SHORE BASED MAINTENANCE OF GMDSS EQUIPMENT involves the service and upkeep of Global Maritime Distress and Safety System (GMDSS) equipment while the ship is in port or at the shore. The GMDSS system is essential for ensuring vessels can send distress signals and receive weather and navigational information in case of an emergency. Shore-based maintenance ensures that the equipment is operational and compliant with safety standards. This service includes testing communication systems, satellite connections, and backup power to ensure reliability during distress situations.
