塔林船舶交通服务系统升级现已启动
在十一月底, the 爱沙尼亚n Transport Administration (Transpordiamet) signed off on the Site Acceptance Test (SAT) for the upgrade of the Vessel traffic Services (VTS) system delivered by Saab. 这次升级带来了许多新功能, the most notable being the STM or Sea Traffic Management module that allows end-to-end planning of vessel voyages. STM很重要，因为它旨在将事故发生率降低50%, voyage costs by 10% and fuel consumption by 7% in 2030 compared to 2015. The 爱沙尼亚n Transport Administration is a long-time customer of Saab, 第一笔订单是在近20年前下的.
Other new features are improved traffic display software for the working positions, 新的路由管理功能, integration of AIS route exchange and some technical improvements such as further virtualisation of the software.
具有挑战性的环境
Of all the ports listed in the World Port Index, 塔林 is among the 4.4%的端口被归类为大端口. 然而，规模本身并不能说明一切. 该端口处理各种各样的流量, varying from fast ferries frequently going up and down to Sweden, 芬兰和俄罗斯, 划船消遣的水手. Add to that the cargo and tankers in Muuga port on the other side of the Viimsi peninsula, 对于VTS运营商来说，这确实会很忙.
最重要的是交通, 季节变化很大, 冬天的冰经常出现. This affects radar performance, to which the VTS system automatically adapts. Tides are fortunately quite moderate with often only a meter of difference between high and low tide. 幸运的, because not only do large tidal differences often lead to strong currents, they also affect the dynamic position of the shoreline and the locations where it is safe to navigate.
海上交通管理系统投入运作
One of the main functions of STM is to enable sharing a ship’s intentions of movement, making the shore side a more proactive stakeholder who can issue warnings and suggest actions to ships long before they end up in dangerous or inefficient situations. An essential part of this is the ability to share route information through the Automatic Identification System (AIS). 所有 ships over 300 gross tonnes and passenger ships are required to have an AIS transponder onboard.
下一代AIS系统被称为 vd (甚高频数据交换系统)将允许交换更详细的信息.
With this upgrade, the 塔林 VTS is fully prepared for the future.
