On March 28, NYK received approval from ClassNK for the 3D model-based approval of the basic design of a new multi-purpose container vessel.
This marks the first instance of an oceangoing ship completing the entire basic design process, including classification approval, using only 3D drawings, as confirmed by NYK and ClassNK. Traditionally, the structural design of new ships is communicated through 2D drawings, which are shared among shipowners, shipyards, shipping companies, and classification societies.
Even when 3D drawings are created during the basic design, they are usually converted to 2D format for classification society approval due to differences in 3D CAD systems among companies and ship types. This conversion process and the subsequent 3D model evaluation based on 2D drawing data have often required significant expertise and experience to interpret accurately.
In response to these challenges, NYK and ClassNK collaborated to streamline the approval process for the new ship’s design. They developed a collaboration system allowing ClassNK to directly check the 3D model data created by NYK, eliminating the need for data conversion to 2D drawings.
This approach not only improves efficiency but also facilitates more intuitive understanding and smoother communication among all parties involved in the design process.
