The planned operation of natural gas liquefaction units offshore has raised many new safety issues. Cryogenic spillage is among the most critical as load bearing structures cannot be designed to resist such accidents.

In order to propose better protection at manageable cost, to enhance structural integrity and to lower the risks associated with cryogenic spillage on marine structures, TechnipFMC as FLNG market leader, has run an extensive physical test program to support the development of tailor made numerical modeling tools.

In a first step, numerous protective materials were screened and then tested to assess their performances. We found that all products currently available in the market display limitations. During the test campaign, alternate product designs were investigated to improve structural design and avoid the need for human intervention “Inspection Maintenance and Repair” during service lifetime.

In this paper, a summary of the test campaign and a complete introduction of Series of standard of ISO 20088 will be provided.
