| Objective To study corrosion state of offshore oil jacket platform and ensure that the jacket is in the cathodic protection state. Methods The data in nearly three years obtained by the corrosion monitoring system were discussed. According to data obtained by the potential current sensor in the different places, corrosion state of each observation point was compared and analyzed. Results As the data research showed, the data collected by the potential current sensor this system was accurate and reliable. All electrode potential at node of jacket was in the range of protection. The output current of the sacrificial anode was stable in the current state. Conclusion The cathodic protection and monitoring system of the platform runs well. All of the measured points are protected and almost completely polarized. This result has an important reference value on the design and construction of offshore oil jacket platform. |
