Question 1 of 27070

Q

Dual electro-hydraulic steering units usually operate __________.

🔍 Key Concepts

• Redundancy in steering gear systems for safety and regulatory compliance (46 CFR requirements) • How electro-hydraulic steering pumps are arranged on large vessels (duty vs standby) • Purpose of dual units – continuous operation vs backup capability

💭 Think About

• Ask yourself: Is the main goal of having dual steering pumps to increase power at all times, or to ensure steering is still available if one unit fails? • Think about what would normally be running in calm, routine operation versus what happens if a pump or power source fails. • Consider whether the steering system needs both pumps working together to move the rudder, or if one unit alone is normally sufficient.

✅ Before You Answer

• Verify how many independent power units are required by steering gear regulations for seagoing vessels (not the exact CFR number, just the concept). • Check whether normal operations typically use both pumps simultaneously or one in use, one reserved for failure or emergency. • Confirm whether follow‑up gear is normally connected during standard electro‑hydraulic steering operations.
