1 / 10

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

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

C) It offers less precise control over thrust.

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

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

2 / 10

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

B) By varying the hydraulic pressure delivered to the motor

C) By rotating the vessel's main propeller

D) By increasing the vessel's draft

A) By adjusting the vessel's speed

3 / 10

How does the hydraulic system drive a transverse thruster?

D) By decreasing the pressure in the hydraulic system

A) By increasing the vessel's speed

C) By manually rotating the propeller shaft

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

4 / 10

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

C) It is more complex to operate.

D) It requires more maintenance.

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

A) It is less powerful.

5 / 10

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

D) The vessel's speedometer

C) The main engine

A) The rudder

B) The directional control valve

6 / 10

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

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

A) The vessel's speed increases

7 / 10

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

A) By manually adjusting the propeller blades

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

C) By increasing the vessel's speed

8 / 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

C) To reduce the vessel's draft

D) To eliminate the need for the main propulsion system

9 / 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

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

A) To increase the vessel's speed forward

10 / 10

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

D) It monitors the vessel's speed.

A) It controls the direction of the thrust.

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

C) It reduces the vessel's draft.
