- LNG carrier with capacity of 177,000 m3 under construction for Mitsui & Co christened.
- Mitsubishi Shipbuilding bagged the order for the new vessel through MI LNG Company, a joint venture for the design and sale of LNG carriers.
- The vessel’s tank design effectively expands the ship’s LNG carrying capacity without increasing its width, and allows it to pass through the expanded Panama Canal.
- The propulsion system is a hybrid 2-shaft STaGE system combining a steam turbine and a gas-fired engine.
- Use of waste heat by the UST allows high-efficiency navigation at both low and high speeds.
Japan’s Mitsubishi Shipbuilding Co held a christening ceremony for Marvel Crane, the first of two LNG carriers under construction, writes John Snyder for LNG World Shipping.
The ceremony
The christening ceremony was held on 21 February for Marvel Crane, the first of two LNG carriers with capacities of 177,000 m3 under construction for Mitsui & Co.
Once completed in March 2019, Marvel Crane will transport LNG for the Cameron LNG Project in the US. Mitsui & Co is a partner in the Cameron LNG project.
Marvel Crane has a length overall of 293 m, width of 49 m and depth of 27 m, with a draught of 11 m.
The joint venture
Mitsubishi Shipbuilding received the order for the new vessel through MI LNG Company, a joint venture for the design and sale of LNG carriers established by MHI and Imabari Shipbuilding Co.
Construction was managed by Mitsubishi Heavy Industries Marine Structure Co, an MHI Group company based in Nagasaki.
What is new in the design?
The vessel is equipped with a modified version of the highly reliable 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 expanded Panama Canal.
Offers high-efficiency navigation
The propulsion system is a hybrid 2-shaft STaGE 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 able to burn both natural gas and diesel, as well as an electric propulsion engine.
Effective utilisation of waste heat by the UST provides a substantial improvement in plant efficiency, allowing for high-efficiency navigation at both low and high speeds.
