Classification society Korean Register (KR) on Monday (11 July) said it has granted an Approval in Principle (AiP) to Hyundai Heavy Industries (HHI) AiP for the design of its LNG-fuelled 40K CBM LCO2 carriers.
Under a joint development project, HHI carried out the basic and structural design of the LCO2 carrier, while KR verified the safety and conformity of the design, reviewing the class rules and international conventions.
“One of the main aims of the project was to explore the economic feasibility of large pressure-type CO2 storage tanks,” said KR.
“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 design which has been awarded the 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 will be 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 commercialisation 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 decarbonisation.”
