Common failures & inspection points

Oil level and quality degradation in piston and screw compressor elements due to saltwater corrosion and high humidity in marine engine rooms

Check oil levels weekly and change oil per manufacturer schedule; test for water contamination and sludge formation using ISO 4406 cleanliness codes

Air filter clogging from marine salt spray, sea mist, and particulate matter reducing compressor efficiency and increasing energy consumption

Inspect air intake filters monthly; replace or clean according to pressure differential gauges; verify no salt deposits blocking element

Safety valve malfunction or drift preventing proper overpressure protection (30 bar nominal for LT KE, 7.4-13.8 bar for MAS series)

Test safety valves annually per ASME Section VIII; verify opening pressure with calibrated gauge; document test certificates

Cooling water system failure (sea water or fresh water loops) causing thermal overload in water-cooled LT KE units leading to shutdown

Monitor cooling water flow rate and temperature drop across heat exchanger; inspect water jackets quarterly for scale/blockage; flush with freshwater monthly

Vibration and noise exceeding 91 dB(A) baseline indicating bearing wear, foundation degradation, or element imbalance in piston compressors

Measure vibration monthly using ISO 10816 standards; compare to baseline; inspect bearing clearances and foundation bolts for corrosion
