Aux 1 Unit 9 Q5

Correct Answer: B) Hydraulic pumps, control valves, and power units

Explanation: To achieve 100% redundancy, critical components of the steering gear system, such as hydraulic pumps, control valves, and power units, are duplicated. This ensures that if any one of these components fails, the backup can take over without loss of steering control.

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

Explanation: The single failure criteria are important because they ensure that the vessel remains steerable even if a critical component of the steering gear fails. This is crucial for the safety and reliability of the vessel, particularly in emergency situations.

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

Explanation: A system that meets the single failure criteria is capable of operating normally even if one critical component fails, ensuring continuous operation without manual intervention or significant reduction in performance.

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

Explanation: 100% redundancy is important because it ensures that the vessel remains navigable even in the event of a critical component failure, which is essential for the safety of the ship and its crew.

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

Explanation: The primary safety benefit of designing a steering gear system to meet single failure criteria is that it ensures the vessel can still be safely navigated even if a critical component fails, which is essential for the safety of the ship, crew, and cargo.

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

Explanation: 100% redundancy increases the reliability of the steering gear system by eliminating single points of failure. If one component fails, the redundant component takes over, preventing the entire system from being disabled.

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

Explanation: 100% redundancy means that the steering gear system is designed with duplicate components, such as pumps, hydraulic circuits, and controls, so that if the primary system fails, the secondary system can immediately take over, ensuring that steering is maintained without interruption.

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

Explanation: To meet the single failure criteria, the steering gear system must include redundant or backup components, such as additional pumps, control systems, or power supplies, that can take over if a primary component fails.

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

Explanation: Single failure criteria mean that the steering gear system is designed to continue functioning even if one component fails. This ensures that the system can still operate safely and effectively without a complete loss of steering control.

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

Explanation: In a 100% redundant system, if one hydraulic pump fails, the redundant pump automatically engages, allowing the steering system to continue operating without interruption.
