-We have a frame 5 gas turbine with a mechanical only-accessory gear box driven hydraulic pump(90 bar).
-The turbine tripped 3 times(within 6 years) before due to the failure of the coupling of the pump.
-What is root cause of coupling failure and what are the recommendations of pump inspection or coupling replacement?
