Under this contract, Transas replaced the previous Vessel Traffic Service (VTS) system with the Transas Navi-Harbour system. The Navi-Harbour VTS system is specifically designed to ensure maritime navigation safety and efficiency, while at the same time protecting the environment from the possible adverse effects of marine traffic. The new Transas VTS installed makes use of the latest sensors like Radar, CCTV and AIS to provide comprehensive and reliable visibility of the marine traffic situation in and around the port. The system consists of two operator workstations, one recording and playback station and three VHF stations which are all used by the port authority to manage and monitor the marine traffic in their area of responsibility. In addition to this, the system includes an online portal allowing authorized users to view, in real time, the marine traffic in the port and the surrounding areas. Bahia Blanca Port is the second largest port in Argentina. Strategically located between La Pampa and Patagonia, it mainly consists of Ingeniero White and Galván harbors and serves as an important communications hub for the country. The new VTS system by Transas is being considered to strengthen the port, improve quality of its services and optimise resources utilisation.
