Successful Inspection of Inert Gas Generator KANGRIM
During a recent onboard attendance, a full operational check and performance verification was carried out on a KANGRIM Inert Gas Generator system, ensuring compliance with safety and operational requirements.
The scope of work included:
- Verification of start-up sequence and safety interlocks
- Assessment of combustion performance and flame stability
- Continuous monitoring of oxygen (O₂) levels at the inert gas outlet
- Functional testing of the control system and analyzer feedback loops
- Inspection of scrubber operation and overall system condition
During operation, a deviation in O₂ readings was identified, with values not fully aligned with expected operating conditions despite stable system performance.
Further investigation confirmed that the deviation was related to analyzer drift, a known and common characteristic in oxygen measurement systems over time.
Corrective actions involved:
Fine zero and span adjustment of the O₂ analyzer (Xendos 1800)
Verification of analyzer response using reference conditions
Validation of signal stability and control system feedback
Following the adjustments, the analyzer response was restored, providing stable and accurate O₂ readings within required limits. The system was subsequently verified to operate safely and reliably under normal conditions.
Routine calibration and verification of oxygen analyzers remain essential to ensure the accuracy and integrity of inert gas systems in marine applications.
