Midterm Quiz 3

What is the primary function of a hydraulic steering gear system?

• To generate electrical power

• To use hydraulic pressure for rudder movement

• To rotate the ship’s thrusters 360 degrees

• To manually adjust the rudder

Which component in an electro-hydraulic steering gear system powers the hydraulic pump?

• Hydraulic cylinder

• Electric motor

• Rudder stock

• Azimuth thruster

Why are azimuth thrusters commonly used in dynamic positioning (DP) vessels?

• They reduce fuel consumption

• They require minimal maintenance

• They provide 360-degree maneuverability

• They increase the vessel’s speed

Which type of steering gear system combines electrical and hydraulic components for better efficiency?

• Hydraulic steering gear system

• Electro-hydraulic steering gear system

• Azimuth thruster system

• Mechanical steering gear system

What is the main advantage of azimuth control over conventional rudder systems?

• It operates entirely on hydraulic pressure

• It allows movement in any direction without changing the ship’s heading

• It requires less power than other systems

• It eliminates the need for electronic controls
