| Abstract: |
| The work aims to fill the gap in the construction technology of horizontal new jacket platform and solve the engineering application problem of tensioned ICCP system in horizontal new jacket platform. Based on the first engineering application of tensioned ICCP system in a horizontal new jacket, the onshore installation, jacket transportation and offshore installation of the tensioned ICCP composite cable-electrode system on the jacket were studied, and the installation scheme suitable for the horizontal new jacket tensioned ICCP system was designed. In order to ensure the reliable installation of the horizontal construction jacket tensioned ICCP system, the zipline traction method was used for the design and the self-storage working conditions of the composite cable-electrode system during the offshore installation period were checked, which could ensure the safe and smooth installation of the tensioned ICCP composite cable-electrode system. This set of tensioned ICCP installation scheme not only realizes the first engineering application of tensioned ICCP in horizontal new jacket, but also provides reference for the design and installation of subsequent new jacket tensioned ICCP system. |
