Diver Medical Technician Job: Duties, Training, and Career Path

 A Diver Medical Technician (DMT) plays one of the most critical roles in the commercial diving and offshore industries. When a diver is working underwater—whether on an oil platform, a salvage mission, or a scientific expedition—there must be a trained medical professional on site who understands both diving medicine and emergency response in remote locations. That person is the DMT.

If you’re considering a career in diving or emergency medicine and want a job with adventure, responsibility, and excellent earning potential, becoming a Diver Medical Technician may be a perfect fit.

What Is a Diver Medical Technician?

A Diver Medical Technician is a trained emergency medical provider who specializes in treating medical problems that occur in diving environments, including:

  • Decompression sickness

  • Barotrauma

  • Hypothermia

  • Hyperbaric chamber emergencies

  • Trauma from underwater tools or equipment

DMTs are certified to perform advanced first-aid procedures offshore, in remote marine locations, or on vessels where immediate hospital care isn’t available.

They work alongside commercial divers, dive supervisors, hyperbaric chamber operators, and offshore safety teams.

Where Do Diver Medical Technicians Work?

DMTs work in environments where diving operations are routine. Common workplaces include:

 Offshore oil and gas platforms

Supporting commercial divers performing inspections, repairs, and construction.

 Saturation diving operations

Standing by during long-duration diving missions that require specialized emergency preparedness.

 Hyperbaric facilities

Operating hyperbaric chambers for treatment or training.

 Marine construction and salvage

Providing medical care during underwater bridge repairs, ship salvaging, or coastal engineering projects.

Scientific and research expeditions

Assisting diving teams studying marine life or conducting underwater surveys.

Diver Medical Technician Job Duties

DMT responsibilities vary based on the diving environment, but common duties include:

Emergency Medical Care

  • Assessing and stabilizing injured or ill divers

  • Managing decompression sickness (the bends)

  • Administering oxygen therapy and IV fluids

  • Treating lacerations, fractures, and equipment-related injuries

  • Using AEDs and performing CPR

Hyperbaric Operations

  • Operating and monitoring hyperbaric chambers

  • Conducting therapeutic recompression

  • Keeping accurate medical and chamber logs

Safety and Prevention

  • Inspecting dive teams for fitness to dive

  • Monitoring environmental conditions

  • Ensuring compliance with safety protocols

  • Maintaining medical equipment and supplies

Documentation and Reporting

  • Writing detailed medical incident reports

  • Communicating with shore-based physicians

  • Keeping daily medical logs for diving operations

Skills Needed to Be a Diver Medical Technician

Successful DMTs often share these skills:

  • Strong emergency medical training

  • Ability to remain calm under pressure

  • Excellent communication in high-risk settings

  • Strong physical fitness

  • Understanding of diving physics and physiology

  • Knowledge of dive tables and decompression models

  • Ability to work in remote, sometimes harsh environments

Many DMTs also have commercial diving backgrounds, though this is not always required.

How to Become a Diver Medical Technician

1. Meet the Prerequisites

Most training programs require:

  • Current CPR/First Aid/AED certification

  • EMT-Basic or equivalent emergency medicine training

  • Good physical health

Many candidates are already EMTs, paramedics, nurses, or commercial divers.

2. Complete a DMT Training Course

A typical Diver Medical Technician course includes:

  • Advanced life support

  • Diving physiology

  • Neurological assessment

  • Hyperbaric chamber operation

  • Management of diving emergencies

  • Offshore medical protocols

Programs are usually 2–4 weeks long and include classroom instruction plus hands-on hyperbaric training.

3. Earn Certification

Many regions follow standards from organizations such as:

  • IMCA (International Marine Contractors Association)

  • EDTC (European Diving Technology Committee)

  • UHMS (Undersea & Hyperbaric Medical Society)

Certification must be renewed every 2–3 years.

4. Gain Experience Offshore

Many new DMTs start as:

  • Offshore medics

  • Dive tenders

  • EMTs on marine vessels

  • Hyperbaric chamber operators

  • Salary and Job Outlook

    Diver Medical Technicians generally earn high pay due to the specialized skills and remote work locations.

    Typical earnings:

    • $350–$600 per day offshore

    • $70,000–$120,000 per year, depending on experience

    • Higher wages during saturation diving operations

    Demand is steady, especially in the offshore energy sector, marine construction, and hyperbaric medicine.

  • Pros and Cons of the DMT Career

     Pros

    • High earning potential

    • Unique and adventurous work environment

    • Opportunity to save lives

    • Short training time compared to many healthcare careers

    • Highly respected role on dive teams

     Cons

    • Long stretches away from home

    • Physically and mentally demanding

    • High-risk environment

    • Irregular schedule depending on offshore contracts

    • Is the Diver Medical Technician Job Right for You?

      This career is ideal for someone who:

      • Enjoys emergency medicine

      • Wants to work in unique marine environments

      • Can stay calm under pressure

      • Doesn’t mind extended time offshore

      • Likes hands-on, technical medical work

      For anyone who loves both the medical field and the ocean, becoming a Diver Medical Technician is one of the most rewarding and exciting career paths available.
