THE problem with Traditional monitoring methodsAre you counting the cost of cable and termination failures on your wind farm?Subsea cable and termination faults amount to one of the biggest hurdles to the successful future growth of offshore wind.These faults are common, but they can take a lot of time to fix. ORE Catapult data shows that they are responsible for 75-80% of the total cost of offshore wind insurance claims. Compounded over the 30 year life of the wind farm, the potential liability could spiral to £25m for inter-array cables and £292m for export cables* - and that’s not including lost power generation. The issue is that traditional monitoring methods, such as ROV inspections or isolated sensors will not help to mitigate these costs, as they are reactive and can only offer an isolated view of an individual fault. Worst still, standard inspections can miss crucial faults on joints and terminations, and any warning signals that a problem has occured comes too late. Cable failures remain the single largest operational cost in offshore wind. Most power cable faults can be traced back to issues with terminations, where jointing and earthing can be vulnerable to degradation over time. Monitoring sheath currents and temperatures in these terminations and screen connections provides earlier and economical failure warnings for every termination on any windfarm in one, retfrofittable online monitoring system.

Scalable cable fault detection throughout a wind farm with ECG™ Holistic Cable Infrastructure Management System Technology
Maximise operations with cable assuranceECG™ advanced sensor technologies delivers real-time data on the condition and integrity of your cable, allowing an operator to see a snapshot of the cable’s health. However, beyond that, the real value of gathering this data is trend analysis over time. At Proserv, we believe in open data, and ECG™ seamless hardware integration provides access to every single point of cable data, present and historic, in your windfarm. But in a time-poor, data-rich operating environment, who has the time to sit down and analyse these huge volumes of data to identify any potential problems?In the past, the only way to deliver cable assurance services would be by using a cable consultancy service. Consultants would package up data from numerous sources, analyse and report back, offering recommendations. This labour-intensive process would take place even if the cable was operating under normal parameters. What’s more, with no real-time visualisation, any anomalies could be out of date by the time the report is delivered. Our services remove the need for lengthy analysis simply to confirm ‘business as usual’. Our cost-effective automated reporting delivers regular cable intelligence in a timely manner, with a detailed summary of any out of normal events and their potential impact on cable and termination health. With Proserv’s cable assurance services, we add value to the data you are already collecting. From this, our cable experts can deliver a human intelligence report that looks at each cable and termination in detail to identify fatigue over time, providing informed recommendations on cable risks and their potential impact on operations, and even offer predictions on cable life. By using data intelligence, our data experts can pick up on potential failures and provide recommendations much faster than the traditional consultancy approach. This powerful mix of AI and human expertise puts the decision-making power back into the hands of the operators, who can make a fully informed maintenance strategy for their cables, maximising operational life. Our cable assurance services are sensor agnostic and can plug into any existing sensor hardware. The algorithm can crunch the numbers from any sensor the operator specifies - be those recommended ny our ECG™ experts, or any other OEM sensor technology, allowing for full flexibility, as well as the ability to retrofit the software onto an existing windfarm.

The world’s first commercial floating offshore wind farmLocated off the coast of Peterhead, Aberdeenshire in north-east Scotland, Hywind Scotland is the world’s first commercial floating offshore wind farm. Since the wind farm began production in October 2017, Equinor has revealed that Hywind Scotland has achieved the highest average capacity factor of all wind farms.Real-time data processing and predictive analytics modellingProserv ECG™ not only employs distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) but engages Synaptec’s unique distributed electromechanical sensors (DES), via its passive electrical and mechanical sensor systems. The hardware will be complemented by Proserv’s innovative HMI design philosophy, utilising Proserv’s TIACS software suite.During ECG’s demonstration on Hywind Scotland, Proserv will deliver advanced real-time data processing and predictive analytics modelling. This will be achieved with vital support from technology partner and specialists in subsea power cable engineering and management, BPP Cable Solutions. The system’s specialist predictive data analysis tools will use known cable power transmission performance physics to monitor cable arrays continuously and autonomously. This will provide assurance of cable health and identify in advance any anomalies and potential longer-term faults that can be dealt with on a proactive basis.This approach represents a major shift from traditional reactive cable performance monitoring, whereby a cable fault or failure identification using stored data only occurs after an event takes place through retrospective root cause analysis.Monitoring the condition and performance of cable terminationsCritically, ECG can monitor the condition, integrity, and performance of cable terminations, an aspect needing development in the offshore wind sector. Cable terminations are well-known for being a serious failure point and so this technology solution will scrutinise this specific key area of an asset, not possible with traditional cable monitoring systems.
