Maintenance bay
A maintenance bay was an area of a starship, space station, or planetary base where larger vehicles such as shuttlecraft were repaired or serviced.

The primary coolant tanks of Academy trainer crafts could only be refilled in a maintenance bay. In 2368, while wondering why Wesley Crusher had opened the coolant interlock on his flight trainer, Jean-Luc Picard noted this, concluding that it was unlikely that Crusher had done so with that goal in mind.
