| 目的 为自升式平台的腐蚀控制提供了一个良好的解决方案。方法 根据自升式平台桩腿结构特点和使用维护要求，设计一种竖直拉伸式的辅助阳极。该阳极系统集成了特种抗拉伸电缆，依靠平台上部的固定点和置于海床上的配重进行拉伸固定。根据平台需要经常移动的特点设计一键自动提升装置。采用计算机数值模拟对系统的安装位置进行优化设计，使该系统达到最佳的保护效果。结果 系统运行1年后，测得桩腿电位范围为-860~-950 mV，水下检测桩腿无明显腐蚀现象。结论 该技术可有效地对自升式平台桩腿进行保护，确保了自升式平台桩腿在设计使用年限中的正常使用。 |

| Objective To provide a good solution for corrosion control of jack-up platforms. Methods A vertical tension type auxiliary anode was designed according to structural characteristics of pile leg and its requirements on use and maintenance. The anode system integrated special anti-stretching cables and was fixed with fixation points on the upper platform and the counter weight on the seabed. And an automatic lifting device was designed to adapt to frequently movement of the platform. The installation site was optimized through computer numerical simulation to achieve the best protective effect. Results After the system was operated for one year, the potential range measured on the pile leg was -860~-950 mV. No apparent corrosion was found in underwater detection of the pile leg. Conclusion This technology provides a good solution for corrosion control of jack-up platform and guarantees normal using of the jack-up platform’s pile leg in design service life. |
