Abstract
This article is the third part of a report on a nationally funded project on the performance testing of different corrosion protection systems for offshore wind towers under site and laboratory conditions.1,2 Part 3 deals mainly with the corrosive stress, although researchers found that biological stress may also play a role in the conditions offshore, as described in Part 2 (April 2009 JPCL, pp. 24-34). The corrosive stress includes features such as seawater exposure, wet-dry cycles, temperature variations, construction details (joints, bolts, welds), and construction materials (material combinations). Part 3 of the study discusses the results of the laboratory investigations of several coatings on offshore wind towers and compares them with site testing of the same systems.
