ABS, Daewoo Shipbuilding to develop LCO2 carrier

The American Bureau of Shipping (ABS) and South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) will jointly develop designs for a 70,000 m³ very large, liquefied CO₂ (LCO₂) carrier, ABS said on September 16.

The joint development project (JDP) is in response to the development of carbon capture utilisation and storage (CCUS) technology, which will ultimately require larger vessels for CO₂ transport than those used in the existing food industry, it said.

“CCUS can play a role in reducing emissions in a range of industries, but the supply chain will need vessels capable of transporting CO₂ safely and efficiently.  That’s why this JDP with DSME is so important, not just for the maritime industry but for ambitions to reduce the carbon footprint of the entire global economy,” said Patrick Ryan, ABS senior vice president, global engineering and technology.

DSME, which has previously developed a conceptual design of a 100,000 m³ LCO₂ carrier, is developing a new design that can increase operational efficiency by increasing tank size. In order to increase tank capacity, the JDP will study the application of various steel materials as well as existing low-temperature steel.

The new LCO₂ vessels will comply with the ABS Rules for Building and Classing Marine Vessels and the ABS Guide for Liquefied Gas Carriers with Independent Tanks as well as the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code).

“DSME will maintain its unique competitiveness for the technology and quality in the field of liquefied gas carriers, such as LNG and LPG carriers, through this development of very large LCO₂ carriers. And it will be able to maintain an advanced technology in the market of LCO₂ carriers, which is one of the major concerns in the CCUS sector,” said Nuno Kim, DSME director, head of ship basic design division.
