The international classification society ClassNK has announced new guidelines introducing a shift toward a 3D model–based approach in the ship design approval process.
According to sea-news.az, citing Seanews.az, the document outlines in detail the principles of using 3D models as the primary reference in project evaluation and approval, along with standardized technical procedures for implementation.
To support this transition, ClassNK has also launched the “NK-PASS” drawing approval management platform and the “ClassNK 3Dviewer” software. These digital solutions enable the presentation, analysis, and verification of OCX-format 3D models entirely in an electronic environment.
The guidelines further address key aspects such as change management in ship design projects, the structure of submitted technical data, the relationship between 3D models and traditional 2D drawings, and their parallel use during the transition period.
ClassNK tested the effectiveness of this approach through a pilot project involving 10 Japanese companies, with the results incorporated into the new guidelines.
According to the organization, the 3D-based approval system is expected to establish more unified standards across shipyards, designers, shipowners, and classification societies, while also significantly improving the speed and transparency of the design approval process.
