ClassNK<\/a> have signed an MOU (Memorandum of Understanding) for joint consideration of ultra-high pressure safety relief valves designed for the use in hydrogen dual-fuel engines, and hosted a signing ceremony at the 'Gastech 2025' exhibition being held in Milan, Italy.<\/p>\nBoth parties agreed in 2023 to jointly conduct study for installation of safety relief valves for cargo tanks of liquefied hydrogen carriers on actual ships, and signed a MOU in 'Gastech 2023'*. As a result of this study, a type approval certificate for the PILOT-type low pressure safety relief valve (PSL-MD type) was issued this year.<\/p>\n
Based on this achievement, they have now agreed to carry out joint consideration of ultra-high pressure safety relief valves for hydrogen dual-fuel engines that can meet advanced technical requirements (material resistance to hydrogen embrittlement, sealing performance, etc.) needed for hydrogen fuel supply systems.<\/p>\n
The roles of each party are as follows.<\/p>\n
Fukui: <\/strong>Development of RPS-type (high pressure compatible) safety relief valves for hydrogen dual-fuel engines
\nClassNK:<\/strong> Review of the valves based on prescribed rules upon receiving an application for type approval<\/p>\nThrough this collaboration under the MOU, both parties will contribute to the social implementation of propulsion systems using hydrogen as a fuel.<\/p>\n
