| Abstract: |
| The state-of-the-art in cathodic protection technology for marine infrastructures in deep sea was reviewed. This critical review outlined the research progress in cathodic protection parameters, sacrificial anode materials, and the application of cathodic protection technology in deep sea. Emphasis was put on the influence of environmental factors such as hydrostatic pressure， dissolved oxygen content， temperature and velocity on the cathodic protection potential, the current density criteria and the performance of sacrificial anodes. Temperature and velocity were found to be the two key factors influencing the cathodic protection current density, while the performance of sacrificial anodes was mainly influenced by temperature and the cyclic hydrostatic pressure. Finally， the trend of development of cathodic protection technology for marine infrastructures in deep sea was discussed. |
