Sea water

In order to fix working platforms or wind turbines on the high seas, suction piles are frequently used which can also serve as a foundation. The piles mostly made of steel have a cylindrical shape and are open on one side. With the open side pointing downwards, the suction piles are sucked into the seabed due to the creation of a vacuum and then hermetically sealed. In order to create this vacuum, the seawater situated in the cylinder is pumped from the suction pile. Two Börger pumps are installed on a submersible module and driven by a hydraulic motor. In order to increase the resistance of the pump casing to the aggressive seawater, Börger has developed the Black Protection surface treatment.
