Abstract
<p>To develop a loading arm for ship-to-shore transfer of liquefied hydrogen, an emergency release system (ERS) for liquefied hydrogen has been designed and manufactured. In order to estimate its mechanical and thermal behaviors, we have developed a calculation model for temperature and stress distribution of the ERS at low temperatures during the transfer of liquefied hydrogen. The calculation has revealed that the surface temperature would exceed the boiling point of oxygen. A prototype model of the designed ERS has been manufactured and tested by filling liquid hydrogen in the model. The temperature and strain on the surface have been measured during the test and compared with the calculation results. The results have shown that the calculation can predict the temperature on the surface of ERS and that the designed ERS can avoid generating liquefied oxygen. It has also been shown that the measured strains are well consistent with the predicted strain on the surface of ERS. It has been demonstrated that the developed ERS exhibits performance good enough to be utilized for the loading arm for transfer of liquefied hydrogen. </p>
