The World's First Liquefied Hydrogen Transport Ship Successfully Carries Liquefied Hydrogen Storage Tanks

- Mar 13, 2020-

According to the official website of Kawasaki heavy industry, on March 7, the world's first liquefied hydrogen transport ship "Suso front" built by Kawasaki heavy industry completed the hoisting of liquefied hydrogen storage tanks in its grinding plant. Subsequently, the ship will be installed and outfitted in Kobe factory of Kawasaki heavy industries, and the sea trial will be officially started after completion in October 2020. The ship is expected to be put into trial operation in the next fiscal year, bringing liquefied hydrogen made in Australia to Japan.


The Suso front was launched in December 2019, with a total length of 116 meters, a width of 19 meters, a depth of 10.6 meters, a draft of 4.5 meters, a gross tonnage of 8000 tons and a speed of 13 knots. The oval liquefied hydrogen storage tank installed this time is 25 meters long and 16 meters high, which can store 1250 cubic meters of liquefied hydrogen. The tank adopts the vacuum insulated double shell structure, and uses the technical experience of land liquefied hydrogen tank and liquefied natural gas tank for reference to achieve high strength and high insulation performance.


It is understood that Japan is cooperating with Australia to build the world's first sea transportation line of liquefied hydrogen from Australia to Kobe, Japan, about 9000 kilometers. The project cools the hydrogen generated from Australian lignite to - 253 ℃ to produce liquefied hydrogen, then compresses the volume to 1 / 800, and then transports it to Japan by specially designed and built liquefied hydrogen transport ship. The key of the whole project is the construction quality of liquefied hydrogen transport ship and liquefied hydrogen storage tank. Based on the experience of LNG ship design and construction, Kawasaki heavy industry began to research and develop the special liquefied hydrogen transport ship and liquefied hydrogen storage system in 2014. In 2016, the company, together with a number of Japanese enterprises, jointly established a carbon dioxide free hydrogen energy supply chain technology research association to jointly tackle hydrogen production, transportation, storage and use technologies, breaking through the "bottleneck" of related technologies. During the design and construction of "suis front", Kawasaki heavy industry adopted the design of vacuum dome, double-layer stainless steel heat insulation shell, heat insulation support structure, etc., and optimized the design of the diesel electric propulsion system, ventilation pipeline, deck machinery monitoring, cabin equipment control, etc. in terms of the characteristics of liquefied hydrogen transportation.
