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:

1. DNV
2. BV
3. LR
4. Turk Lloydu
5. Korean Register
6. NAPA
7. AVEVA
8. Hexagon
9. Chantiers de l'Atlantique
10. NDAR
11. Kongsberg Maritime
12. CADMATIC
13. AITAC
14. PROSTEP

Two new vendors joined the OCX-IF from January 1, 2024:

1. Dassault Systèmes
2. SSI - Ship Constructor

The OCX-IF is operative from August 2023.
