This is one of the most common problems seen on all types of ships. Often, compressor capacity can go low or reduced if it is running for a long time and eventually it is unable to cope up with the air demand.
Main reasons for this problem are:
- Leakage in discharge and suction valves.
- Fault or leakage in the unloader.
- Leakage from the relief valve.
- Increase in bumping clearance.
- Wrong setting of compressor auto cut-in and cut-out (too close).
