Mitsubishi Shipbuilding Co. Ltd has held a christening ceremony for a next-generation LNG carrier, which is under construction for a joint venture of Mitsubishi Corp. and Nippon Yusen Kabushiki Kaisha (NYK Line). The ship, named ‘Diamond Gas Orchid’, is the first Sayaringo STaGE (Steam Turbine and Gas Engines) type vessel, which brings improvements in both carrying capacity and fuel performance thanks to a more efficient hull structure and an innovative hybrid propulsion system. Upon completion in late June, the Diamond Gas Orchid will go into service, transporting LNG for the Cameron LNG Project (a project in Louisiana, US, in which Mitsubishi Corp. and NYK Line are participating.
The christening ceremony was held at the main plant of MHI's Nagasaki Shipyard & Machinery Works.
The Diamond Gas Orchid features LOA (overall length) of 293.5 m, width of 48.94 m, depth of 27 m, and draft of 11.05 m. Deadweight capacity is approximately 73 800 t, and the total holding capacity of the tanks is 165 000 m3. Launching took place in March 2017. Construction was performed by Mitsubishi Heavy Industries Marine Structure Co. Ltd, a MHI Group company.
STaGE is a hybrid propulsion system, combining a steam turbine and engines that can be fired by gas. Efficient use of the engines' waste heat in the steam turbine results in substantial improvement in plant efficiency, enabling high-efficiency navigation throughout a full range of speeds.
