“…At low temperatures, organic systems exhibit changes in their response, transitioning between plastic–elastic and elastic–plastic behavior, while also experiencing increased rigidity modulus, altered hardness, and susceptibility to cracking. Under these conditions, the adhesion of the paint system to the substrate tends to decrease, along with its impact resistance, abrasion resistance, and corrosion resistance [ 5 , 6 , 7 ].…”

This study evaluated the behavior of three paint systems exposed to the Antarctic marine environment for 45 months compared to a control of uncoated carbon steel with a determined corrosion rate. At the study site, all environmental conditions, solar radiation, and the concentration of environmental pollutants (Cl− and SO2) were evaluated. The paint systems differed in terms of the primer and top coat. Coated samples were studied before and after exposure. They were evaluated visually and using SEM to determine adhesion, abrasion, and contact angle; using the Evans X-Cut Tape Test; using ATR-FTIR spectroscopy to analyze the state of aging of the top layer; and using electrochemical impedance spectroscopy (EIS) for coat protection characterization. The corrosion rate obtained for steel was 85.64 µm year−1, which aligned with a C5 environmental corrosivity category. In general, the evaluation in the period studied showed the paint systems had good adhesion and resistance to delamination, without the presence of surface rust, and exhibited some loss of brightness, an increase in the abrasion index, and a decrease in the percentage of reflectance due to aging. EIS showed good protection capability of the three coating schemes. In general, this type of paint system has not previously been evaluated in an extreme environment after 45 months of exposure to the environment. The results showed that the best behavior was found for the system whose top layer was acrylic–aliphatic polyurethane.

“…Furthermore, protective coatings to prevent corrosion in the Arctic environment are currently under development, but this is challenging because organic materials change from elastic to plastic under low-temperature conditions and cracks in the coating can form because of iceberg impact. 15 Therefore, consideration of possible corrosion is required for structural steels, and this preferable to the coating technique. Unfortunately, there are currently no studies of the corrosion of the steels used in the Arctic offshore structures in the submerged and splash zones.…”

“…Nevertheless, no trends were established to roughness or wettability parameters. Improved behaviour was obtained for a three-layer system with high thickness (1400 µm), consisting of two glass-flake reinforced epoxy coats and a polyurethane topcoat [143,144]. Momber, also in 2016 [74], reported a study about the assessment of deterioration of protective coatings and exposed steel surfaces on offshore wind power platforms in the North Sea and the Baltic Sea.…”

“…The authors assessed the corrosion performance of the coatings, tested the coatings adhesion, performed hoarfrost accretion measurements, resistance, abrasion and wettability tests. The test conditions were adapted to Arctic offshore conditions covering low temperatures down to −60 • C [143,144]. The results indicated that if exposed to very low temperatures, the coatings change their response to corrosive and mechanical impact loads.…”

Concerns over reducing CO 2 emissions associated with the burning of fossil fuels in combination with an increase in worldwide energy demands is leading to increased development of renewable energies such as wind. The installation of offshore wind power structures (OWS) is one of the most promising approaches for the production of renewable energy. However, corrosion and fatigue damage in marine and offshore environments are major causes of primary steel strength degradation in OWS. Corrosion can reduce the thickness of structural components which may lead towards fatigue crack initiation and buckling. These failure mechanisms affect tower service life and may result in catastrophic structural failure. Additionally, environmental pollution stemming from corrosion's by-products is possible. As a result, large financial investments are made yearly for both the prevention and recovery of these drawbacks. The corrosion rate of an OWS is dependent on different characteristics of attack which are influenced by access to oxygen and humidity. Structural degradation can occur due to chemical attack, abrasive action of waves, and microorganism attacks. Inspired by technological and scientific advances in recent years, the purpose of this paper is to discuss the current protective coating system technologies used to protect OWS as well as future perspectives.
