鹿特丹为一河港,从外海入口处至港内河道全长17海里。外港区最大水深20米,向内逐渐递减为14～12～11.5米。年平均雾日(能见度小于半海里)约为35天。1975年进出港船舶达80,000艘次,平均每天进出近220艘次,船舶航行密度很高。 为满足船舶安全航行和管理上的需要,自河口荷兰湾起,到鹿特丹内港的马斯河大桥为止的鹿特丹水道范围内,共设置了7个港口雷达站,组成了一个连续复盖的雷达链。这个雷达链1957年起全部投入运行。目前,正在进行扩充和技术更新,预计到1980
Rotterdam is a river port, from the sea entrance to the port of the river a total length of 17 nautical miles. The maximum depth of 20 meters outside the port area, inward gradually reduced to 14 ~ 12 ~ 11.5 meters. The annual average fog day (visibility less than half a mile) is about 35 days. In 1975, there were 80,000 inbound and outbound ships, with an average of nearly 220 inbound and outbound trips each day. The ship’s navigation density was high. In order to meet the needs of safe navigation and management of ships, a total of seven port radar stations have been set up within the Rotterdam waterway from the Dutch Gulf of Estuary to the Maas River Bridge in the inner harbor of Rotterdam, forming a continuous covered radar chain. This radar chain has been fully operational since 1957. Currently, expansion and technology updates are in progress and it is estimated that by 1980
