Tech Blog From Terabytes to Insights: Why a Great GUI is Key for Subsea Cable Health Monitoring The environments in which undersea power cables operate are highly dynamic. To protect these critical assets from the harsh realities of the seabed, the offshore renewables industry is increasingly turning to Distributed Acoustic Sensing (DAS). Tech Blog Closing the Data Gap on Depth of Burial Cable Burial Risk assessment / Depth of Burial is the standard approach for cable health awareness - but it is expensive, time consuming and has massive temporal gaps. Indeximate fixes this with new Automated Depth of Burial now incorporated in Scattersphere for Subsea Power Cable - online monitoring for cable health. Tech Blog The Tidal Cycle: How Indeximate’s Distributed Acoustic Sensing Helped MeyGen Identify And Mitigate Risks To Their Cables Energy from the tides is a predictable and plentiful resource. Extracting it from the sea, though, presents engineering challenges as infrastructure must withstand some of the harshest marine environments on the planet. In this blog, we explore how Indeximate's continuous monitoring of the MeyGen export cables have helped their O&M team overcome some of these challenges. Tech Blog Is Skipping Secretly Destroying Your Cables? The environments in which undersea cables operate are highly dynamic. Strong currents, tidal flows, and seabed interaction can introduce a variety of mechanical stresses that affect cable health over time. Tech Blog Measuring Ocean Waves Using The Cables Beneath Them Ocean waves are a constant and defining feature of the marine environment. Accurately measuring their height, period, and direction is essential for a wide range of applications, from environmental modelling and coastal forecasting to offshore energy operations and marine safety. Tech Blog Real Time Structural Health Monitoring of Offshore Wind Turbines Here at Indeximate, we listen to what your cables tell us. We ‘listen’ using Distributed Acoustic Sensing (DAS) which returns a rich data stream of strain measurements at distinct intervals along the cable, several thousand times per second. News Indeximate enhances monitoring of SSEN’s critical Orkney Subsea Power Cables, Boosting Network Resilience. Indeximate has worked with SSEN to further improve the monitoring of its subsea power cables in Orkney into a sustainable, low-bandwidth solution for one of the UK’s harshest marine environments. Tech Blog From Reaction to Prediction: Measuring Strain and Fatigue on Subsea Cables Sudden and catastrophic failure in subsea power cables is most frequently the consequence of a lack of consistent and comprehensive data on mechanical endurance. Measurement of the long-term mechanical fatigue of subsea power cables remains one of the most significant blind spots in offshore asset management. While fatigue is recognised as a leading cause of cable failure, the actual fatigue accumulated by these complex, multi-layered structures is often not well understood during service. Article Beyond The Edge: Real-Time Vessel Detection from Distributed Acoustic Sensing Data Using Machine Learning vs Classical Methods Vessel activity is one of the biggest threats to subsea cable infrastructure. Traditionally, both unauthorised trawling and unintentional anchor strikes from day-to-day shipping activity have led to damage or even severing of subsea cables: both telecommunications and power. Such risks are frustrating to the industry due to their avoidability if best practices were followed by all stakeholders; however, risks are not confined to accidental damage caused by careless activities. News Educational Breakfast Session hosted by Global Underwater Hub We're kicking off 2026 in style with an educational breakfast session hosted by Global Underwater Hub in their Newcastle office with a deep dive into fibre optic sensing - covering all the individual hardware approaches, what the hardware lets you achieve technically and economically, and then in key detail lifting the lid on the service operations that exploit those rich datastreams to really drive cable health and longevity. Thanks to Ricci Boston and Chris Jones for making the event a reality. News Indeximate receives DNV statement of feasibility for Scattersphere cable health monitoring technology Independent assessment confirms technical feasibility of Scattersphere’s fibre-optic subsea power cable monitoring solution, marking key milestone in the DNV Technology Qualification process. Tech Blog Cable Electrical Response and Integrity Risk Metric Subsea power cables don’t just carry electricity, they generate powerful electromagnetic signals that reveal how their internal structure changes over time. In our latest blog, we explore how these 50/60 Hz signals can be detected using Distributed Acoustic Sensing (DAS). Once interpreted, these signals offer unprecedented insight into cable armour integrity and the overall cable health. Tech Blog Exposing Subsea Cable Risks: Identifying unburied cables using Distributed Acoustic Sensing Cable burial is the first line of defence in offshore wind, protecting export cables from anchors, trawls, tidal forces, and long-term environmental wear. But burial isn’t permanent. Seabed mobility, storms, and even installation techniques can shift material over time, leaving critical sections exposed without anyone knowing. Our latest blog explores how operators can finally gain continuous visibility of burial and exposure conditions News Indeximate Joins €4M Horizon Europe FOREST Project to Advance Ocean Energy Reliability The FOREST Project is transforming ocean energy infrastructure through smarter, data-driven subsea monitoring led by Indeximate’s Scattersphere® technology.
