Hello everybody,

My name is Viktor and i am 3rd engineer on LNG carrier vessel,
In our vessel we are using 2x TMC Compressor 1 on duty and the other stand-by,
the problem that we face is that No1 compressor is taking to long to reach the setpoint pressure ( about 10-12 minutes) unlike No2 that needs half of the time( aprox 5 minutes) to reach the same pressure.
We already changed oil, oil filter , oil separators and intake and discharge valve have been overhauled 2 weeks ago but the problem persists.
What else should i check ?
