Indeximate, a provider of fiber sensing-based cable health monitoring to the offshore wind energy industry, announced that it has demonstrated its cable health monitoring to the offshore wind farm operator RWE. Following their success in RWE’s 2023 innovation competition, over winter 2024-25, Indeximate’s proprietary Scattersphere technology provided continuous health monitoring tracking and analysis of two strings at Arkona offshore wind farm in the Baltic Sea, covering 13 turbines.
Indeximate’s technology leverages existing optical fibers that commonly exist in subsea power cables to collect and automatically interpret distributed acoustic sensing (DAS) data. The monitoring and analysis included key areas of the cable protection system (CPS) between touchdown and aperture, as well as inside the monopile from aperture to hang off where installation of sensors for monitoring has long been a legacy issue for the sector.
Over the six-month period, data was collected on the cables as they were subject to typical winter storm conditions, the effects of gravity and 7-meter-high waves. Dynamic strain measurements from DAS were taken 2,000 times per second at 10m intervals along the cables. Indeximate compressed the raw data in real time using its proprietary Indeximation technology, uploaded to their cloud portal, the Scattersphere, where automated analytics extracted
