Mitsui O.S.K. Lines (MOL) has received an approval in principle (AiP) from ClassNK for a liquefied CO2 (LCO2) carrier design featuring wind-assisted propulsion systems. Developed in collaboration with Samsung Heavy Industries, the vessel is designed to transport approximately 40,000 cubic meters of liquefied CO2 using three Wind Challenger units, a rigid sail system that harnesses wind power for propulsion.
The design enhances visibility by positioning the navigation bridge and accommodation areas towards the bow, facilitating the installation of the sail systems. Safety features include a passage between the engine room and accommodations, as well as optimized locations for navigation equipment and lifeboats. The incorporation of wind power is anticipated to lower fuel consumption and greenhouse gas emissions during CO2 transport, contributing to carbon capture and storage efforts.
MOL conducted a hazard identification study with Samsung Heavy Industries and ClassNK to evaluate the design’s risks and confirm its technical feasibility and safety. The Wind Challenger system allows for automatic extension, retraction, and rotation, enabling efficient use of wind power while ensuring safe navigation. MOL aims to increase its fleet of vessels equipped with Wind Challenger systems to 25 by 2030 and 80 by 2035 as part of its emissions reduction strategy.
