Export Systems for Offshore Wind Farms
The potential of HVDC technology on the Polish Baltic Sea
By OWC’s Bartosz Hunek and Piotr Jedrzejewski, 2023
The importance of offshore wind will grow in the coming years, with this technology likely becoming an important part of the future energy mix. From many aspects of offshore wind developments, power evacuation seems to be a critical function that allows generated power to be transferred from the wind farm to the external grid for further distribution. High voltage direct current (HVDC) solutions gain interest for many different reasons. This paper addresses a number of topics related to the subject, with a special focus on the HVDC technology being a potential solution for Polish offshore sites.
Cable Protection Systems and Submarine Cable Failures
Typical causes and remedies
By OWC’s Riccardo Felici and Daniele Caruso, 2022
According to 4Coffshore, around 4,600 subsea cables have now been laid and are serving offshore wind farms globally. Of the 4,600 around 10 incidents are declared annually, resulting in an average cable downtime of 100 days. In the past seven years, 90 subsea cable failures occurred totalling over EUR 350 million in insurance claims.
