Abstract

Taiwan is located in the subtropical zone, with high relative humidity and high salinity in the air, and there are marine organisms attached to structures in the sea. This study will analyze the durability of the corrosion structure materials of the underwater foundation of offshore wind turbines based on the local chemical environment and paint materials. The offshore wind turbine underwater infrastructure is placed in the small boat dock area of the National Taiwan Ocean University in Taiwan. nine kinds of coatings certified by NORSOK M501 were used to prepare specimens, and the metal exposure test was carried out by hanging in seawater. The hanging positions were respectively in the atmospheric zone, splash zone and submerged zone to complete the analysis of the effect of the water environment and attached marine organisms on the corrosion of the coatings.  The results show that the growth stage of the oyster shells attached to the steel pile will be more mature. The BEASY simulation software was used to analyze the corrosion voltage, and the results of the simulated cathodic corrosion protection of steel piles were consistent with the in-situ measurement results, so the detection standard is reliable.
