Standard 5-Step OMD Calibration & Inspection Protocol
Our Class-approved technicians execute this standardized procedural workflow to ensure first-time compliance with attending Class surveyors and Indian Port State Control (PSC) inspectors:
-
Sampling Line Blow-Down & Cyclone Separator Cleaning
Clear crankcase sampling pipes of oil condensation using dry compressed air; clean condensation U-tubes and sintered filters.
-
Optical Measuring Cell Inspection & Prism Cleaning
Clean infrared transmitter prisms and receiver photodiodes; replace deteriorated sealing O-rings.
-
Zero Baseline Balance & Optical Opacity Verification
Perform electronic optical balance check in clean air to establish precise zero reference without false positive alarms.
-
Calibrated Smoke / Optical Filter Linearity Check
Introduce calibrated test filters to verify alarm threshold triggers at prescribed mg/L oil mist density with engine slowdown relay trip.
-
Class Certificate of Calibration & Engine Trip Endorsement
Issue official Calibration Certificate detailing optical sensitivity, suction fan vacuum level, and engine emergency trip integration.
