摘要: 与常规浅水相比,深水环境温度低(低于7℃),压力大,溶解氧含量、盐度、流速等也与浅水环境不同,同时深水水下生产设施结构形式复杂,维修难度大、费用高,因此深水水下生产设施的防腐设计与浅水设施和常规导管架相比也有一定的区别。主要依据国际主流防腐设计标准规范及已发表的文献,结合水下生产设施的主要特点,对深水水下防腐设计要点和关键参数进行总结和阐述,可为深水环境下的腐蚀防护设计提供参考。

Abstract: In comparison with the shallow water environment, the temperature of deep water is much lower, and the dissolved oxygen content, salinity, flow velocity, etc., are rather different. The subsea production facilities are much more complex due to the hinge/locking mechanism, actuator, guide mechanism, piping and valve, etc. Meanwhile, they are difficult to maintain and expensive. The corrosion control design of deepwater subsea production facilities is different from those of shallow water facilities and jackets. We summarize the main design factors and parameters of deepwater corrosion control based on international standards, literatures and subsea production facility characteristics. The results can be used as a reference for deepwater corrosion control design.
