ABS issued an approval in principle (AIP) to pioneering Japanese companies at Gastech 2024 for two liquid carbon dioxide (LCO2) carrier designs with Type-C cargo tanks that do not require performing post-weld-heat-treatment 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 50K cubic metre carrier and a 23K cubic metre carrier, featuring Type-C cylindrical tanks made of carbon manganese steel that stows the liquefied CO2 with low-temperature and low-pressure.
LCO2 critical characteristics
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 Co., Ltd.; Nihon Shipyard Co., Ltd.; Kawasaki Kisen Kaisha, Ltd.; Mitsui O.S.K. Lines, Ltd.; Nippon Yusen Kabushiki Kaisha; Mitsui & Co., Ltd.; and Mitsubishi Corporation.
Decarbonisation and sustainability solutions
“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 pioneering classification society for gas carriers to support this sector of the global energy transition,” said John McDonald, ABS President and COO.
ABS is the world’s premier classification society for gas carriers with more than 50 years of experience, and ABS is pioneering the maritime industry in comprehensive decarbonisation and sustainability solutions.
