ABS issued an approval in principle (AIP) to a consortium of Japanese companies for two liquid carbon dioxide (LCO2) carrier designs with Type-C cargo tanks that do not require performing post-weld-heat-treatment.
The AiP is based on the demonstration of an engineering critical assessment (ECA). ABS reviewed the drawings based on class and statutory requirements for the two designs, a 50,000m3 carrier and a 23,000m3 carrier, featuring Type-C cylindrical tanks made of carbon manganese steel that stows the liquefied CO2 with low-temperature and low-pressure.
This AIP is the result of extensive cooperation within a joint development project on the detailed design development, considering LCO2 critical characteristics. The project team included Mitsubishi Shipbuilding; Nihon Shipyard; Kawasaki Kisen Kaisha; Mitsui OSK Lines; Nippon Yusen Kabushiki Kaisha; Mitsui; and Mitsubishi Corporation.
John McDonald, ABS President and COO said: “The safe transportation of CO2 plays a vital role in the carbon value chain, and ABS is proud to use our expertise as the world’s leading classification society for gas carriers to support this sector of the global energy transition.”
