Aux 1 Unit 9 Q8

1 / 10

In an electro-hydraulic, ram-type steering gear, how is it ensured that the rudder does not exceed the maximum allowable movement?

B) By manually controlling the rudder angle at all times

D) By slowing down the vessel

C) By reducing the hydraulic fluid level

A) By using limit switches that cut off hydraulic pressure when the rudder reaches the set maximum angle

2 / 10

What is the role of the control system in managing rudder movement in an electro-hydraulic, ram-type steering gear?

C) To reduce the hydraulic fluid temperature

A) To monitor the vessel's speed

D) To increase the rudder's movement speed

B) To automatically adjust the rudder angle and stop it at the maximum allowable movement

3 / 10

If the rudder movement exceeds the maximum allowable angle, how is the steering gear system protected from damage?

D) By disengaging the rudder from the steering gear

A) By increasing the hydraulic fluid pressure

C) By reducing the vessel's speed

B) By using mechanical stops to physically prevent the rudder from moving beyond a certain point

4 / 10

According to SOLAS II-I, Regulation 29, what is the minimum rudder angle that must be achieved from port to starboard (or vice versa) within 28 seconds for vessels of 10,000 gross tons and above?

A) 25 degrees to port and 25 degrees to starboard

D) 30 degrees to port and 30 degrees to starboard

C) 20 degrees to port and 20 degrees to starboard

B) 15 degrees to port and 15 degrees to starboard

5 / 10

What is the minimum required rudder angle to which the steering gear must be capable of moving the rudder on both sides, according to SOLAS II-I, Regulation 29?

B) 25 degrees

C) 20 degrees

D) 15 degrees

A) 30 degrees

6 / 10

What additional feature may be incorporated in the steering gear system to protect it from damage if the maximum rudder angle is exceeded?

A) An automatic rudder center mechanism

C) A hydraulic fluid cooler

B) A pressure relief valve that releases excess hydraulic pressure to prevent system overload

D) A speed limiter for the vessel

7 / 10

Why is it critical to have both mechanical stops and pressure relief valves in the steering gear system?

C) To increase the vessel's speed

D) To eliminate the need for regular maintenance

B) To ensure that both mechanical and hydraulic components are protected from excessive forces, preventing damage and ensuring reliable operation

A) To reduce the vessel's draft

8 / 10

What is the purpose of the rudder movement requirement in SOLAS II-I, Regulation 29?

B) To ensure that the vessel can be maneuvered effectively and safely in all conditions

A) To reduce fuel consumption

D) To limit the rudder's movement

C) To increase the vessel's speed

9 / 10

How is the rudder movement requirement tested and verified on a vessel?

D) By measuring the vessel's draft

B) By conducting steering drills during sea trials and routine inspections

C) By reducing hydraulic fluid pressure

A) By adjusting the vessel's speed

10 / 10

For vessels of less than 10,000 gross tons, how quickly must the rudder be capable of moving from 35 degrees on one side to 30 degrees on the other side, according to SOLAS II-I, Regulation 29?

D) Within 30 seconds

A) Within 20 seconds

C) Within 28 seconds

B) Within 15 seconds
