NYK has launched a crew transfer vessel (CTV) newbuilding project, integrating 3D technology throughout its design and construction phases. Collaborating with Kosaba Shipbuilding Co., Ltd. and Smert Design Co., Ltd., the initiative aims to enhance safety, operability, and maintenance efficiency for CTVs transporting crews to offshore wind farms.
Traditional 2D design methods have often led to challenges in communication and adjustments during construction. To mitigate these issues, NYK has adopted a comprehensive 3D modeling approach. This allows for a thorough examination of the hull structure and equipment arrangement, enabling early identification of potential interferences and improving layout accuracy. The 3D model also facilitates design front-loading, minimizing rework during construction.
During the construction phase, the vessel was built according to the 3D model, with 3D scanning employed to monitor deviations from the original design. This method helped detect thermal deformation and assembly tolerances specific to aluminum catamarans, ensuring quality enhancement. Additionally, the project produced 3D digital drawings that consolidate specifications and construction data linked to the model, streamlining vessel management and maintenance operations post-delivery.
The CTV specifications include an overall length of approximately 28 meters, a breadth of about 9 meters, and a gross tonnage of around 145 tons, with construction taking place at Kosaba Shipbuilding Co., Ltd. in Kamaishi City, Iwate Prefecture.
