In the process of planned shutdown of the GE frame 9E gas turbine, it failed to transfer from light crude oil to distillate fuel oil at 13mw. Investigation revealed that there was a spurious fire alarm. This may have affected the inability to transfer from LCO to DFO prior to shutdown. Also the bearing lift oil hose was found to have punctured resulting in lift pressure of 18psi. Shaft was left in standstill position when after staying at 6rpm for 80 minutes, the turning gear disengaged.
How does one go about the process of placing the gas turbine on turning gear again as part of restoring it to service?
