Which device must a ship equipped for GMDSS have to meet safety regulations?

To meet safety regulations under the Global Maritime Distress and Safety System (GMDSS), a ship must be equipped with a tailored communication unit that includes Digital Selective Calling (DSC) functionality. DSC allows for automated distress alerts and individual ship-to-ship or ship-to-shore communications, significantly enhancing safety communication in emergencies. This technology ensures that distress signals can be sent with high precision and reliability, facilitating rapid response from search and rescue services.

While a standard VHF radio is also important for maritime communications, it does not encompass the advanced capabilities required by the GMDSS, particularly the automated distress alerting provided by DSC. A global positioning system (GPS) is beneficial for navigation but is not a requirement specifically for communication under GMDSS regulations. Additionally, while a signal flares kit is useful for visual distress signaling, it does not fulfill the electronic communication requirements mandated by GMDSS standards. Thus, the tailored communication unit with DSC functionality is essential for compliance and ensuring vessels can effectively communicate and respond to maritime emergencies.
