Abstract
To address the corrosion protection issue of offshore photovoltaic steel pipe piles in the seawater environment,taking the H off-shore photovoltaic project as the research object,this study adopts methods such as full-life cycle cost analysis,electrochemical principle analysis,and on-site tests to compare the applicability and economy of two cathodic protection technologies:sacrificial anode and im-pressed current.By constructing a cost model,combined with construction technology and environmental impact assessment,the differ-ences between the two in terms of output current capability,protection life,and operation and maintenance costs are quantitatively ana-lyzed.The results show that the cost of impressed current cathodic protection is lower than that of the sacrificial anode method within the 27-year full life cycle,and it has advantages such as adjustable current,environmental friendliness,short construction period,and re-duced labor costs for operation and maintenance.The research results can provide a quantitative basis for the selection of anti-corrosion technologies for offshore photovoltaic steel pipe piles,and it is recommended that large-scale projects give priority to impressed current cathodic protection technology to improve the reliability and sustainability of infrastructure.关键词
