Proserv is to supply its holistic cable monitoring system (CMS), ECG, to Norwegian international energy company Equinor’s
Hywind Scotland, which in 2017 became the world’s first commercial floating offshore wind farm, located off the coast of Peterhead, Aberdeenshire in north-east Scotland.

Proserv is to deliver its CMS to analyse the condition and integrity of export and inter-array cables across the wind farm utilising the fibre optic cores within the cables. The demonstration, focused on ECG’s data analytics abilities, is scheduled to extend until April 2024 with installation and commissioning set to take place in Q3 of this year.

The technology has been initiated and driven by Proserv, with vital support from its consortium partners Synaptec, a power system monitoring expert, and BPP Cable Solutions, specialists in subsea power cable engineering and management. The Offshore Renewable Energy Catapult (OREC) has also given its support to the group during the development of the solution.

The CMS employs distributed temperature sensing (DTS), distributed acoustic sensing (DAS) and engages Synaptec’s distributed electromechanical sensors (DES) via its passive electrical and mechanical sensor systems. The hardware will be support by the human-machine interface utilising Proserv’s TIACS software suite.


According to Proserve ECG can monitor the condition and performance of cable terminations, a common cause of fail events.

During ECG’s demonstration on Hywind Scotland, BPP Cable Solutions will provide real-time data processing and predictive analytics modelling.This will be achieved by BPP Cable Solutions applying its experience in processing data generated from DTS and DAS, as well as Synaptec’s DES and cable connection monitoring technologies. Specialist predictive data analysis tools will be combined with known cable power transmission performance physics to monitor cable arrays continuously and autonomously.

Paul Cook, Business Development Director – Renewables at Proserv, commented: “We are most grateful to Equinor for enabling us to supply our ECG cable monitoring solution to the Hywind Scotland wind farm and to display the potential and power of this technology, including its data analytics capabilities. Owners and operators urgently need a cohesive O&M strategy around their cable assets and with its scrutiny of terminations, alongside its unique predictive insights, ECG offers unrivalled visibility of this key part of an offshore wind farm’s infrastructure.

“Equally, as floating wind scales up rapidly, this arrangement on Hywind Scotland represents perfect timing for us to show what ECG can do.”


Davis Larssen, Chief Executive Officer, Proserv Controls, added: “The deployment of ECG to Hywind Scotland marks another important stepping stone towards this disruptive technology becoming the benchmark solution for cable asset management in offshore wind.

“In a few short months we have seen ECG selected to support the operation of the world’s biggest offshore wind farm, due to the strength of its proposition, and now it will be supplied to a well-established floating asset, indicating its flexibility, versatility and relevance to the entire offshore wind sector.”


Earlier this year, it was announced that Proserv had secured a contract for ECG to be implemented on the bottom-fixed Dogger Bank Wind Farm phases A and B to monitor the condition and integrity of the asset’s inter-array cables, representing the technology’s first commercial sale.
