New standard for 3D model-based design to streamline approval processes

Finnish ship design firm, Deltamarin, has received 3D model-based approval from DNV for classification material relating to Höegh Autoliners’ Aurora-class pure car truck carriers.
Deltamarin and DNV have been collaborating with industrial software specialist Aveva on the development of its 3D model-based design software, E3D, which is described as next-generation software with a range of innovative features including the new ‘Open Class 3D Exchange’ (OCX) standard.
OCX is a system that breaks down barriers between different design and software platforms to enable the exchange of idealised geometry and metadata between them, the companies said.
The OCX 3D model can replace traditional 2D structure drawings, thereby saving time for Deltamarin and enabling DNV to respond more quickly to designers’ needs.
Deltamarin CEO, Janne Uotila, commented: “Increasing productivity and shortening the calendar time for design through digitalisation is one of the internal development areas we have been focusing on at Deltamarin. This is a great practical example of that.”
Speaking for the classification society, DNV’s Geir Dugstad, director of Ship Classification & Technical Director, said: “Moving away from 2D structure drawings to a 3D digital twin is a milestone for the maritime industry ... The OCX format helps designers to control and optimise their designs and enables DNV to confirm rule compliance directly on the 3D design model.”
Aveva’s Marine vice president, Hervé Lours, said that since his company’s mission had been about increasing productivity in ship design, manufacturing and operation for decades, the project with Deltamarin and DNV had focused on easing data exchange between parties. “This success highlights an additional value of the digital twin and paves the way for an even larger adoption in the maritime industry,” he said.
The OCX standard is owned and managed by the OCX consortium, a consortium comprising all major classification societies, significant CAD vendors, and several design firms and shipyards.
