The IMCA international code of practice for offshore diving recognises a list of initial diver training certificates for those working offshore world-wide. The current list is available in Diver and diving supervisor certification
The following documents set out the criteria used for identifying appropriate certification and training:
- IMCA D 26/01 – Competence assessment of experienced surface supplied divers
- IMCA D 07/17 – Diver training certificates - IMCA acceptance criteria
- IMCA D 08/17 – IMCA minimum criteria for surface supplied diver training
In regulated waters, more restrictive lists of accepted certificates may apply.
