Common failures & inspection points
Visual inspection through man-holes for sludging, corrosion damage, deposits; check nozzles, cooling tubes, floats, sensors, demister elements. Inspection frequency 6-12 months (doubled under critical conditions). Drydock entrance inspectable (scrubber discharge line).
Periodic test & cleaning of inert gas sample line to O₂ analyser (critical service position). Analyser itself: 2-point calibration (Zero-Gas N₂ 0%, Span-Gas known O₂ concentration) before operation. Calibration accuracy per manufacturer. Alarm setting: >8% O₂ volume.
Check water supply (min. 2 separate pumps required). Visual inspection water level (equipped with low-level alarm). Inspection PMS interval per manufacturer; special attention during IG system shutdown. Check for blockage/corrosion at openings.
Check flame screens/meshes (replacement per PMS plan). Calibration for required pressure values + test at operating pressure. Liquid-filled breakers: check fluid type & level; check anti-freeze additive in case of frost risk. Labelling with opening pressures & fluid type/concentration + min. operating temperature.
Ventil zur Inspection öffnen. Prüfung auf Korrosion, Ventilsitz-Zustand, freie Ventilbewegung über volle Hublänge. Betriebsprobe im Service durchführen. Mindestens zwei Rückschlagvorrichtungen erforderlich (Deck Seal + Isolierventil). Kritisch für Hydrokarbon-Rückfluss-Verhinderung in Maschinenraum.
Access to combustion chamber via hinged front (tool-free accessible — check for wear). Flue gas & recirculation valves regularly stroked (stroke test) when system out of service — ensure free operation over full stroke range. Inspection frequency per operating frequency.
