The Consortium members decided in September 2021 to establish an OCX Interoperability Forum (OCX-IF) to ensure the seamless exchange of OCX models between SW systems. A Task Group (TG)  coordinated by DNV and with participation from BV,  Chantiers de l’Atlantique, PROSTEP, SSI/NDAR, and NAPA was established to prepare a proposal for how to set up and run the OCX-IF. The TG delivered their proposal to the OCX Consortium members in June 2022. The OCX Consortium members decided to establish the OCX-IF at the full member meeting on November 10, 2022.

The TG was engaged to work out an Agreement governing the operation of the OCX-IF.  The final agreement was signed in August 2023 between the following OCX Members:

• DNV
• BV
• LR
• Turk Lloydu
• Korean Register
• NAPA
• AVEVA
• Hexagon
• CADMATIC
• AITAC
• PROSTEP

The OCX-IF is operative from this date.
