Total questions: 15
Worksheet time: 8mins
What can result from leaking hydraulic lines or seals in the steering gear system?
Increased steering speed
Sluggish or unresponsive steering
Better lubrication
Higher hydraulic pressure
What is a common consequence of insufficient hydraulic oil?
Rudder synchronization
Motor burnout
Cavitation and overheating
Stronger hydraulic force
Contaminated hydraulic oil can lead to:
Increased oil viscosity
Valve blockages and pump failure
Better system cooling
Stronger pressure build-up
Power supply failure in the steering system mainly affects:
Emergency alarms
Rudder stock lubrication
Steering motors and control systems
Hydraulic oil filtration
A faulty solenoid in the steering gear can cause:
Fast motor cooling
Disrupted valve or motor activation
Increased hydraulic pressure
More efficient rudder movement
Excessive wear or misalignment of the rudder stock may result in:
Improved steering response
Impaired steering capability
Automatic rudder realignment
Reduced ship drag
A jammed or stuck rudder is often caused by:
High-quality lubrication
Foreign objects, ice, or obstructions
Electrical short circuits
Oversupply of hydraulic oil
Sheared pins or bolts in the steering system typically result from:
Insufficient hydraulic pressure
Excessive torque or misalignment
Air ingress into hydraulic lines
Poor electronic feedback
Overheating of steering motors is commonly due to:
Low oil levels
Generator overcapacity
Overuse, lack of cooling, or poor maintenance
Power surplus
What happens if directional control valves fail?
Faster rudder movement
Hydraulic fluid flows properly
Hydraulic fluid flow to actuators is blocked
Emergency steering activates automatically
A faulty feedback mechanism in the steering gear system may cause:
Correct rudder positioning
Erratic or incorrect rudder actions
Overheating of the hydraulic oil
Instant correction by the system
Air ingress into hydraulic lines results in:
Smoother motion
Erratic motion or loss of control
Decreased cooling needs
Better pressure buildup
Excessive heat in hydraulic systems can:
Improve oil viscosity
Cause oil viscosity to decrease and damage components
Automatically cool down motors
Reduce hydraulic system efficiency temporarily but safely
An incorrect reading from a rudder angle indicator can:
Enhance rudder performance
Mislead the operator about rudder position
Stabilize rudder response
Improve ship navigation accuracy
Non-functional emergency controls during emergency steering are often due to:
Over-testing
High-pressure build-up
Improper maintenance or lack of testing
Rudder realignment
