摘要

Abstract

As a vital component of clean energy

the long-term reliability of offshore wind power cable systems directly impacts the operational efficiency and economic benefits of entire wind farms. This study systematically analyzes the effects of multiple corrosion mechanisms—including seawater corrosion

chloride ion erosion

and microbial corrosion—on cable performance under complex marine environments. By establishing a corrosion kinetics model for offshore wind power cables

the research reveals quantitative relationships between environmental factors (temperature

salinity

dissolved oxygen) and corrosion rates. The study developed a multi-layer composite anti-corrosion technology system

incorporating key innovations such as modified polymer anticorrosive coatings

optimized cathodic protection system design

and improved sacrificial anode material formulations. A long-term service performance evaluation system was established

utilizing accelerated aging tests

electrochemical impedance spectroscopy (EIS) measurements

and mechanical property assessments to evaluate cable performance degradation over a 25-year design life.Results—demonstrate that the developed composite anti-corrosion technology reduces corrosion rates by over 65%

maintains insulation impedance retention rates above 85%

and preserves mechanical strength retention rates exceeding 90%.
