Grit blasting and preservation of the Oosterscheldekering steel doors has started

After the maintenance work on the buttresses of the Oosterscheldekering, the grit blasting and preservation of the 32 steel doors has now started. Preparations for this started more than a year ago; the design and construction of the two innovative screening structures. These structures are required to enable the maintenance work to be performed safely and with no risk of harming the environment. In addition, the revolutionary screening structures resist the natural phenomenon of the North Sea waves and the wind load up to windforce twelve.

Images of the structure

Over the course of the next eight years, every year four steel doors will be entirely grit blasted and provided with a new coating system. This will protect the steel doors for at least 20 years against corrosion. Once the steel door has been preserved again, the rig will be disassembled and moved to the next sluice valve. Aerial photographs have been taken of the wrapped Oosterscheldekering; a picture that provides a spectacular view of the structure needed to treat one steel door.
