The primary responsibility of a Qualified Member of the Engine Department (QMED) is the operation and maintenance of machinery aboard a vessel. QMEDs play a crucial role in ensuring that all mechanical systems, including engines, pumps, and other machinery, are functioning efficiently and safely. They perform routine maintenance, troubleshoot issues, and carry out repairs to keep the machinery operational, which is vital for the overall performance and safety of the vessel.

In contrast, navigation of the vessel is typically the responsibility of officers in the deck department. Management of crew safety drills is overseen by designated safety officers or the vessel’s master, ensuring that all crew members are familiar with emergency protocols. Additionally, overseeing cargo operations falls under the jurisdiction of the deck department, which manages loading, unloading, and securing cargo to ensure it is done safely and in compliance with regulations. Each position has specific duties, but the QMED’s expertise is fundamentally tied to machinery operation and maintenance.
