🔍 Key Concepts

• Carefully trace the oil supply and scavenge lines in the GT‑0024 diagram and note every component that is actually connected to this lube oil system. • Identify what equipment is shown as being lubricated by this system (gas turbine sumps, transfer gearbox, any gears or bearings) and what equipment is not shown (e.g., main reduction gears, line shaft bearings). • Notice how many pumps are drawn and how they are labeled; determine whether supply and scavenge functions are done by one unit or separate units.

💭 Think About

• For choice (A), look for any piping from the lube oil system to the main reduction gears. Are the main reduction gears even shown on this schematic, or only the transfer gearbox? • For choice (B), ask yourself whether the LOSCA in this figure is drawn as feeding line shaft bearings, or only the gas turbine sumps and transfer gearbox. Where do the lines from LOSCA actually go? • For choice (C), count the distinct lube oil pumps in the diagram and read their labels. Does the schematic show separate supply and scavenge pumps, or one combined "lube and scavenge" pump?

✅ Before You Answer

• Verify whether the main reduction gears appear anywhere in the schematic and whether any oil lines run to them. • Verify whether any line in the figure is labeled or routed to line shaft bearings; if they are not shown, consider what that implies for statement (B). • Confirm from the drawing title on the pump symbol if there is a single combined lube and scavenge pump or multiple separate pumps before deciding among the options.

Which of the following is true concerning the main engine lube oil system of the marine gas turbine shown in the illustration? Illustration GT-0024

Lubrication is provided for the main reduction gears through the transfer gearbox.

The lineshaft bearing lubrication system is provided for by the LOSCA.

The system includes a single combined lube oil supply and scavenge pump.

All of the above.
