Aux 1 Unit 9 Q5

1 / 10

Which of the following components might be duplicated in a steering gear system to achieve 100% redundancy?

A) The vessel’s anchor

D) The vessel’s propulsion system

C) The ship’s radar system

B) Hydraulic pumps, control valves, and power units

2 / 10

What is the primary safety benefit of designing a steering gear system to meet single failure criteria?

A) It reduces the vessel's fuel consumption.

C) It increases the vessel's maximum speed.

B) It ensures that the vessel can continue to be safely navigated even if a component of the steering gear fails.

D) It decreases the vessel's turning radius.

3 / 10

Why is 100% redundancy important in steering gear systems on vessels?

B) To ensure that the vessel can still be safely navigated even if a critical component of the steering gear fails

D) To decrease the vessel’s turning radius

C) To reduce fuel consumption

A) To allow for faster steering maneuvers

4 / 10

How does meeting the single failure criteria affect the design of a steering gear system?

D) It eliminates the need for backup systems.

B) It allows the system to be simpler and more compact.

C) It reduces the need for maintenance.

A) It requires the inclusion of redundant or backup components that can take over if a primary component fails.

5 / 10

How does 100% redundancy contribute to the reliability of a steering gear system?

A) By allowing the vessel to steer more quickly

D) By increasing the vessel’s speed

C) By reducing the complexity of the steering system

B) By ensuring that there is no single point of failure that can disable the entire steering system

6 / 10

In a 100% redundant steering gear system, what would happen if one hydraulic pump fails?

B) The redundant pump would automatically engage, and steering would continue normally.

D) The steering system would shut down temporarily.

A) The vessel would lose all steering capability.

C) The steering speed would be halved.

7 / 10

What does the term "single failure criteria" mean in the context of a steering gear system?

B) The system is designed to maintain operational capability even if any single component fails.

C) The system is expected to require frequent maintenance after a single failure.

A) The system is designed to fail completely if any single component fails.

D) The system is only capable of operating at half capacity after a single failure.

8 / 10

Why is the single failure criteria important in the design of steering gear systems?

A) To increase the vessel's speed

B) To ensure that the vessel can still be steered even if a critical component fails, enhancing the safety and reliability of the vessel

D) To simplify the operation of the steering gear

C) To reduce the weight of the steering gear system

9 / 10

What does "100% redundancy" in a steering gear system refer to?

C) The system operates at twice the normal speed.

B) The system includes duplicate components that can fully take over if the primary components fail, ensuring continuous operation.

D) The system requires no maintenance due to its redundancy.

A) The system has double the required power output.

10 / 10

Which of the following best describes a system that meets the single failure criteria?

B) The system is capable of operating normally even if one critical component fails.

D) The system requires manual intervention to operate after a failure.

C) The system is designed to operate at reduced capacity after a failure.

A) The system will fail completely if one component fails.
