Aux 1 Unit 10 Q10

1 / 10

In a hydraulically driven transverse thruster, what happens when the directional control valve is activated?

A) The vessel's speed increases

C) The vessel's draft is reduced

D) The propeller stops rotating

B) Hydraulic fluid is directed to the hydraulic motor, causing the thruster propeller to rotate and generate thrust

2 / 10

What component in the hydraulic system controls the direction of the thrust provided by the transverse thruster?

B) The directional control valve

A) The rudder

D) The vessel's speedometer

C) The main engine

3 / 10

Why is it important to regularly maintain the hydraulic system of a transverse thruster?

B) To ensure reliable and efficient operation, prevent leaks, and avoid potential failures that could lead to loss of maneuverability

A) To increase the vessel's speed

D) To eliminate the need for the main propulsion system

C) To reduce the vessel's draft

4 / 10

How is the thrust output of a hydraulically driven transverse thruster typically controlled?

A) By adjusting the vessel's speed

C) By rotating the vessel's main propeller

D) By increasing the vessel's draft

B) By varying the hydraulic pressure delivered to the motor

5 / 10

What is a potential disadvantage of using a hydraulically driven transverse thruster?

B) It can be more complex to maintain due to the hydraulic components, such as pumps, valves, and fluid lines.

D) It increases the vessel's fuel consumption significantly.

A) It provides slower response times compared to electric systems.

C) It offers less precise control over thrust.

6 / 10

What role does the hydraulic pump play in the operation of a hydraulically driven transverse thruster?

B) It generates the hydraulic pressure needed to drive the hydraulic motor that powers the thruster propeller.

C) It reduces the vessel's draft.

A) It controls the direction of the thrust.

D) It monitors the vessel's speed.

7 / 10

What advantage does a hydraulically driven transverse thruster have over an electrically driven one?

B) It provides more immediate and responsive control due to the direct application of hydraulic pressure.

C) It is more complex to operate.

A) It is less powerful.

D) It requires more maintenance.

8 / 10

How is the performance of a hydraulically driven transverse thruster monitored and adjusted from the bridge?

C) By increasing the vessel's speed

D) By rotating the vessel's rudder

B) By using control levers or joysticks that adjust the hydraulic pressure and the direction of fluid flow to the motor

A) By manually adjusting the propeller blades

9 / 10

How does the hydraulic system drive a transverse thruster?

C) By manually rotating the propeller shaft

D) By decreasing the pressure in the hydraulic system

B) By using hydraulic fluid pressure to turn a hydraulic motor connected to the thruster propeller

A) By increasing the vessel's speed

10 / 10

What is the primary function of a transverse thruster on a vessel?

C) To rotate the vessel's propeller

D) To reduce the vessel's draft

A) To increase the vessel's speed forward

B) To provide lateral (sideways) thrust to assist in docking, maneuvering, or holding position
