The Chief Engineering Officer, simply Chief Engineer, or Ship's Chief Engineer (SCE), was responsible for the repair and maintenance of all systems of starships or stations.

Duties & Functions

This included pre-scheduled preventative maintenance, system upgrades and repairs to correct malfunctioning or damaged systems. The SCE was easily the most demanding officer posting aboard a starship or space station next to the commanding officer, because the chief engineering officer's responsibility was virtually every part of the ship or station, with the exception of the crew.


The SCE was a department head position requiring a rank of Lieutenant or above. On large vessels, the chief engineering officer was usually a Lieutenant commander. If the chief engineer held the rank of captain, then that officer would be known as the captain of engineering.
