Tilbury Docks impounding pump refurbishment

摘要

The Port of Tilbury is London's major and greenest port and at each high tide the water level inside the impounding dock is raised to meet shipping and operational requirements. This is performed by four 57.5" vertical A/F Vickers Armstrong pumps installed in the late 1960's and over the years they have served the dock extremely well. At any one time three pumps are used, pumping up to 6,000 Litres/sec of aggressive seawater for two hours either side of each high tide.
