Auxiliary Engine Safety Shutdowns & Emergency Generator Testing India
Seanav Marine carries out certified annual safety shutdown calibration and emergency generator auto-start testing at all Indian ports. Our flying squads calibrate mechanical overspeed trips, electronic pickup sensors, low lube oil pressure switches, and high cooling water temp cutouts on Yanmar, Daihatsu, MAN, and Wärtsilä gensets.
Supported OEM Equipment & Multi-Make Coverage
Our marine electronics engineers are factory-trained with proprietary OEM diagnostic interfaces, software keys, and genuine spare parts for leading bridge manufacturers:

Standard 5-Step Generator Safety Shutdown Calibration SOP
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:
-
Electronic & Mechanical Overspeed Trip Testing
Verify mechanical flyweight trip latch and inject frequency signals into electronic pickup unit to verify engine trip at exactly 112-115% rated RPM.
-
Low Lube Oil Pressure Switch Hydraulic Calibration
Calibrate pressure trip transmitters using portable deadweight tester, verifying shutdown solenoid energizes before pressure drops below safe hydrodynamic bearing threshold.
-
High Jacket Water Temperature Cutout Test
Heat temperature sensors in calibrated dry-block bath; verify alarm sounds at 90°C and automatic engine shutdown executes at 95°C.
-
Emergency Fuel Quick-Closing Valve Pneumatic Trip
Test quick-closing fuel shutoff valves from remote fire control station, verifying instantaneous closure within 2 seconds.
-
Class Surveyor Demonstration & Official Endorsement
Witness all generator safety cutouts with attending Class Surveyor; issue comprehensive Calibration Test Report.
