Question 1 of 27070

On some marine gas turbine reduction gear arrangements, the reduction gear lube-oil supply pump may also supply oil to which of the following components?

🔍 Key Concepts

• Gas turbine reduction gear systems typically have their own dedicated lube oil system separate from the main engine’s system • Think about which components are directly part of, or immediately downstream of, the reduction gear lube oil system • Consider which items listed are normally served by their own pump and system on large marine installations

💭 Think About

• Which of the listed components is physically and functionally most closely associated with the reduction gear itself? • On a typical ship, which of these would be more critical to keep supplied with oil even if the main engine lube system is separate from the gear system? • For each choice, ask: Is this usually part of the main engine lube system, or part of the reduction gear / shafting system?

✅ Before You Answer

• Identify which items are normally in the main engine lube oil circuit versus the reduction gear/shaft line • Recall that filters and coolers can be in-line with a specific pump; check which pump would logically feed them • Focus on the component that must be continuously lubricated when the reduction gear is turning, regardless of the main engine’s own oil system
