CORROSION PROTECTION FOR WINDMILLS ONSHORE AND OFFSHORE

摘要

The paper describes the basis on which standardisation of the corrosion protection for windmills, erected on land and in the sea, can be regulated and realized. Two essential standards are introduced. The EN ISO 12944, Paints and varnishes - Corrosion protection of steel structures by protective paint systems (1998) and the NORSOK M 501, Surface Preparation and Protective Coating (5. Revision 2004). Referenced coating systems are named and their requirements and criteria for approval are described. The different exposure conditions for on- and offshore for windmills are explained. The need for highly qualified execution of the corrosion protection works, especially for offshore matters, is underlined, and the role of the quality assurance/ quality control in this regard is highlighted. Case histories of successfully realised objects on land and in the sea are presented.
