Korean Register (KR) and Hyundai Heavy Industries (HHI) conducted a joint development project (JDP) to develop 40K CBM LCO2 carriers fueled with LNG.
Under the JDP, HHI carried out the basic and structural design of the 40K CBM LCO2 carrier, while KR verified the safety and conformity of the design reviewing the class rules and international conventions. The resulting concept design has now been awarded Approval in Principle (AIP) by KR.

One of the main aims of the project was to explore the economic feasibility of large pressure-type CO2 storage tanks. To increase the size of the CO2 storage tanks, special materials with low-temperature and high-tensile need to be used instead of ordinary steel, which makes it challenging to control the thickness and weight of the tanks.
The LCO2 carrier designed which has been awarded AIP, is capable of storing up to 40K CBM using a type C pressure tank made of existing low-temperature and high-tensile materials. An LNG fuel propulsion system has been installed, ensuring low-carbon emissions during the carrier’s operation.
The safety of the carrier’s cargo hold, cargo tank and supporting structure has been verified and approved using KR’s SeaTrust-HullScan software solution which was developed in house.
A KR official said:
This AIP is a significant achievement, bringing the commercialization of large LCO2 carrier technology even closer. KR will continue to support the industry’s work to develop CO2 capture, storage and burial-related technologies, while proactively working to address the industry-wide challenge of decarbonization
