Which of the following components are installed in the lube oil system shown in the illustration? Illustration GT-0024

Correct Answer: Option D — all of the above

Marine gas turbine lubrication systems are complex, utilizing pressurized sumps to maintain oil levels, air/oil separators to manage breather emissions, and dedicated supply and scavenge lines. These components ensure continuous lubrication and cooling of high-speed bearings while preventing oil leakage into the gas path or the engine enclosure.
