Outdoor-Indoor Atmospheric Corrosion in a Coastal Wind Farm Located in a Tropical Island

Atmospheric corrosion is important to consider for energy production and transmission. Important and valuable information have been accumulated in this subject; however, the application of new knowledge obtained is not completed. In order to contribute to a decrease in economic losses caused by atmospheric corrosion in wind farms, studies toward application of this knowledge should be carried out. One of the most common reasons for the failure of coastal structures and infrastructures is deterioration failure which is the result of structure deterioration and lack of project maintenance. Atmospheric corrosion was evaluated at outdoor and indoor exposure sites located at different distances from the sea in a wind farm region. Carbon and galvanized steel, copper and aluminum specimens were exposed. Main pollutants and atmospheric parameters were measured. Significant differences between outdoor corrosivity determined by dose response functions established on ISO standard respecting direct weight loss evaluation were found. Estimation carried out using dose response functions overestimate corrosivity (excepting copper). Main factors causing outdoor corrosion are different to indoor. Very high outdoor and indoor corrosivity classifications were determined.Atmospheric corrosion is important to consider for energy production and transmission.

Atmospheric Corrosion of Reinforced Concrete Steel in Tropical Coastal Regions

The influence of atmospheric parameters and chloride deposition rate on concrete using an atmospheric corrosion approach is rarely found in literature. Seven exposure sites were selected in Havana, Cuba and two at Yucatan Peninsula, Mexico, to expose reinforced concrete samples. Two significantly different atmospheric corrosivity levels have been observed after two years of exposure in Havana depending on atmospheric chloride deposition and the w/c ratio of the concretes. Changes in corrosion current are in accordance with changes in chloride penetration and atmospheric chloride deposition. The influence of sulphur compounds deposition should be considered to study atmospheric corrosion of reinforced steel in concretes either in Havana
