Global Maritime Safety and Maritime Safety (GMDSS) was developed by the maritime nations within the framework of the International Maritime Organization (IMO). It is the result of the adoption of amendments in 1988. to the International Convention for the Protection of Life at Sea (SOLAS) of 1974.
The GMDSS is designed to provide maximum accessibility of communications related to the safety of all ships, passenger and cargo, with a gross tonnage of 3,000 tons that are on international flights. For vessels with a tonnage of less than 300 reg., As well as those not involved in international flights, the requirements of the administration of their national flag apply.
To ensure maximum safety of navigation, the latest developments in the field of maritime communications, such as satellite systems and digital technologies, are used. The GMDSS guarantees the provision of appropriate vessels with communication with coastal services in case of emergency situations and for the exchange of safety information, around the clock and at any location.
The GMDSS divides the world's oceans into 4 marine regions based on the location and communication capabilities of coastal stations: A1, A2, A3 and A4. The figure shows an example of European marine areas.
