ClassNK has unveiled the “Guidelines for 3D Model-Based Approval (3DMBA),” outlining essential principles and practices for utilizing 3D models in design approvals. This innovative approach positions 3D models as the primary basis for approval, enhancing efficiency in the design process. Alongside these guidelines, ClassNK has launched its 3DMBA-compatible systems: the NK-PASS drawing approval management system and the ClassNK 3DViewer, which facilitate an integrated workflow for 3D model-based design approvals.
NK-PASS, traditionally used for 2D drawings, now supports OCX-based 3D models, streamlining approval processes. The ClassNK 3DViewer is designed to render these models, promoting digital data utilization within 3DMBA workflows. The guidelines aim to clarify the approval scope for design changes and foster a common understanding among shipyards, designers, shipowners, and classification societies.
As 3D models gain traction in ship design, they enhance visualization and communication of complex structures. ClassNK emphasizes the need for stakeholders to establish a shared understanding of approval processes, including submission units and design change management. Collaborating with ten Japanese companies, ClassNK conducted pilot tests to refine these processes, ensuring practical applicability in real-world scenarios. The guidelines also detail the treatment of 3D models as approval deliverables and their relationship with supplementary 2D drawings.
