AP Sensing Monitoring Kriegers Flak Cables

Danish transmission operator Energinet has selected AP Sensing to monitor the cables at the Kriegers Flak offshore wind project.

AP Sensing is monitoring a total of 300km of cable, using 6 Distributed Temperature Sensing (DTS) units with a range of 30-50km for thermal profiling and to detect thermal abnormalities and 9 Distributed Acoustic Sensing (DAS) units with ranges from 25-50 km and 1 channel each for fault location.

The company’s equipment is in use on the Kriegers Flak A and B offshore platforms, as well as on the onshore substations Bjaeverskov and Ishoj.

The monitoring solution also uses the SmartVision asset visualization software, which, as AP Sensing says, provides a real-time graphic overview of all distributed temperature and acoustic information at each of the substations.

This is said to provide at-a-glance information on the condition of the power cable circuits and pre-defined sections for alarming, as well as intelligent data analysis and storage.

AP Sensing’s project engineering team commissioned and tested the systems in the spring.

The Kriegers Flak offshore wind farm will feature 72 Siemens Gamesa 8.4MW turbines installed 15-40km off the Danish coast and scheduled to be fully operational before the end of 2021.
