Description:
A project to import a large amount of liquid hydrogen (LH 2 ) from Australia by a cargo carrier, which is equipped with two 1250 m 3 tanks, is underway in Japan. It is important to understand sloshing and boil-off characteristics inside the LH 2 tank during marine transportation. However, the LH 2 sloshing and boil-off characteristics on the sea have not yet been clarified. First experiment on the LH 2 transportation of 20 liter with magnesium diboride (MgB 2 ) level sensors by the training ship “Fukae-maru”, which has 50 m long and 449 ton gross weight, was carried out successfully inside Osaka bay on February 2, 2017. In the experiment, synchronous measurements of liquid level, temperature, pressure, ship motions, and accelerations as well as the rapid depressurization test were done. The increase rate of the temperature and the pressure inside the LH 2 tank were discussed under the rolling and the pitching co...
