After the 1953 North Sea Flood, the Haringvliet Dam was built as part of the Delta Works. The Haringvliet Dam separates the North Sea from the Haringvliet and connects the islands Voorne-Putten and Goeree-Overflakkee. The "Goereese Sluis" is part of the Haringvliet Dam and is an important shipping link between the Haringvliet and the North Sea, serving fishing, seagoing and recreational vessels.
The lock "Goereese Sluis"consists of three lock heads: an outer lock, an intermediate lock, and an inner lock head. Each lock head has a wooden low- and high tide door on the north and south sides. Each side has an hydraulic system responsible for the movement of the low- and high tide doors with the leveling gates. In total there are six hydraulic systems on the lock. Since the existing hydraulic systems were due for replacement on behalf of  Rijkswaterstaat we renewed them along with all piping and hoses. Our work also included the design of the new hydraulic units and the 3D design of the piping.

Starting in May 2021, SPIE bv in collaboration with DT Hydraulics bv, completed this project entirely within the planned schedule. The on-site project began with the replacement of the hydraulic system at the lock's intermediate head. Next, the hydraulic system of the outer head was renovated, and finally, the inner head. Restrictions applied to the renovation: the lock had to be available to shipping at all times, except during testing periods. Furthermore, the outer and intermediate heads had to be fully available during the storm season (October 15th to April 1st). This planning guaranteed maximum availability of the lock when needed, both for protecting the inland against the sea containment and for shipping traffic passing through the lock "Goereese Sluis".
