A system and associated method for protecting during a shutdown a turbine having a turbine shaft and a compressor driven by the turbine shaft. The system include a first lubrication system, a second lubrication system, and a control system. The first lubrication system is configured to provide lubrication to the compressor. The second lubrication system is configured to provide lubrication to the turbine. The control system monitors the rotation of the turbine shaft in response to a shutdown request and causes the first and second lubrication systems to provide lubrication to the turbine and compressor until and after the turbine shaft stops rotating. The control system causes the first lubrication system to provide lubrication for a first predetermined period of time after the turbine shaft stops rotating. The control system causes the second lubrication system provides lubrication for a second predetermined period of time after the turbine shaft stops rotating. If the turbine shaft starts to rotate any time after it has stopped, the control system causes the first and second lubrication systems to provide lubrication to the turbine and compressor until and after the turbine shaft stops rotating again.
