Together with Rijkswaterstaat, we are working on the next phase of maintenance of the Oosterscheldekering. The hydraulic installations of the storm surge barrier are reaching the end of their technical lifespan and are essential for the controlled movement of the gates.
Different phases
The renovation of these installations is divided into several phases. In phase 1A, we developed the design for the replacement hydraulic installation. This design now forms the basis for the execution of phase 1B.
Testing with 10 installations
At each of the 65 piers of the Oosterscheldekering, two hydraulic installations ensure the controlled movement of the gates. These installations are located in the traffic tunnel beneath the road that runs across the barrier. In phase 1B, we will renovate the hydraulic installations at five piers — 10 of the total 130 installations. As part of this phase, the renovated installations will be tested in practice for one year.
120 installations remaining
If the testing phase in 1B proves successful, Rijkswaterstaat will proceed with phase 2, in which the remaining 120 hydraulic installations will be renovated.
Piping systems
In addition to renovating the hydraulic installations themselves, Hollandia Services is also renovating the steel and stainless steel piping systems of the installations. In phase 1A, the piping at 12 piers was renovated. In phase 1B, 24 piers per year will follow. We are also replacing the steel riser pipes of all 124 cylinders of the storm surge barrier.
Our thanks to Rijkswaterstaat, Van Halteren Technologies, and our other partners for their trust and cooperation. Together, we are committed to ensuring safe and reliable water management in the Netherlands.
