J Murphy Resumes Sofia, Dogger Bank C HVDC Gig – reNews
J Murphy & Sons has been selected to design and carry out the onshore civil works of the HVDC export cable for the 1400MW Sofia and 1200MW Dogger Bank C offshore wind projects.
Both schemes are located on the Dogger Bank, over 120 miles from the North East coast of England, with their export cables coming ashore at Teesside, between Redcar and Marske-by-the-Sea.
Sofia is 100% owned by RWE and Dogger Bank Wind Farm is a joint venture between SSE Renewables, Equinor and Eni.
Although owned by different companies, the developers work together at the site of their adjacent converter stations and along the route of the shared terrestrial cable.
The projects’ offshore HVDC export cables will be connected to the onshore cables which will run 7 kilometers to a new converter station – one for each project – currently under construction northeast of Lazenby.
Each project will have an additional 2 kilometers of HVAC cables to carry electricity to the existing National Grid substation at Lackenby, where it will enter the National Grid.
Under the terms of this award, Murphy will work to install the terrestrial cable conduits that connect Redcar’s landing site to the HVDC Onshore Converter station.
The company will also work with local colleges and vendors to recruit local resources and talent.
The main scope of work includesdetailed engineering and design of works, eecological managementinstallation of civil infrastructure, and eengineering and installation of bushings
The main civil works will start in March 2022 and will continue until the end of 2024.
Once operational, these two offshore wind projects will generate enough green energy to meet all of the North East’s electricity needs each year.
The contract builds on Murphy’s proven track record working on civil and hardwired installations on projects such as the Triton Knoll, Hornsea Project One and Beatrice wind farms.
Murphy’s Energy Division Managing Director Jon Downs said: “We are delighted to have been named the civil high-voltage cable delivery partner for two of the country’s most important strategic renewable energy projects.
“As Murphy Energy, we are committed to helping our customers accelerate the clean energy transition on our journey to Net Zero and deliver 40 GW by 2030.
“These projects are a key part of this journey and we are thrilled to play such a pivotal role in bringing them to fruition.”
Sofia Project Director Matthew Swanwick added: “Murphy’s appointment marks another significant milestone for the project and the start of civil works for the cable route will mark a visible new phase of onshore construction.
“We will build on RWE’s positive working relationship with Murphy and look forward to our continued cooperation with Dogger Bank C and continued good relations with our stakeholders and the local community.”
Stephen Reynolds, Dogger Bank Windfarm Onshore Work Package Manager for the third phase of the project, said: “We welcome Murphy and look forward to working with them alongside the Sofia Offshore Wind Farm as we develop the onshore infrastructure for these important renewable energy projects.”
