Large vessels sometimes use electrical propulsion motors, the electrical power being provided by a diesel generator. Noise and vibration of electric motors include, besides mechanical and aerodynamic sources, an electromagnetic source due to electromagnetic forces which is responsible for the "whining noise" of the motor.

A repair ship is a naval auxiliary ship designed to provide maintenance support to warships. Repair ships provide similar services to destroyer , submarine and seaplane tenders or depot ships , but may offer a broader range of repair capability including equipment and personnel for repair of more significant machinery failures or battle damage.
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
Xanthus-class vessels provided a diverse range of auxiliary repair functions for both the US and British navies. American-flagged ships served in the Pacific with the US Navy, repairing ships damaged in the final battles against Japan.
