What is the normal operating capacity of the LO sumo on the starboard side?

• A. 1,747 GAL
• B. 1,800 GAL
• C. 1,700 GAL
• D. 1,752 GAL

Answer: (A)

The amount kept in the lubrication oil sump during normal operation is the volume the system is designed to hold under steady conditions, enough to keep the oil pumps fed and to accommodate small changes in temperature and oil level. For the starboard lubrication oil sump, this nominal operating capacity is 1,747 gallons. This exact figure comes from the ship’s lubrication system design and ensures there’s a reliable oil reserve during startup, steady running, and short transient periods without overfilling or starving the system. The other listed numbers aren’t the standard operating capacity because they don’t match the documented design specification for this sump.
