CORROSION PROTECTION OF THE OERESUND CROSSING BRIDGES

The Oeresund crossing provides a fixed link between Malmoe, in Southern Sweden and Copenhagen in Denmark. The link is made up of a tunnel from the Danish side to an artificial island; the link then becomes a series of bridges from the island to Sweden. There are three bridges, the East and West approach bridges and the high bridge. The bridges carry a dual carriageway road on the top deck and a twin track railway on the lower deck. The deck is a composite steel and reinforced concrete structure. The concrete forming the deck structure and the steel the side trusses. This paper details the approach to corrosion protection to the internal and external surfaces of the steel structure. It outlines the selection of specifications for protection and provides details of how different fabricators achieved the specification requirements. In particular it considers the impact of fabrication procedures on the quality of applied coating and the need for repair and reinstatement of coatings on site. The paper also considers specific concerns relating to this project, in particular: Coating of site connections in-situ over the sea; The need to use the same paint materials in a wide and extreme range of environmental conditions; The requirement to transport by sea faring barge completed bridge beams such that damage was minimised.
