- The next-generation LNG carrier with improved carrying capacity and fuel performance, currently under construction for Mitsubishi Corporation and NYK Line was christened.
- “Diamond Gas Sakura” is the third “Sayaringo STaGE” type vessel for both companies, and was launched on September 15, 2018.
- It has a length of 293.5m, width of 48.94m, and depth of 27.0m, with a draft of 11.05m.
- Its deadweight tonnage is approx 73,800 tonnes, tank holding capacity of 165,000m3.
- STaGE is a hybrid propulsion system combining a steam turbine and gas-fired engines.
- Utilization of waste heat from the engines for the steam turbine provides improvement in plant efficiency, allowing high-efficiency navigation in both low and high-speed areas.
Mitsubishi Shipbuilding Co., Ltd., a Group company of Mitsubishi Heavy Industries, Ltd. (MHI) based in Yokohama, christened a next-generation “Sayaringo STaGE” LNG carrier, the Diamond Gas Sakura, reports APN News.
The third next-generation vessel
The next-generation LNG (liquefied natural gas) carrier is currently under construction for Mitsubishi Corporation and Nippon Yusen Kabushiki Kaisha (NYK Line).
The christening ceremony, held at MHI’s Nagasaki Shipyard & Machinery Works, was attended by representatives of the ship owner and many others involved with the project.
Toho Gas Co., Ltd. President and Representative Director Yoshiro Tominari, and Tohoku Electric Power Co., Inc. Director & Managing Executive Officer Toshinori Abe, announced the name of the new ship “Diamond Gas Sakura”. This ship is the third “Sayaringo STaGE” type vessel for the two companies.
What is new in this carrier?
The newest model of LNG carrier has significantly improved carrying capacity and fuel performance with the adoption of a more efficient hull structure and hybrid propulsion system.
After completion and handover in May, the Diamond GasSakura will join their first two ships, the Diamond Gas Orchid and Diamond Gas Rose, in transporting LNG for the Cameron LNG Project.
About the new carrier and the joint venture
The Diamond Gas Sakura whose launching took place on September 15, 2018, has a length of 293.5m, width of 48.94m, and depth of 27.0m, with a draft of 11.05m.
Deadweight tonnage is approximately 73,800 tonnes, with a total tank holding capacity of 165,000m3.
Mitsubishi Shipbuilding received the order for the new vessel through MI LNG Company, Limited, a joint venture for the design and sale of LNG carriers established by MHI and Imabari Shipbuilding Co., Ltd. Construction was managed by Mitsubishi Heavy Industries Marine Structure Co., Ltd., an MHI Group company based in Nagasaki.
About the successor vessel
The Sayaringo STaGE is a successor to the “Sayaendo,” a vessel highly acclaimed for its highly reliable and innovatively refined MOSS-type spherical tanks.
The use of apple-shaped tanks allows for greater LNG carrying capacity without increases to the ship’s beam, while the hybrid propulsion system further improves fuel efficiency over the previous model.
Waste heat from the engines for the steam turbine?
STaGE, an acronym derived from “Steam Turbine and Gas Engines,” is a hybrid propulsion system combining a steam turbine and gas-fired engines.
Effective utilization of waste heat from the engines for the steam turbine provides a substantial improvement in plant efficiency, allowing for high-efficiency navigation in both low and high-speed areas.
Going forward, Mitsubishi Shipbuilding and MHI Marine Structure will continue the development of next-generation LNG carriers exhibiting exceptional fuel efficiency and sustainability, to further advance contributions to stable energy supplies and environmental conservation.
