The development of HVDC transmission systems has become increasingly important in recent years, as these systems can transmit large amounts of power over long distances with minor losses. Underground power cables are one of the technologies used in more and more applications. An obvious use of HVDC cables is for submarine applications. Submarine cables are used to connect offshore installations, such as production platforms in the oil & gas sector or substation platforms in the offshore wind sector, to the mainland grids.
Although the cables account for just a small percentage of the total investment in the required equipment, failure would result in high costs relating to lost production and repair. Given the potential costs, investors want to mitigate risks. Despite the existence of various standards, guidelines and recommendations, there is no overall quality standard for the cabling process from start to finish. The design, manufacturing, testing and commissioning of a submarine cable thus need to be carefully implemented, including quality assurance and quality control in each phase.
This five day course will address and highlight the entire HVDC submarine cable life cycle, providing participants with a holistic view and sound understanding of HVDC submarine power cables and their accessories. It will also include an overview of the risks during the various phases of an HVDC project.
