Japan, June 29 -- ClassNK and Japan's National Maritime Research Institute are moving to tackle one of the key technical risks facing future liquefied CO2 shipping, launching joint research on corrosion rates in low-temperature, low-pressure cargo tanks, according to ClassNK. The 29 June 2026 project targets a practical challenge for CO2 carriers as carbon capture, utilisation and storage moves closer to wider use: how to keep LCO2 tanks safe without forcing unnecessary cost into cargo purification, tank design and maintenance. ClassNK and NMRI, part of the National Institute of Maritime, Port and Aviation Technology, will study how trace impurities in CO2 cargoes affect corrosion.The focus includes water and SOx, or sulphur oxides, which c...
