Japanese companies Mitsubishi Shipbuilding and NYK Line have been granted approval in principle (AiP) from the Japanese classification society ClassNK for the joint development of liquefied CO(LCO2) carriers, the companies said in a joint statement on May 16.

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 depends on the temperature and pressure of LCO2, it is an important technical development issue to increase the size of cargo tank systems and hulls for future mass transportation, the companies said.

“In the joint development of LCO2 carriers by Mitsubishi Shipbuilding and NYK Line, which is so performed as to resolve such technical issues, 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, leading to the grant of the AiP,” they said.

NYK Line said that CO2 transport technology by large vessels will greatly contribute to the realisation of a carbon-neutral society.
