New standards coming for liquefied hydrogen marine transfer

摘要

Global standards that are being developed for marine loading arms (MLAs) and cryogenic hoses for import, export and bunkering of potentially hazardous liquefied gases were the topic of discussion at Riviera Maritime Media's New twists on marine loading arms and hoses webinar. Oil Companies International Marine Forum (OCIMF) engineering adviser Ricardo Martinez said he expects a standard for liquefied hydrogen (LH2) to be published in 2022, under International Standard Organisation standard ISO/CD 24132 for ships and marine technology. The new standards will cover design and testing of marine transfer arms for LH2. The arms are on the cutting edge of technology for marine transfer of cryogenic gas and developing safety and quality standards for equipment involved in LH2 transfer poses new challenges for the sector. In particular, transfer operations between terminals and ships are tricky procedures, due to the need for LH2 to be kept at -250℃, as Mr Martinez explained. ISO is working on standards for liquefied hydrogen marine transfer arms just as the first test project is being developed to transport the gas from Australia to Japan.
