Development of Hanwha Ocean Liquefied CO2 Carrier

Abstract The interest in carbon neutrality is growing around the world as human faces the climate crisis caused mainly by greenhouse gas emission. The methodologies for carbon reduction are being introduced in every industry and carbon reduction through Carbon Capture Utilization & Storage (hereafter “CCUS”) is being recognized as one of the most feasible carbon reduction plan at the moment. CCUS is defined as a system of technologies that intergrates three stages: CO2 capture, transportation and utilization & geological storage. The transportation sector is a major part in CCUS value chain to link the capture sector and utilization & storage sector. Transportation methods of trucks, trains, pipelines, ships, etc. are being considered in the CCUS value chain and pipelines and ships are applicable in ocean transportation field. As the transportation distance of CCUS projects under development becomes longer and the total transportation volume is increased, ocean transportation using a dedicated liquefied CO2 (LCO2) carrier is expected to play a key role in carbon transportation of CCUS chain. In these market trends, Hanwha Ocean began developing a new vessel that can transfer liquid CO2 safely. This paper is to introduce the design development of Hanwha Ocean LCO2 carrier such as ship & cargo tank design, tank material, CHS (Cargo Handling System) test facility, etc.
