渤海八号平台腐蚀评估

The Corrosion Assessment of Bohai No.8 Offshore Platform

叙述了渤海八号平台的使用环境和采取防腐措施 ;分析了八号平台的腐蚀类型 ;对处于不同部位 (大气区、飞溅区、潮汐区、全浸区和海泥区 )的平台构件进行了腐蚀分析和评估 ;给出了预测腐蚀速率的腐蚀动力学方程式。最后给出了结论和建议。

In order to give a theoretical basis for the application of existing platform and the design of new platform,the corrosion condition of Bohai No.8 offshore platform is reviewed and assessed.The conditions,service environments and the anti corrosion measures of the platform are introduced.The reasons and patterns of corrosion of the platform are analyzed.The corrosion analysis and assessment are carried out for different members and at different positions of the platform.The dynamic equations of corrosion for prediction the corrosion speed are derived.Finally,some conclusions and suggestions are presented.
