RES secures O&M contract at Walney 1

by RES | May 03, 2022 | Reading time: 2 min

RES, the world’s leading renewable energy developer, has been awarded a contract to provide Operations and Maintenance (O&M) services for offshore transmission (OFTO) assets at Walney 1 Offshore Wind Farm. The commitment to a new contract by Blue Transmission Walney 1 Ltd, following a competitive tendering process, means RES will provide scheduled and unscheduled maintenance of equipment, site management, logistics and control centre services.


RES has been involved in the offshore wind sector since its beginnings in the 1990’s and already provides similar services for Blue Transmission Walney 2 Ltd. As part of the new contract RES will continue to deliver all HV services for Walney 1 OFTO, including 24/7/365 monitoring by RES’ Control Centre.

Robert Fradley, RES Head of Offshore Wind, said: “For the past five years we’ve been providing OFTO services for Blue Transmissions Walney 1 & 2. In that time, we’ve worked closely with our client to deliver a high-quality service that focusses on availability which helps our client maximise the value of their asset. This contract renewal is validation of this approach.”


Gary Thornton, Director, at Blue Transmission, said: “RES was selected due to their expertise in the offshore wind industry, including their knowledge of engineering, technical and operational matters. RES performed well delivering services for Walney 1 and 2 OFTO and we look forward to continuing this partnership.”


Walney 1 Offshore Wind Farm is located in the Irish Sea, off the Cumbrian coast, with the offshore substation platform located 15km from the coast of Walney Island and 18km from Barrow-in-Furness. The offshore substation is connected to the shore by a 45km undersea cable, which comes ashore near Heysham. The onshore cables, which are about 3km long, connect to the onshore substation at Heysham.


RES works to maximise the value of assets, and its offshore O&M services includes data management, marine coordination and weather forecasting, subsea inspections and more. RES now delivers offshore O&M services to six OFTO’s, comprising eight substations.
