ClassNK has issued an approval in principle (AiP) for a methanol fuel tank design concept developed by SRC Group. The certification demonstrates its feasibility from regulatory and safety perspectives.
ClassNK, along with IHI Corporation, JFE Steel, Tohoku University and the Institute of Science Tokyo, have been selected to work on tools assessing stress corrosion cracking (SCC) risks in ammonia fuel storage and transportation equipment.
Researchers analyzed the full lifecycle of several fuel options and found this approach has a comparable environmental impact, overall, to burning low-sulfur fuels.
