The IMCA Diver Medic Technician (DMT) is an internationally recognised qualification that trains a non-diving or diving team member to give advanced first aid to an injured diver and to assist a doctor remotely — inside or outside a decompression chamber — until professional medical help arrives. It exists because offshore dive sites are often hours from the nearest hospital, and IMCA’s code of practice for offshore diving expects that capability to be on the team itself, not summoned from shore.
What the qualification actually covers
A Diver Medic Technician is trained to recognise and stabilise diving-related injuries and medical emergencies, provide advanced first aid, and communicate with a doctor at a distance to carry out their instructions safely — including, where trained and equipped, treatment inside a decompression chamber. The course combines theory (often delivered partly online) with hands-on practical training and concludes with a formal assessment.
IMCA — the International Marine Contractors Association — does not deliver the training itself. It approves the training providers that are allowed to run a recognised DMT course, under its own code of practice for the role (IMCA D020). Only providers on IMCA’s own register count as “IMCA-approved”.
Why offshore dive teams need one
IMCA’s guidelines for offshore diving operations call for diver-medic capability within a professional dive team: someone on the team, besides the supervisor, trained to provide advanced first aid and to support a doctor remotely if a diver is injured. That is why contractors running IMCA-guided projects — across the North Sea, the Gulf and most other offshore markets — routinely list a valid Diver Medic Technician certificate among their crewing requirements.
It is also why the certificate has a fixed validity rather than being a one-off qualification: dive teams need to demonstrate the capability is current, not just that someone once passed a course.
Where to actually train in Europe
Most of Europe’s IMCA-approved Diver Medic Technician providers are based in the United Kingdom. On the European mainland, the picture is much thinner: according to IMCA’s own directory of approved training providers, BC-opleidingen in the Netherlands is the only IMCA-approved DMT provider in the Netherlands and the Benelux, and one of only three providers on the entire European mainland.
That gap matters in practice for divers based in France, Germany, Scandinavia and elsewhere on the continent, who otherwise face a trip to the UK (or further) to qualify or refresh. BC-opleidingen’s course runs in Enkhuizen, about one hour from Amsterdam Schiphol, taught in English.
Admission: what you need before you book
Admission to the IMCA D020 course requires a recognised offshore diving qualification and a valid diving medical — that is IMCA’s own entry requirement for the role, not a provider add-on. Candidates who qualified outside the country where they train can usually have their certificate assessed for equivalence by the relevant national registration body before booking.
Validity and the refresher window
The Diver Medic Technician certificate is valid for two years. A shorter refresher course keeps it current; IMCA’s renewal window typically opens some weeks before the certificate’s expiry date and closes a limited period after it — outside that window, the full initial course has to be repeated rather than the shorter refresher, so it pays to plan ahead rather than let the date slip.
Frequently asked
Is there an IMCA-approved Diver Medic Technician course in Germany or France?
Not currently. According to IMCA’s own directory, the European mainland has only three approved DMT providers, and neither Germany nor France is among them. Divers based there typically train in the Netherlands or the UK.
How is the IMCA DMT different from a recreational “diver medic” course?
Recreational diver-medic courses, aimed at sport divers, are not IMCA-approved and are generally not accepted by offshore employers running IMCA-guided operations. If the goal is to meet an offshore crewing requirement, the certificate needs to come from a provider on IMCA’s own approved-provider register.
How long is the Diver Medic Technician certificate valid?
Two years. A shorter refresher course renews it within IMCA’s renewal window; outside that window, the full initial course has to be repeated.
Do I need to already be an offshore diver to take the course?
Yes. IMCA D020 requires a recognised offshore diving qualification and a valid diving medical to be admitted to the course. If you qualified outside the country where you train, your certificate is typically assessed for equivalence by the relevant national registration body before you book.
What does the course cost?
Pricing and current start dates vary by provider and change over time — check the course page of your chosen provider for up-to-date fees rather than relying on a figure quoted elsewhere.
Who approves Diver Medic Technician training providers?
IMCA (the International Marine Contractors Association) maintains its own register of approved providers under its code of practice for the role. IMCA does not deliver the training itself — only providers listed in that register can issue an IMCA-recognised certificate.
