Fukui Seisakusho (FUKUI) and ClassNK have signed a Memorandum of Understanding (MoU) concerning a joint study on a safety relief valve for a cargo tank of liquefied hydrogen carriers.
ccording to ClassNK, in order to ensure safety in the transport of liquefied hydrogen, the development of safety relief valves that can handle hydrogen’s characteristics including extremely low temperatures, ease of leakage, and hydrogen embrittlement, which leads to a decrease in material strength and toughness, is necessary.
Appropriate safety standards are also required. As part of the efforts to establish key technologies for hydrogen transport, FUKUI and ClassNK have agreed to jointly conduct a study for the installation of safety relief valves for cargo tanks of liquefied hydrogen carriers on actual ships.
For the hydrogen supply chain, it is crucial to have the commitment and the ability to execute to overcome various challenges such as extremely low temperatures and hydrogen embrittlement.
… said Yo Fukui, President and CEO, FUKUI
ClassNK has recently been showing interest in hydrogen carriers as in late July, it issued an Approval in Principle (AiP) for a Cargo Containment System (CCS) and Cargo Handling System (CHS) for liquefied hydrogen carrier developed by GTT.
Masaki Matsunaga, Corporate Officer/Director of Plan Approval and Technical Solution Division of ClassNK had then stated that ClassNK is anticipating hat hydrogen transportation will play a significant role in a decarbonized society.
Through our extensive experience with liquefied hydrogen carriers, we will apply our expertise to advance the development and standard relevant to the technology, thereby supporting the global adoption of liquified hydrogen carriers.
