Standard 5-Step Marine Radar & ECDIS Overhaul 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:

  1. Pre-Arrival Performance Diagnostic & Fault Log Analysis

    Analyze Master's radar error logs, check PM (Performance Monitor) readings, and cross-reference target detection range dropoffs.

  2. Transceiver Overhaul & Magnetron Replacement

    Discharge high-voltage capacitors safely, replace worn magnetron and limiter diodes, and perform frequency auto-tune sweep.

  3. Scanner Gearbox & Heading Alignment Calibration

    Inspect antenna turning gearbox oil levels, check drive belt tension, test safety interlock switch, and align heading marker to 0.1° accuracy.

  4. ECDIS NMEA Feed & Chart Presentation Audit

    Verify Gyro, GPS, Speed Log, and AIS sensor feeds into ECDIS dual stations; test safety contour depth alerts and ENC update permits.

  5. Sea-Trial Performance Verification & Service Report Endorsement

    Execute PPI display sea-clutter and rain suppression checks on live harbor targets; issue Class-compliant technical service report.
