Inspection

Inspector Detail

Common issues

  • Scrubber tower packing fouling with soot/particulate, reducing SO2 and particulate removal effectiveness
  • Deck water seal running low or blocked, allowing possible backflow of flue gas toward the engine/boiler uptake
  • O2 analyzer drift or sensor fouling giving falsely low O2 readings
  • Fan/blower bearing wear from continuous duty in a moist, corrosive gas stream
  • Non-return valve sticking closed or open due to soot/scale deposits
  • Corrosion of ductwork and scrubber shell from wet, acidic flue gas condensate
  • Deck seal water pump failure or strainer clogging
  • Automatic deck isolating/pressure control valve sticking or slow to respond

Inspection checklist

  • Verify O2 content at the deck seal outlet with an independent portable analyzer, cross-checked against the fixed unit
  • Check scrubber water flow, drainage and general condition
  • Function-test deck water seal level and float switches
  • Function-test non-return valves and the pressure/vacuum breaker
  • Trend blower vibration and bearing temperature
  • Inspect ductwork and scrubber shell for corrosion, with spot wall-thickness checks in known wear areas
  • Test the high-O2 alarm and automatic shutdown/isolation sequence
  • Confirm remote/mimic panel readings match local instruments
  • Check deck seal water supply pump changeover and low-level alarm

Service intervals

Deck seal water strainercleaned weekly and after each use
O2 analyzer calibrationmonthly, per manufacturer's procedure
Scrubber packing inspectionannually or per class requirement
Blower bearing condition checkper running-hour interval in the maker's manual, commonly every 2000-4000 hours
Non-return valve overhaulat each dry-docking or class survey
Full IGS function test (high-O2 alarm, automatic shutdown)before each cargo operation requiring inert gas

Typical wear limits

Deck seal water levelmaintained within the range marked on the unit's own nameplate/manual - confirm the specific figure there
Non-return valve seat leakageno visible leakage past the seat during the manufacturer's static pressure test procedure
Ductwork wall thicknessassessed against original as-built thickness per class CSM requirements - typically renewal is considered around a 10-20% reduction, confirm with class

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • O2 analyzer sensor/cell
  • Deck seal water level float switch
  • Non-return valve seat/disc set
  • Blower bearing set
  • Scrubber spray nozzles
  • Deck seal water pump seal kit

Safety

  • Flammable atmosphere risk in cargo tanks if O2 exceeds the safe limit undetected - never bypass the O2 alarm/trip
  • Hot flue gas duct and scrubber surfaces present a burn hazard
  • Confined space entry required for internal inspection of the scrubber tower/deck seal
  • Backflow of flammable gas toward the engine/boiler room if a non-return valve fails

Class survey

IGS is normally within the Continuous Survey Machinery (CSM) or annual survey scope on tankers. Class will want function-test records for the high-O2 alarm/trip, deck seal operation and non-return valve integrity, plus traceable O2 analyzer calibration records.

Estimated lifetime: Deck seal and scrubber shell components typically last 15-20 years with proper corrosion control; blower/fan units are often overhauled or replaced within 10-15 years. Actual life depends strongly on flue gas sulfur content and maintenance quality.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
