Question 1030 Deck Safety

70% to pass

If one hydraulic pump of an electro-hydraulic steering unit fails, the vessel's steering can initially be maintained by activating which of the following units?

A telemotor
B trick wheel
C accumulator
D standby pump
AI Explanation

The correct answer is D) standby pump. In an electro-hydraulic steering system, the standby pump is designed to automatically activate and maintain steering control if one of the primary hydraulic pumps fails. The standby pump provides a redundant source of hydraulic pressure to keep the steering system operational. The other options are incorrect because: A) a telemotor is a mechanical steering system, not relevant to an electro-hydraulic setup; B) a trick wheel is a manual backup steering wheel, not an automatic redundant system; and C) an accumulator stores hydraulic pressure, but does not actively pump fluid like a standby pump.
