Deltamarin, DNV and AVEVA are very pleased to announce a strengthened collaboration following today’s approval by DNV for a 3D model used as part of the classification material prepared for Höegh Autoliners’ Aurora-class PCTCs.

The three companies have been cooperating to streamline approval processes for classification materials from drawings to 3D models using the new Open Class 3D Exchange (OCX) standard. Deltamarin, DNV and AVEVA continue to combine their expertise to take the next big step towards the future of design processes.

Deltamarin completed part of the steel design work for Höegh Autoliner’s Aurora-class PCTCs using AVEVA’s new E3D software and in close collaboration with AVEVA’s qualified marine team. E3D is the next generation design software that has OCX export capability along with other innovative features.

OCX is a new standard for class approval based on 3D models with the purpose of breaking down the barriers between different design platforms and software to enable the seamless exchange of idealized geometry and metadata between them. The 3D OCX model can replace traditional 2D structural drawings, thus saving time for Deltamarin and allowing DNV to respond more quickly to the designer’s needs. The OCX standard is the result of the joint industrial project ‘Approved (2016-2020)’ led by DNV. The standard is now jointly owned and managed by the OCX Consortium established in 2021 ( This consortium has brought together more than 30 industry leaders to jointly promote and maintain the standard. Membership consists of all major classification societies, major CAD vendors and various designers and yards.

Janne Uotila, CEO of Deltamarin, says: “Increasing productivity and shortening the calendar time for design through digitization is one of the internal development areas we have focused on at Deltamarin. This is a great practical example of this”.

Geir Dugstad, DNV’s Director of Ship Classification and Technical Director, continues: “The move away from 2D structural drawings to a 3D digital twin is a milestone for the maritime industry. This opens up new possibilities in data management of ‘assets, which I strongly believe will drive the safety and reliability of ship design and operation. A good example would be a more efficient process for verifying compliance with regulations. The OCX format helps designers control and optimize their designs and allows DNV to confirm compliance with the rules directly on the 3D design model.”

Hervé Lours, Vice President Maritime at AVEVA adds: “AVEVA’s mission has been to increase productivity in ship design, manufacturing and operations for decades; It was then a no-brainer to provide Deltamarin, DNV and the OCX Consortium with our expertise in breaking down silos and facilitating data exchange between software and players; this success highlights the additional value of the digital twin and paves the way for even greater adoption in the maritime industry.”
