On commission from Engie, we supplied Rijkswaterstaat with new ballast resistors for the Topshuis, the operations building of the Oosterscheldekering flood barrier. The Oosterscheldekering is the biggest and most famous part of the Delta Works. This 9km-long storm surge barrier shuts off the Oosterschelde estuary mouth when there is a threat of high water levels and is operated from the ir. J.W. Topshuis, the operations building on the Neeltje Jans artificial island.
At present, Rijkswaterstaat is working on a full renovation of the Oosterschelde barrier, including the power supply. The power supply of this structure is separate and is not connected to the national grid, so that there is always power available to operate the sluices. The power is supplied by diesel generators. Ballast resistors are necessary in order to be able to test these generators. The old resistors had a steel casing but were completely damaged by the salt air. Batenburg Mechatronica therefore supplied ten new ballast resistors entirely enclosed in a stainless steel casing. This ensures that the generators can be tested safely for the next 30 years.
