Question 48Gas Turbine - 1st Asst/Chief

The correct answer is D) 4. The marine gas turbine engine shown in the illustration GT-0024 typically has four lube oil sumps installed. This is in accordance with the design and configuration of most marine gas turbine engines, which require multiple lube oil sumps to ensure proper lubrication and cooling of the various engine components. The other answer choices are incorrect because a marine gas turbine engine would not have 1, 2, or 3 lube oil sumps, as that would not provide the necessary lubrication and cooling required for the proper operation and maintenance of the engine.
