The 400 MW offshore wind farm transformer platform “Horns Rev 3”, located off the west coast of Denmark, is connected via a single 36 km long, three-phase subsea cable to the shore. From there 3 single-phase 220 kV cables continue for another 45 km to the Endrup substation. The operators were searching for a solution to locate cable faults immediately upon occurrence.
AP Sensing is providing a fully integrated system, monitoring acoustic faults and the thermal profile of the cable system, utilizing a unique combination of Distributed Temperature Sensing (DTS) and DAS (Distributed Acoustic Sensing).
