A gravity type lube oil system for a steam vessel will have a remote pressure sensing device installed on the main lube oil header of the main turbine unit to enable the watch engineer to __________. determine if there is a normal level of lube oil in the gravity tank be certain that the bearings are being adequately lubricated

🔍 Key Concepts

• Function of a gravity lube oil tank in a steam turbine system • Difference between oil level indication (in a tank) and oil pressure indication (in a header or line) • Purpose of a remote pressure sensing device for the watch engineer

💭 Think About

• Ask yourself: What does a pressure sensing device actually measure, and where is it located in this question? • Which of the two statements (I and II) refers to a condition that is directly related to pressure in the header, and which refers to a condition related to level in the tank? • If the watch engineer sees low pressure on the main lube oil header, what problem is he most worried about at that moment?

✅ Before You Answer

• Identify whether pressure in the main lube oil header can tell you the oil level in the gravity tank directly or only indirectly (or not at all). • Confirm that adequate bearing lubrication depends primarily on sufficient oil pressure and flow at the bearings, not just oil existing somewhere in a tank. • Match each statement (I and II) to the type of instrument that would actually be used: level indicator vs pressure indicator.
