Yes. The Dutch commercial-diving qualification scheme is recognised by IMCA. The Netherlands’ national scheme — run by the NDC Registration Institute (NDC-RI) and examined by Hobéon-SKO — appears on IMCA’s list of national diver-certification schemes it accepts. The important nuance: IMCA recognises the scheme, not an individual school or diploma. What counts for an employer is that you hold a valid registration under that Dutch scheme.
What IMCA actually recognises
IMCA (the International Marine Contractors Association) is the body most offshore diving contractors work to. It does not issue most diver certificates itself. Instead, it publishes which national certification schemes it accepts for offshore diving work, and the Dutch scheme — covering surface-supplied and closed-bell diving — is on that list.
Recognition applies to how the scheme is governed: government oversight, audits, and certificates issued by a designated national body. It is not an endorsement of one particular training centre, and it is not a claim that your diploma is itself an “IMCA certificate”. You qualify through the Dutch scheme; IMCA recognises that scheme.
Diver and supervisor are not the same thing
Being a registered Dutch diver is not the same as being an IMCA-recognised diving supervisor outside Dutch waters. Supervisor recognition beyond the Netherlands runs through a separate IMCA route (assessment / mutual recognition), so you should not assume your Dutch dive-team-leader status transfers automatically to an offshore project abroad.
This distinction matters on real vacancies: offshore employers spell out exactly which supervisor credential they require, and it is often not the same document you hold for Dutch inland work.
What this means for working in the North Sea or the Gulf
For most offshore jobs your diver registration from a recognised scheme is the qualifying base. On top of it, employers typically ask for extra tickets: an offshore diving medical, offshore survival training (BOSIET/HUET), and — for many teams — a Diver Medic Technician on board. Welding roles add welder qualifications such as AWS D3.6M or EN ISO 15618-1.
In short: your Dutch qualification opens the door; the specific job advert tells you which additional certificates you need to stack on top.
How to qualify under the Dutch scheme
You train at a recognised Dutch centre through a series of scope levels — from scuba up to surface-supplied diving (SSE / B50) — pass the Hobéon-SKO examinations, and register with NDC-RI. That registration is your qualifying credential.
Recognition lists and information notes change over time. Before relying on any certificate for a specific job, check IMCA’s current information notes and the NDC-RI register for the latest status.
Frequently asked
Does IMCA issue my diving certificate?
No. Your certificate comes through the Dutch NDC-RI scheme, examined by Hobéon-SKO. IMCA recognises that national scheme for offshore work — it does not issue the certificate itself.
Is a Dutch dive supervisor automatically an IMCA supervisor abroad?
No. Supervisor recognition outside Dutch waters is a separate step through IMCA’s assessment / mutual-recognition route. Check IMCA’s competence guidance for the country and role you are targeting.
Is my Dutch B50 certificate valid in the United Kingdom?
The Dutch B50 qualification appears on the UK HSE list of approved diving qualifications, which lets you work under UK HSE diving rules. That list is reviewed periodically, so always confirm the current HSE list before you rely on it.
Which employers accept a Dutch diving qualification?
Contractors that work to IMCA guidelines across the North Sea and the Gulf. Each vacancy states the exact certificates and additional tickets it requires — treat the advert as the source of truth.
