Sea traffic management
 MONALISA - Sea Traffic Management.
|
Sea Traffic Management (STM) is a methodology, developed by the Swedish Maritime Administration MonaLisa project, endorsed by the European Commission, sought to define a set of systems and procedures to guide and monitor sea traffic in a manner similar to air traffic management.
As of December 31, 2004, the International Maritime Organisation established a regulation requiring automatic identification system (AIS) transponders to be installed onboard heavy cargo vessels.
Even though the AIS gives every ship the means to track other ships, they are not able to deduce the intentions of other vessels given only information from the AIS. STM seeks to create an organized traffic management entity called Sea Traffic Coordination Center(STCC) that will act as a central hub maintaining record of all vessels at sea using the AIS and/or radar, enabling the distribution of vessel routes between ship-to-ship and ship-to-shore.
The STCC together with the AIS and/or radar allows:
STM seeks to create safe, efficient and environmentally friendly sea voyages. In order to utilize the full potential of STM, it must be developed to take into consideration the operations carried out at ports and beyond. Ports operations and the efficiency of which, are important factors in performance of the transportation system as a whole. STM can contribute greatly in this area as it was conceived with an emphasis on efficient collaboration between operations at sea and on land.
Ports must smoothly coordinate ships reaching port, departing from port as well as the loading and discharging of ships in relation to inbound and outbound transportation. This means that sea voyages must be in synchronization with port operations such that ship arrivals can be accurately predicted and prepared for. In STM the ambition is to enable this level of operation coordination by improving situational awareness through information sharing. The information needed may be included in the standardized route exchange protocol developed.
