Quartermaster
Replicator usage can allow the fabrication of nearly any critical mission part, but large-scale replication is not considered energy-efficient except in emergency situations. However, in such situations, power usage is strictly limited, so it is unwise to depend upon the availability of replicated spare parts.
Thus a ship/facility must maintain a significant stock of spare parts in inventory at all times. The Quartermaster (Starbase) is the person responsible for the requesting of parts from Starfleet and maintaining the stock and inventory of all spare parts. All request for supplies are passed to the Quartermaster (Starbase), who check and send the final request to the Chief Operations Officer and Executive Officer for final approval. A good Quartermaster is never caught short on supplies.
The Quartermaster is part of the Operations chain of command reports to the Chief Operations Officer.
The afloat equivalent of the Quartermaster (Starbase), is a Stores Petty Officer.
NOTE: This is not to be confused with Quartermaster (Ship)
