The American Bureau of Shipping (ABS) has awarded approval in principle (AiP) to two new liquid carbon dioxide (CO2) carrier designs developed by a Japanese consortium.
Each of the awarded carriers has Type-C cargo tanks made of carbon manganese steel that stows the liquefied CO2 at low temperature and low pressure.
One tank is a 50,000 cubic meter carrier, and the other is a 23,000 cubic meter carrier. ABS reviewed the drawings based on class and statutory requirements for the designs.
Mitsubishi Shipbuilding, Nihon Shipyard, Kawasaki Kisen Kaisha, Mitsui O.S.K. Lines, Nippon Yusen Kabushiki Kaisha, Mitsui & Co, and Mitsubishi Corporation worked together to develop the carriers.
The consortium was issued AiP at Gastech 2024 in Houston.
John McDonald, President and Chief Operating Officer of ABS, 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.”
Liquid CO2 carriers transport liquefied CO2 at low temperatures and high pressures to the location of storage or use. The carriers are considered an economical option for transporting CO2 produced at industrial facilities.
Various shipowners, shipbuilders, and design houses are currently developing designs for larger liquid CO2 carriers globally.
ABS has also awarded AiP to Nikkiso Clean Energy & Industrial Gases’ ammonia fuel supply system recently.
Nikkiso’s awarded ammonia fuel supply system has high-efficiency pumps and an integrated fuel management system. It can be installed in marine applications such as merchant ships.
