E. ROCHAT et al. Using Brillouin distributed sensing to reduce installation risk and optimize cable operation of subsea power cable
Omnisens has been awarded a contract by Nexans Cables for the supply of a permanent monitoring system for the export power cable network of the Beatrice Offshore Windfarm in the Outer Moray . This continues a long established collaboration where Omnisens fibre optic based temperature monitoring systems are being used to monitor the health of critical Power Supply cable networks for the UK’s power generation capacity.
Beatrice Offshore wind farm will be one of the world’s largest offshore wind farms when operational in 2019 producing 588 MW. The export cable system is over 90kms long, and each meter of the Power Cables will be monitored continuously to ensure the cable temperature remains within the safe operating limits.
Omnisens has been selected by DONG Energy to provide Power Cable temperature monitoring systems for the entire export power cable network of Hornsea Project 1 offshore wind farm. This will be one of several DONG Energy projects already awarded to and completed by Omnisens. At 1.2GW Hornsea Project 1 will be the world’s largest offshore wind farm, when it comes into operation in 2022.
Every meter of the export power cable network will be continuously monitored with a temperature accuracy within 2 degrees C to ensure the temperature is controlled within safe operating limits. Each cable circuit is approximately 180 – 190kms long, and the specifications represent one of the most challenging the industry has so far seen.
