Dockmaster

A dockmaster was a person who was responsible for the docking procedures of an outpost.

In 2151, an alien dockmaster informed Captain Jonathan Archer and Subcommander T'Pol that a Klingon K'toch-class scout ship had visited his trade outpost on Rigel X seven days beforehand. While in his control tower, the alien dockmaster monitored the approach vector of Elkan Nine. 

In 2154, Captain Erika Hernandez of the NX class starship Columbia requested clearance to depart from the dockmaster of Starfleet's drydock. 

In 2293, Captain James T. Kirk asked Commander Uhura to hail the dockmaster, so the USS Enterprise (NCC-1701-A) could depart from spacedock. 

A dockmaster aboard Deep Space 9 had an office on the Promenade. (Star Trek: Deep Space Nine set decoration)
