C) Low operating pressure

A) High energy efficiency

D) Low initial cost

B) Ability to withstand exposure to water without significant electrical hazards

2 / 7

Why is a check valve included in the hydraulic circuit of a stabilizer system?

B) To prevent backflow and ensure unidirectional flow

A) To cool the fluid

D) To reduce noise levels

C) To increase the system pressure

3 / 7

Why are hydraulic actuators generally preferred over electrical actuators for vessel stabilizers?

B) They offer greater force and power density, ideal for heavy-duty marine applications

D) They are simpler to maintain than electrical actuators

C) They consume more energy than electrical actuators

A) They are less reliable under continuous operation

4 / 7

In a hydraulic circuit for a stabilizer, which component directs the fluid to control the movement of the stabilizer?

C) Pressure gauge

D) Reservoir

B) Directional control valve

A) Pump

5 / 7

What advantage does a hydraulic actuator have over an electrical actuator in terms of system response?

C) Increased weight and space requirements

B) Faster and more forceful response to load changes

A) Slower response time

D) Lower maintenance demands

6 / 7

What component is essential in a hydraulic circuit for a single stabilizer to maintain constant pressure?

B) Battery pack

C) Electrical resistor

D) Heat exchanger

A) Pressure relief valve

7 / 7

Which of the following best describes the role of an accumulator in a hydraulic circuit for a stabilizer?

C) It cools the fluid before it reaches the stabilizer

D) It acts as a backup motor for the stabilizer

A) It filters the hydraulic fluid

B) It stores energy in the form of pressurized fluid to smooth out pressure fluctuations
