In attempting to start the hydraulic pump drive motor of a horizontal electro-hydraulic anchor windlass, what condition would prevent the electric motor from starting?

Correct Answer: Option C — Failure to start could be the result of an electrical interlock associated with the hydraulic pump stroke control being in other than the neutral position.

Electro-hydraulic windlasses utilize electrical interlocks to ensure safe operation. If the hydraulic pump stroke control is not in the neutral position during startup, the motor is prevented from starting to avoid sudden, uncontrolled movement of the windlass, which could cause injury to personnel or damage to the mooring equipment.
