During dry weather operation as RH goes down below 60%, I see a lot of fouling, drop in CDP and drop in load by about 1.5 MW, common on the rest of LM fleet. we do washing very frequently to keep up the compressor clean. has anybody had such experience? during summer humid season this does not happen.

 

I also work with 6000 lm and the weather is quite hot. the pressure plummeted CDP, and sometimes not enough to let the sprint, we found a problem with the throttle.

but I think there are problems with the VIGV actuators.
