D The output pressure from the hydraulic pumps is too high.

Tanong 4

When a heavy sea strikes the rudder, which one of these statements best describes what will happen?

A If the force is large enough, the hydraulic pressure in the steering gear will be high enough to operate the safety valve, and the rudder will move.

B The rudder is free to move, but the auto-pilot will bring the ship back on course.

C The rudder is hydraulically locked in position and will not move.

D The shape and lightweight design of the rudder means that wave forces have no effect.

Tanong 5

For an electro-hydraulic steering gear, if the stand by pump fails to start following a failure of the running pump, which one of the following best describes the likely cause?

A The pump has not been set to standby or its power supply has been switched off.
