Mitsubishi Shipbuilding, NYK Line score ClassNK AIP for Large LCO2 Carrier
Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI) Group, and Nippon Yusen Kabushiki Kaisha (NYK Line) wee granted Approval in Principle (AiP) from ClassNK for joint development of CO2 transport technology for liquefied CO2 (LCO2) carriers.
LCO2 carriers transport liquefied CO2 at low temperature and high pressure, which is contained in the cargo tank system. Since the design of cargo containment system depend on the condition of liquefied CO2 such as their temperature and pressure, it is an important technical development issue to increase the size of cargo tank systems and hulls for future mass transportation.
In the joint development of LCO2 carrier, the feasibility and compliance with regulations and standards were confirmed for each cargo tank system and hull section, taking into account different tank pressure settings for medium and large vessels, which led to the successful grant of the AiP.
NYK is working together with the MHI Group, which possesses a wide range of technologies in the CCUS value chain, to achieve the early realization of not only small and medium-sized vessels but also large LCO2 carriers. Based on the design of the LCO2 carrier granted the AiP, NYK Line will further promote its participation in the CCUS value chain, such as by studying the design of the LCO2 carrier for each project, including further enlargement of the size of vessels.
