Overview of quality control issues related to submarine cables in project cycle of offshore wind power projects in Jiangsu

This paper presents an overview of quality control issues of submarine cables in project cycle of offshore wind power projects in Jiangsu. After analyzing all stages of the overall process of an offshore wind power project cycle, different focus quality control issues related to submarine cable, such as design flaw, reinstallation, harsh offshore construction conditions, damage by external force, application of land cable accessories, excessive ground current and uneven distribution between layers are listed in detail following accident cases. In the end, several practical advices and methods such as the preferences of three-core submarine cable and dry pluggable terminal, improvement of standards of quality control test methods and life cycle management measures are given, in order to improve the quality control of submarine cables.
