Becoming a commercial diver in Europe follows a clear route: pass a diving medical, complete recognised training in stages (from scuba up to surface-supplied diving), register under a recognised national scheme, and then build experience and add specialist tickets. In the Netherlands that scheme is run by NDC-RI with examinations by Hobéon-SKO — a route that is recognised for offshore work through IMCA and accepted in the United Kingdom via the HSE approved list.
Step 1 — Meet the entry requirements
Start with a diving medical that confirms you are fit to dive, carried out by a qualified diving physician. You will also need to meet minimum age and basic fitness/swimming requirements, and for some routes a basic scuba level to begin with.
Step 2 — Train in stages (scope levels)
Dutch commercial diving is built up in scope levels, from scuba at the entry end up to surface-supplied diving (SSE / B50). Training is blended — online theory combined with hands-on practice at a diving facility (for example a deep training basin, conditioned dive towers and a decompression chamber). Each level unlocks deeper or more complex work.
Step 3 — Get registered
Pass the Hobéon-SKO examinations for your level and register with NDC-RI. That registration — not the course certificate on its own — is your qualifying credential for professional diving work in the Netherlands.
Step 4 — Add recognition and tickets for where you want to work
Match your credentials to your target market. The Dutch scheme is recognised for offshore work through IMCA; the B50 qualification is on the UK HSE approved list (reviewed periodically); and there is a recognised crossover route towards ADAS in Australia. For specific jobs you then add an offshore medical, offshore survival (BOSIET/HUET), a Diver Medic Technician certificate, and welding qualifications where relevant.
Step 5 — Build experience
Most divers start inshore — civil, harbour and construction work — to log hours and prove reliability, then move offshore as they gain experience, progressing from air diving towards saturation work over time. Experience and a clean safety record are what open the better-paid roles.
Why train in Europe
Training in Europe means working within the recognised EN ISO / DNV framework, avoiding the large tuition debt associated with US schools, and — within the EU/EEA — training and working without a separate work visa. Courses can be followed in English, with English materials for international participants.
Frequently asked
How long does it take to become a commercial diver?
It depends on the scope level. The core surface-supplied route is a matter of weeks of blended training per level plus examinations — but building the experience needed to work offshore takes considerably longer.
Do I need to speak Dutch to train in the Netherlands?
No. Courses can be followed in English, with English course materials for international participants.
Can I work across Europe with a Dutch qualification?
The Dutch scheme is recognised for offshore work (IMCA) and in the UK (HSE list). Individual countries and employers set their own additional requirements, so always check what a specific job needs.
What is the difference between inshore and offshore diving?
Inshore (civil/harbour) work is the usual starting point. Offshore work — oil, gas and offshore wind — pays more and requires extra tickets and experience.
