Outline of VTS

The VTS(Vessel Traffic Service System) is a ship movement service system. It provides necessary information or advice for safe navigation using the latest scientific equipment such as Radar, AIS, VHF or CCTV to promote the safety and efficiency of ship movement and to protect the environment. This is done within a scope which does not violate the rights of the masters but not him absolve from obligations to observe the port and navigation ship movements through the channels. This raises the efficiency of port management and as a result, the distribution becomes smoother and the VTS comes to contribute to the national economic profit.
