The „Niedersachsenbrücke“ located in Wilhelmshaven serves the landing of hard coal for the coal-fired power stations in Wilhelmshaven as well as for other power stations in Germany. The bridge was finished in 1972 and put into operation. The foundation of this bridge consists of steel pipes, the so-called „bracings“, which are protected against corrosion by a special coating for hydraulic steel work. The first coat was renewed in the years 1982 up to 1984. After a service life of 37 years this corrosion protection system loses its effectiveness and must be renewed. The Helmut Müller GmbH advises and supports the Niedersachsen Ports GmbH & Co. KG in all questions around the topic corrosion protection, coordinates the execution of coating works and super-vises these for the planned construction period of 5 years in total.
