Engine Alarm Monitoring System (AMS / ERAMS) & Sensor Overhaul India
Seanav Marine delivers certified onboard troubleshooting, sensor calibration, and module overhaul for marine Alarm Monitoring Systems (AMS/ERAMS) across all Indian ports. Our instrumentation engineers attend Kongsberg, Lyngso Marine, Nabtesco, and Hyundai AMS installations, resolving sensor loops, analogue input drift, and communication bus faults to restore Unattended Machinery Space (UMS) class notations.
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 Marine AMS Diagnostic & Restoration 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:
-
Communication Bus & Network Topology Audit
Perform signal integrity test on redundant Ethernet, CAN-bus, or Modbus RS-485 serial loops connecting central processing units and distributed I/O racks.
-
Fault Isolation & Defective Module Identification
Interrogate system diagnostic logs to isolate flickering binary inputs, drifting 4-20mA analogue sensor channels, and failing power supply units.
-
Sensor Loop Testing & Signal Calibrator Injection
Inject calibrated current (4mA/12mA/20mA) and resistance signals (Pt100 simulator) at field junction boxes to distinguish field sensor failure from I/O card defects.
-
PCB / I/O Module Replacement & Firmware Verification
Replace defective input/output processing cards with OEM marine-certified spares, restoring channel addressing and parameter setpoints.
-
Dead-Man Alarm & Bridge Telegraph Functional Verification
Perform complete functional trip test of engineer call systems, machinery alarm sirens, and bridge repeater panels, issuing Class UMS restoration report.
24/7 Port & Anchorage Attendance Across India
