J. Murphy & Sons Ltd to Design and Deliver HVDC Export Cable Onshore Civil works for Sofia and Dogger Bank C OWFs
J. Murphy & Sons Ltd is pleased to announce that we have been selected to design and deliver the HVDC Export Cable Onshore Civil works in relation to both the Sofia and Dogger Bank C offshore wind projects.
Sofia Offshore Wind Farm and Dogger Bank C, the third phase of Dogger Bank Wind Farm are both located on Dogger Bank, more than 195 kilometres from the North East coast of England, with their export cables coming to shore in 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 they are owned by different companies, the developers are working jointly at the site of their adjacent converter stations and along the shared onshore cable route.
The projects’ offshore HVDC export cables will connect to onshore cables that will run 7 kilometres to a new converter station – one for each project – now under construction to the North East of Lazenby. Each project will have a further 2 kilometres of HVAC cables to transport power 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 onshore cable ducts which connect the landfall site in Redcar to the HVDC Onshore Converter station. The Group will also work with local colleges and suppliers to recruit local resources and talent.
The main scope of works for Murphy include:
- Detailed engineering and design for the works
- Ecological Management
- Civil infrastructure installation
- Engineering and installation of crossings
The main civils works will commence in March 2022 and run through until the end of 2024. Once operational these two offshore wind projects will generate enough green power to supply all of the North East’s electricity needs every year.
The work builds on Murphy’s proven track record in providing vital cabling to key infrastructure assets, working across traditional power, new nuclear and renewable energy areas. In recent years, the Group has amassed significant experience in the fields of onshore cable civils work and cable installation, working on civils and cable install on projects such as the Triton Knoll, Hornsea Project One and Beatrice wind farms.
