Diving Contractor Membership

Application Process for Contractor Membership of the IMCA Diving Division

Any applicant company which conducts offshore diving operations will be required to become a member of the IMCA Diving Division before applying for membership of any other technical division.

Applicants should note the following points:

  • There are two basic types of IMCA Diving Division contractor members:
    • those undertaking surface supplied diving operations only
    • those utilising both surface supplied and saturation diving techniques.
  • Full contractor membership of the IMCA Diving Division is only open to offshore diving contractors.
  • Temporary contractor membership of the IMCA Diving Division may be open to applicant companies that fulfil IMCA’s acceptance criteria in all respects other than the provision of evidence of conducting an offshore diving project.
  • Temporary members can upgrade from temporary to full diving contractor membership of the IMCA Diving Division if they meet the necessary IMCA acceptance criteria.
  • Companies can apply to extend existing Diving Contractor Membership of the IMCA Diving Division to an affiliate in another region.

All submissions that are received are handled on a first come first served basis.  At this time, we are unable to give an accurate timeline on how long an assessment procedure might take.


Prior to the consideration of any application for Diving Contractor membership, IMCA will invoice the applicant diving contractor for the applicable audit fees.

IMCA will not begin the audit stage of the assessment procedure until the required fee has been received.  It should be noted that receipt of payment for the desktop audit does not guarantee acceptance into IMCA Diving Contractor membership.  Any unsuccessful applicants that choose to re-submit will also be invoiced as per the below rates.  All applications are subject to the desktop and on-site audits.
