Maritime classification society American Bureau of Shipping (ABS), Hyundai Heavy Industries Group (HHI) and the Republic of the Marshall Islands (RMI) Maritime Administrator have collaborated on the development of a next-generation ultra-large liquefied carbon dioxide (LCO₂) carrier.

With a 74,000cm³ design, the vessel is claimed to have the world’s largest LCO₂ capacity and will build on the 40,000cm³ ‘super gap’ technology developed last year by HHI.

ABS will verify the design of the new LCO₂ carrier to approve the basic design, and RMI Maritime Administrator will be engaged in the design acceptance and equivalent arrangements of the vessel.

HHI Group previously secured approval in principle (AIP) from ABS for its carbon dioxide injection platform, developed for the storage of carbon dioxide that was captured on land.

The carbon dioxide is later liquefied at high pressure and shipped to the sea through a carrier or pipeline.

The new platform was developed by HHI to store 400,000 tonnes of carbon dioxide underground in Korea’s East Sea gas field, which will commence operation in 2025. 

ABS chairman, president and CEO Christopher Wiernicki said: “ABS has been working across the technology needed to enable the carbon value chain with HHI, and now, following the advances on the carbon capture platform, we are working on the vessels which will play such a critical role in the development of any carbon capture economy.

“We are proud to be able to support the development of this game-changing technology that has the potential to make a significant contribution to emissions reduction ambitions.”

Last November, ABS and HHI announced joint development projects for decarbonisation solutions. Korea Shipbuilding and Offshore Engineering was also a partner in this initiative.
