What is the primary function of a QMED on a vessel?

The primary function of a QMED, or Qualified Member of the Engine Department, is to assist in maintaining the machinery and engineering systems aboard a vessel. This role is crucial for the overall operation and safety of a ship, as it involves working with the propulsion machinery, generators, boilers, pumps, and various auxiliary systems that are vital for the vessel's performance. QMEDs are trained to perform maintenance, repairs, and watch-standing duties in the engine room, thereby ensuring that all mechanical systems are functioning optimally and safely.

This hands-on technical role supports the chief engineer and is an integral part of the engineering team on a vessel. A QMED’s responsibilities may include monitoring machinery performance, conducting routine inspections, and carrying out necessary repairs, all of which contribute to the vessel's operational efficiency and safety at sea.
