| Abstract: |
| 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. |
