works, for a next-generation LNG carrier currently under construction for Mitsui & Co.

The new ship, named Marvel Crane, is designed for significant improvements in both LNG carrying capacity and fuel performance due to the adoption of a more efficient hull structure and hybrid propulsion system. Completion is scheduled for March 2019, after which the Marvel Crane will be put into service, transporting LNG for the Cameron LNG Project in the US.

Marvel Crane is the first of two LNG carriers of the same design being constructed for Mitsui. It has a length of 293.0m, width of 48.94m, and depth of 27.5m, with a draught of 11.4m. Deadweight tonnage is approximately 79,000 tons, with a total tank holding capacity of 177,000m3.

The vessel is equipped with a modified version of the Moss spherical tank, an apple-shaped tank with a protruding upper half. This tank design effectively expands the ship's LNG carrying capacity without increasing its width, allowing it to pass through the new Panama Canal. The propulsion system is a hybrid two-shaft STaGE (Steam Turbine and Gas Engines) system combining a steam turbine and a gas-fired engine. The ship is equipped with MHI's proprietary high-efficiency reheat marine steam turbine engine, or UST (MHI Ultra Steam Turbine Plant), a dual-fuel engine power generator that is able to burn both natural gas and diesel, as well as an electric propulsion engine. Effective use of waste heat by the UST provides a substantial improvement in plant efficiency, allowing for high-efficiency navigation at both low and high-speeds.
