Flue Gas Inert Gas Generator

• Area: Scrubber fouling, corrosion, blocked spray nozzles, demister damage
  Check: Visual inspection through scrubber manholes; check spray nozzles for blockage (impairs cooling efficiency); inspect cooling pipes, floats, sensors for corrosion or soot deposits; verify cooling water flow and demister function
• Area: Deck seal water level loss, gauge glass fouling, seal integrity compromise
  Check: Verify gauge glass is clean and water level visible; check high/low level alarm float switches operational; inspect for water leakage, corrosion; in cold weather verify heating coil function and trace heating active; confirm low-level alarm functions
• Area: P/V breaker seal loss, incorrect relief pressure setting, glycol/water mixture degradation
  Check: Verify P/V breaker opens at preset pressure/vacuum; check sight glass and fluid level (glycol-water mixture); inspect for leakage around valve stem; test differential pressure response; replace fluid if discolored/contaminated
• Area: Oxygen analyzer drift, calibration loss, sensor fouling or failure
  Check: Calibrate analyzer ≥24 hrs before cargo operations; log calibration results; verify O2 readout 2-4% during operation; replace probe/sensor if drift >0.5%; ensure analyzer sample line clear and inlet not fouled
• Area: Combustion process inefficiency, incomplete fuel combustion, soot generation
  Check: Observe flue gas color (should be colorless/light gray, not black); monitor fuel/air ratio; inspect burner nozzles and air registers for clogging; verify combustion oxygen ≤4%; check fuel pump pressure/flow; inspect ignition electrode condition
• Area: Non-return valve (check valve) function loss, backflow risk to engine room
  Check: Confirm non-return valves at deck seal outlet prevent backflow; verify pressure differential across deck seal maintained; listen for flow disturbance; schedule valve seat/seal inspection per Condition Audit; test with pressure gauge if vessel equipped

• Area: Oxygen analyzer drift, calibration loss, sensor fouling or failure
  Check: Calibrate analyzer ≥24 hrs before cargo operations; log calibration results; verify O2 readout 2-4% during operation; replace probe/sensor if drift >0.5%; ensure analyzer sample line clear and inlet not fouled
• Area: Combustion process inefficiency, incomplete fuel combustion, soot generation
  Check: Observe flue gas color (should be colorless/light gray, not black); monitor fuel/air ratio; inspect burner nozzles and air registers for clogging; verify combustion oxygen ≤4%; check fuel pump pressure/flow; inspect ignition electrode condition
• Area: Non-return valve (check valve) function loss, backflow risk to engine room
  Check: Confirm non-return valves at deck seal outlet prevent backflow; verify pressure differential across deck seal maintained; listen for flow disturbance; schedule valve seat/seal inspection per Condition Audit; test with pressure gauge if vessel equipped

• Area: Scrubber fouling, corrosion, blocked spray nozzles, demister damage
  Check: Visual inspection through scrubber manholes; check spray nozzles for blockage (impairs cooling efficiency); inspect cooling pipes, floats, sensors for corrosion or soot deposits; verify cooling water flow and demister function
• Area: Deck seal water level loss, gauge glass fouling, seal integrity compromise
  Check: Verify gauge glass is clean and water level visible; check high/low level alarm float switches operational; inspect for water leakage, corrosion; in cold weather verify heating coil function and trace heating active; confirm low-level alarm functions
