NYK gets approval for 3D basic design drawings of multipurpose boxship




April 18 ------ Classification society ClassNK has granted approval to the basic design drawings of a multipurpose containership developed by Japanese shipping company NYK using 3D models. 

  

Traditionally, the sharing of design information among shipyards, shipowners, and class societies has relied on 2D drawings, necessitating the conversion of shipyard-created 3D models into 2D drawings for approval processes. This practice, along with the input of drawing data into the class society’s ship structure design support system and the model modifications by designers, has posed challenges in terms of time and cost for both parties. Additionally, accurately interpreting complex 2D drawings requires extensive experience and expertise, resulting in the precision of information sharing among parties dependent on the individuals involved. 

  

Recognizing these challenges, NYK Line and ClassNK have been advancing a project to enhance the use of 3D models in new ship designs. The 3D model data created by NYK Line on its ship design 3D CAD system was processed with the interface system of ClassNK’s PrimeShip-HULL, which ensures the use of consistent design data across different tools. 

  

Meanwhile, ClassNK has completed all plan approvals at the basic design stage without the need for the conversion to 2D drawings. This milestone marks the world’s first ocean-going ship to complete the basic design process, including class approval, solely through 3D drawings from the conceptual design to the basic structural design, during the initial stages of ship construction (as researched by NYK Line and ClassNK as of March 28, 2024). Moving forward, ClassNK will continue to work on standardizing the 3D plan approval scheme and strive to support digitalization and advanced initiatives in ship design. 

  

Earlier on, ClassNK joined forces with NAPA, a provider of maritime software, services, and data analysis, to jointly support the use of 3D models in the ship design approval process.
