Over the last years many HVDC (High Voltage Direct Current) links have been studied, commissioned and built. Among the constraints, one of the most important is the corrosion risk for surrounding submerged/buried metallic structures. When the coastal area is rich of metallic structures, corrosion risk may be unacceptable, requiring the relocation of the electrode at significant distance offshore. As seafloor at the selected location may be considerably deep, relevant issues about installation and maintenance must be addressed in the design phase. A modular electrode design, able to cope efficiently with all such requirements and minimizing the overall cost has been developed.

Abstract
Over the last years many HVDC (High Voltage Direct Current) links have been studied, commissioned and built. Among the constraints, one of the most important is the corrosion risk for surrounding submerged/buried metallic structures. When the coastal area is rich of metallic structures, corrosion risk may be unacceptable, requiring the relocation of the electrode at significant distance offshore. As seafloor at the selected location may be considerably deep, relevant issues about installation and maintenance must be addressed in the design phase. A modular electrode design, able to cope efficiently with all such requirements and minimizing the overall cost has been developed.File | Dimensione | Formato | |
