Performance and behaviourPerformance and behaviour

Challenge for Gas supply system: QCO of one ore more engines.Gas pressure fluctuation in the range of 0,5 bar due to the volume of gas pipe between compressor and GVU. No impact onthe other engines

No indication of load hunting (swinging), stable load on each engine Cleaning of combustion chamber after HFO operation takes
