The new ship, named “Nohshu Maru,” is the fourth vessel of the latest model “Sayaringo STaGE” type, featuring significant improvements in both LNG carrying capacity and fuel performance due to the adoption of a more efficient hull structure and an innovative hybrid propulsion system. Completion and delivery is scheduled for February, after which the “Nohshu Maru” will be put into service, transporting LNG for the Freeport LNG Project in the U.S. state of Texas (in which Jera is participating), among other ventures.
The “Nohshu Maru” has a length of 297.5 meters, width of 48.94 meters, and depth of 27.0 meters, with a draft of 11.1 meters. Deadweight tonnage is approximately 80,300 tons, with total tank holding capacity of 180,000 cubic meters. Launching took place on Oct. 9, 2017.
Mitsubishi Shipbuilding received the order for the new vessel from the owner, Trans Pacific Shipping 5 Ltd. through MI LNG Company, 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. The vessel’s name is derived from the old provincial name for the southern region of Gifu Prefecture, one of the areas served by Chubu Electric Power.
Jera was established in 2015 as an equal-share joint venture between TEPCO Fuel & Power, a group company of Tokyo Electric Power Company, and Chubu Electric Power Company. Its business operations include construction and refurbishment of thermal power plants in Japan, as well as energy infrastructure projects and power generation overseas.
The Sayaringo STaGE is a successor to the “Sayaendo,” a vessel highly acclaimed for its reliability 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 width, while the hybrid propulsion system further improves fuel efficiency over the previous model.
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.
