ClassNK, a reputable organization in ship design assessment and approval, has recently issued an Initial Approval (AiP) for the design of 42,000 cubic meters of liquid carbon dioxide (LCO₂) carriers. This approval is aimed at addressing the growing market needs for CO₂ carriers that transport this gas from capture sites to storage locations.
Importance of Initial Approval (AiP) in Ship Design
The Initial Approval (AiP) is a key stage in the design of new ships, reviewing designs based on existing regulations, including international conventions and ship classification rules. This approval serves as evidence of compliance with legal requirements and prevents the need for subsequent changes in post-design stages. Thus, it reduces review time during class registration and can serve as a technical basis for external requests regarding design status.

Development of New Technologies and Social Implementation
ClassNK has addressed risk assessment through HAZID by conducting design reviews based on Section N of the "Rules and Guidelines for the Inspection and Construction of Steel Ships," which includes the IGC Code. The IGC Code is an international code that sets safety requirements for the construction and equipment of ships that carry liquid gases such as LCO₂ and LNG in bulk. After confirming that the specified requirements have been met, ClassNK proceeded to issue the AiP.
This approval not only helps standardize ship hull designs but also facilitates the development of carbon capture and storage (CCS) projects globally. Given the global trends in reducing carbon emissions and climate change, the demand for CO₂ carriers is increasing. This need clearly demonstrates the importance of new technologies in the maritime and energy transportation industries.
ClassNK will continue its efforts to assist in the development of new technologies and social implementation through safety assessments and continuous improvement in this field. This initiative, as an important step towards environmental protection and sustainable development, can lead to reduced dependence on fossil fuels and improved environmental conditions.
