LM HERMES – Tangier Med - Morocco- KVH V7HTS Antenna Repair, Motor Replacement & System Restoration


LM HERMES - Field Service Dispatch - Maintenance

Tanger Med Port, Morocco | 10–11 December 2025


Project Summary

Global Satcoms completed the KVH antenna repair onboard LM HERMES at Tanger Med.
The service involved diagnosing the KVH system, replacing the antenna motor and belt, correcting LED status faults, restoring modem connectivity, and validating the communication system together with the vessel’s crew.


Vessel: LM HERMES

Location: Tanger Med, Morocco

Service Dates: 10–11 December 2025

Service Scope:

  • KVH Antenna Troubleshooting

  • Motor & Belt Replacement

  • Antenna & Modem LED Verification

  • Voice & Data Validation

  • Remote Support Collaboration

  • Onboard System Testing

Challenges & Operational Constraints

  • Long travel and port entry procedures caused delays.

  • Multiple hours were required for port permits and agent coordination.

  • Engineer remained on standby due to vessel’s berthing schedule.

  • Repair required careful alignment and precise steps guided by remote support.

  • Replacement work had to be completed within the vessel’s short operational window.


Work Completed

The engineer performed all necessary troubleshooting and hardware replacement:

  • Initial LED check showed:

    • Antenna LED: Red

    • Modem LED: Blinking green → solid green after reset

  • Opened KVH antenna housing for inspection

  • Replaced the motor and belt assembly using the supplied spare parts

  • Followed KVH remote support instructions during the replacement

  • Restored antenna stabilization and corrected system LED indicators

  • Completed service testing with crew, including voice/data checks

  • Final verification and job completion reporting
