The American Bureau of Shipping (ABS) has published industry requirements for liquefied carbon dioxide (LCO2) carriers for safe and efficient transportation as more industries adopt carbon capture technologies.
Requirements for liquefied carbon dioxide carriers is believed to be the first publication available in the maritime industry dedicated to the design, construction, and classification of LCO2 carriers where liquefied CO2 is carried as cargo.
Patrick Ryan, Senior Vice-President and Chief Technology Officer at ABS, said that the new requirements provide much needed guidance to minimise risks to the crew, the vessel, and the environment.
He continued, “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.”
Why was the report published now? Well, as the ABS explains, as more industries adopt carbon capture, utilisation, and storage (CCUS) technologies as part of a decarbonisation strategy, the amount of captured CO2 will be greater than today’s consumption.
The excess CO2 needs to be transported both globally and/or locally for sequestration or various uses. Transporting captured CO2 over long distances will cause an increased demand for building dedicated liquefied CO2 (LCO2) carriers.
As a starting point, the report highlights the need for vessels to comply with both the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) and specific ABS requirements for carrying LCO2 in Type C independent tanks.
Diving beyond this, it also addresses ship survival capabilities, cargo tank location, ship arrangements, and cargo containment. It also outlines requirements for process pressure vessels, piping systems, material construction, quality control, and cargo pressure and temperature control systems.
And when it comes to those operating the ship, the report also covers personnel protection methods when it comes to filling limits for cargo tanks.
The release of the report follows the International Maritime Organisation (IMO) setting a goal on greenhouse gas emissions from ships to reduce the CO2 emissions per transport work, at an average across international shipping by at least 40% by 2030 when compared to 2008.
When compared to 2008, the total annual greenhouse gas emissions from international shipping are expected to decrease by at least 20%, aiming for 30% by 2030, and at least 70%, aiming for 80% by 2040.
