What is the purpose of a high-mounted fuel tank? Is it only used in emergency situations?
It’s like this: I’m not in this field, but I’ve asked former engineers from my previous workplace before
It is mainly used to supply oil to the unit’s lubrication system for a short period of time in the event of an emergency shutdown.
A sudden power outage occurred throughout the plant; the oil pumps stopped working, and the oil pressure dropped. At this point, the auxiliary high-level oil tank can maintain the oil pressure for a while relying on gravity...
The main function of the high-level oil tank is to ensure that the lubrication pump can provide oil pressure to the compressor or pumps in the event of a power outage.

There are many posts related to the function of the high-level fuel tank; searching for “high-level fuel tank” will yield numerous results. Below are a few links that I found. 1. The specific function of the high-level oil tank in high-speed centrifugal compressors. 2. The differences in function between the emergency oil pump and the high-level oil tank
Under normal conditions, the main and auxiliary oil pumps at the fuel station supply lubricating oil to the unit’s equipment. In the event of a failure, these pumps stop working and the unit shuts down; at this point, the oil stored in the high-level oil tank flows into the lubrication system, ensuring an adequate supply of lubricant for the bearings during the 5–7 minutes during which the rotor continues to rotate slowly. Prevent bearing and rotor damage caused by fuel interruption.
To ensure the lubrication of the bearings during the engine’s idle operation after a sudden power outage or a failure in the lubricating oil system (disruption in lubricant supply).
The high-level oil tank is used to supply oil to the unit in the event of an accident when the unit is running at idle speed. Thereby ensuring the safe shutdown of the unit. The capacity should generally ensure a fuel supply duration of at least 10 minutes~~
It is mainly to give several groups some time to stop in the event of an accident, so as to prevent things like tiles from being burned
Primarily, in the event of a failure of the main pump and the auxiliary pump being unable to start on its own, the unit shuts down, thereby ensuring a sufficient coasting time for the unit and allowing lubricant to be supplied for a while longer.
