Referring to the illustration of a twin-screw diesel-electric AC propulsion drive system, if either the port propulsion excitation transformer or the port propulsion field controller was inoperable, what statement is true? Illustration EL-0164

Question

Accepted Answer

Either the standby excitation transformer and standby field controller or the starboard excitation transformer and starboard field controller could be used to control the field of the port propulsion motor.

Answer

The standby excitation transformer and standby field controller could be used to control the field of the port propulsion motor, and this would be the only means of backup.

Answer

The port propulsion drive motor would be inoperable, as no means of field control is provided as a backup.

Answer

The starboard excitation transformer and starboard field controller could be used to control the field of the port propulsion motor, and this would be the only means of backup.
