International recognition of your Dutch diving qualification
Divers train in the Netherlands to work worldwide. This page explains — precisely and honestly — how the Dutch professional diving scheme relates to the international frameworks employers ask for: IMCA, HSE (UK), ADAS (Australia) and more.
How the Dutch scheme works
Dutch professional diving qualifications are not issued by a school but by the national scheme: training at a recognised institute (such as BC-opleidingen), an independent national exam, and registration with NDC-RI, the Dutch register for occupational diving, with Hobéon as the independent examination body. That separation — school, exam and register are independent of each other — is exactly what international frameworks look for.
IMCA
IMCA’s certification guidance lists the Dutch scheme among the national diver-training schemes it recognises (surface-supplied and closed bell categories, IMCA D 01/18 and successors). Note: IMCA recognises the national scheme — an individual diver needs a valid NDC-RI registration, and dive-supervisor recognition outside Dutch waters runs through IMCA’s own mutual-recognition route.
HSE (United Kingdom)
HSE’s list of approved diving qualifications names “NDC Registratie Instelling B50” under Schedule 1 (offshore diving) and “NDC Registratie Instelling B30” under Schedule 2 (inland/inshore diving), both without a listed expiry date; the earlier “Duikarbeid Categorie” entries remain listed until 1 February 2027. In short: a Dutch B50 or B30 diver can work under UK regulations. See our dedicated page for UK and Irish divers for the full breakdown.
ADAS (Australia)
ADAS operates crossover arrangements for Dutch (NDCCI/Hobéon) certificates towards the corresponding Australian levels — a route towards work in Australia and ADAS-aligned markets.
IMCA Diver Medic Technician
BC-opleidingen is listed in IMCA’s register of approved Diver Medic training providers — the only provider in the Netherlands and the Benelux.
DNV (welding)
Underwater welder qualification at our Hyperbaric Welding Center is examined under the DNV flag (personnel certification, ISO/IEC 17024), to EN ISO 15618-1 with preparation for AWS D3.6M.
The honest print
- Recognition frameworks change. We verify our claims against the source documents; always check the current requirements of your target market and employer before you plan a career step.
- IMCA recognition concerns the national scheme and the diver’s valid registration — no school anywhere can hand out “an IMCA certificate” directly.
- A Dutch dive-supervisor qualification is recognised for Dutch waters; working as an IMCA supervisor abroad requires IMCA’s separate route.
- Tell us where you want to work: we will tell you exactly what that market requires — including what your Dutch qualification does not automatically cover.
