ClassNK has issued an approval in principle (AiP) for a large liquefied CO2 carrier (50,000m3) jointly developed by Dalian Shipbuilding Offshore Co., Ltd. (DSOC) and Nantong Offshore Design & Research Institute Co. Ltd (NODRI). The certification confirms the feasibility of the vessel from regulatory and safety perspectives.

ClassNK reviewed the design concept of the vessel based on its ‘Rules and Guidance for the Survey and Construction of Steel Ships’, including Part N, which incorporates the IGC Code, an international code for the construction and equipment of ships carrying liquefied gases such as LCO2 and LNG in bulk. Upon confirming compliance with the prescribed requirements, ClassNK issued an AiP.

AiP Handover Ceremony

Approval in Principle (AiP):

At the initial stage of designing or before the specific target ship to be implemented is decided, the design is examined based on the existing regulations such as international conventions and ship classification rules, and an Approval in Principle (AiP) is issued as proof of conformity with requirements. It also prevents rework of regulatory aspects in the post-process, shortens the examination time at the time of class registration, and can be used as a technical basis for external appeal of the design status.
