| The work aims to research and develop a kind of anticorrosive coating repair system in splash zone of offshore platform pile leg which can be constructed in the seawater environment, i.e., a three-layer coating structure and its construction method. A material system and construction methods suitable to repair the anticorrosive coating were developed by material research, product production research, property evaluation as well as field application and testing. Hydrophobicity of the hydrophobic sealing oil of the three-layer coating protective structure was 98.4%, while tensile strength of the anticorrosion belt was up to 18.6 MPa and elongation at break was up to 21.6%; tensile strength of the protective sleeve was up to 31.8 MPa, elongation at break was up to 760% and UV-resistant duration was up to 3000 h. The three layer coating protection system could resist the once-in-a-century ice impact in Bohai Gulf. The three-layer coating protective materials developed by our lab turned to be an excellent repairing technology and be capable of protecting offshore platform pile leg and other similar structures in splash zone from corrosion. In addition, the materials met the construction and anti-corrosion requirements of marine environment in addition to the corrosion protection and ice impact resistance requirements of offshore platform pile leg in the splash zone. |
