Challenge
The Eastern Scheldt (Oosterscheldekering) is a series of dams and storm surge barriers protecting the Netherlands from flooding from the North Sea. Part of a renewable energy project included the installation of five tidal turbines on the storm surge barrier. Huisman Equipment was tasked with the construction of steel structure to mount the tidal turbines to the barrier. Installation of the Tidal Power Plant needed to be completed with precision and pace. Changes in the water levels and the tide required the entire installation be complete in a two hour window.
Solution
The 500 ton steel structure was floated on a barge to the storm surge barrier. Enerpac developed together with Huisman Equipment 4 custom 400 ton double-acting CLRG hydraulic cylinder with tilt saddles, these saddles were integrated into the steel mounting structure. During the positioning of the tidal turbines the cylinders applied a precise amount of tension in order to mount the structure securely on the storm surge barrier. The Tidal Power Plant was successfully mounted on the barrier and will be producing clean, hydroelectric power.
