fire, control system failure, emergency stop, or if a turbine over-speed is detected by the
backup system.
8.1.5 Duplex Lube Oil Filter System
The duplex lube oil filter system is supplied with a filter transfer valve and filter differential
pressure indication with alarm. The transfer valve allows a filter transfer to be performed
while the gas turbine is running. The lube oil filter system is contained completely within
the skid. The interconnect piping between the skid edge and the offskid oil cooler, if
applicable, is not provided.
8.1.6 Lube Oil Vent Coalescer
An offskid lube oil vent coalescer is provided to remove oil vapor from the lube oil tank
vent airflow. The coalescer drains trapped oil vapor back to the lube oil tank and allows
the remaining vent airflow to exhaust to the atmosphere. A tank overpressure alarm and
shutdown are also included. The lube oil vent coalescer is loose shipped for offskid
installation by others.
