摘要
[目的]文章旨在研究海上风电场钢结构腐蚀环境、现象和机理,剖析原因,提出海上风电场钢结构防腐的策略,确保海上风电场钢结构全生命周期的安全运行。[方法]以并网发电海上风电场为研究对象,根据不同基础形式、结构件、材料和部位在特定海洋环境中已发生的腐蚀现象进行分析。[结果]结果表明,在特定海洋环境下,不同基础形式、结构件和部位的腐蚀形式与速度存在差异;电化学腐蚀是主要的腐蚀形式,内应力和外力作用是加速钢结构腐蚀的潜在因素;制造质量控制及防护措施实施过程对于钢结构的腐蚀速度具有直接影响。[结论]综上所述,必须识别针对海上风电场钢结构制造特性、材料特性和环境特性而产生的各种潜在风险,并采取相应精细化防护措施消除隐因,同时对于某些关键部位需提高防护等级。
[Introduction]Strategies for preventing corrosion in steel structures at offshore wind farms,derived from a comprehensive study on the environmental conditions,symptoms,and mechanisms of corrosion in such structures,as well as an analysis on various causes were proposed,aiming to ensure safe operation throughout their lifecycle.[Method]The study focused on the grid-connected offshore wind farms and investigated corrosion observed in specific marine environmental conditions for different foundation types,structural components,materials,and parts.[Result]The results show that corrosion appears in various forms and progresses at varying rates among different foundation types,structural components,and parts in specific marine environmental conditions.Electrochemical corrosion is identified as the main form of corrosion,while internal and external stresses act as potential accelerators of corrosion in steel structures.Manufacturing quality control and the implementation of protective measures directly affect the rate of corrosion development.[Conclusion]In summary,it is crucial to identify various potential risks related to manufacturing characteristics,material properties,and environmental conditions of steel structures at offshore wind farms and take appropriate refined protection measures to eliminate underlying causes.In addition,protection levels should be increased for certain critical parts.
