United States

In the United States Merchant Marine, in order to be occupied as a QMED a person has to have a Merchant Mariner Credential issued by the United States Coast Guard with a QMED certification. Because of international conventions and agreements, all QMEDs who sail internationally are similarly documented by their respective countries.

  1. Fireman/Watertender
  2. Oiler
  3. Deck Engineer
  4. Junior Engineer
  5. Refrigeration Engineer
  6. Electrician
  7. Pumpman
