Lube oil quality will affect GTG operation. If lube oil quality does not meet requirement in sampling check, lube oil is required to replace or improve by temporary oil purifier.
But GTG lube oil tank is located inside GT compartment, so GTG lube oil replacement and/or temporary oil purifier is required to connect from outside of GT compartment.
Siemens already provide connection pipe for lube oil tank drain, but not yet provide isolation valve at connection at GT compartment and there is no route for lube oil filling and/or circulating line for temporary oil purifier.
So we would like to clarify GTG lube oil replacement/ temporary oil purifier method under present system. If temporary valve installation is required in method, we will request to install such vale as permanent equipment.
Your prompt action is highly appreciated.
