ClassNK completes 3D CAD model project

This project examined the technical development required in each process of plan approval by JMU, NAPA, and ClassNK to realize 3D model based plan approval. In the feasibility study, ClassNK conducted a trial evaluation for hull structural design on a 3D CAD model of 300,000dwt ore carrier designed and created by JMU, using ‘NAPA Designer’, a 3D CAD software application for ship design developed by NAPA, as a 3D model viewer. Plan submission, storage, and notification of examination results were made using the society’s electronic plan examination system ‘NK-PASS’.

The investigation concluded that information required for class approval can be confirmed through a 3D CAD model, and that NK-PASS is also compatible with 3D CAD models. The results of this survey will serve as a basis for future technical studies, and the dociety will continue to work with the industry to realize 3D model based plan approval.

Hayato Suga, corporate officer and director of plan approval and technical solution division, said, “This study has proven the future potential of 3D model based approvals. 3D based design can be the key to improving digital solutions in the ship industry, including the ship design process, approval process and later fleet maintenance.”
