NAPA and Bureau Veritas partner on class approval of 3D hull designs

Maritime software provider NAPA and class society Bureau Veritas (BV) have announced a partnership to promote the use of 3D models in the class approval process for vessel designs, in place of 2D drawings.

While naval architects already often use 3D models to design ships, the assessment of these designs by class typically requires that they are translated into 2D and then back again into 3D, a time consuming and potentially error-laden process.

NAPA and BV aim to improve on this by creating a new process that will allow BV to perform its rule checks without needing to re-create 3D models from 2D drawings, based on the neutral OCX (Open Class eXchange) format.

Once the designer shares the hull data based on the OCX format from its design software, BV can import it into NAPA Steel to automatically generate the calculation models used in BV’s rule-checking software. 

In addition, BV will provide access to its web-based collaborative platform (VeriSTAR Project Management) to share comments and the progress of the design review with shipyards, designers and shipowners in real-time.

“This innovative breakthrough means that we have a viable and effective solution to use 3D model-based approval,” said Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas Marine & Offshore.

“The shift to 3D approval is important as it underpins what will be the next generation of vessel designs. It also means we will be able to collaborate more closely and more efficiently with designers to better iterate vessel designs to meet the safety and sustainability challenges of the future.”
