The Hornsea Two Offshore Wind Farm, is the second offshore Wind Farm to be proposed for construction within the Hornsea Zone of the North Sea. The Wind Farm will have a total capacity of 1,386MW and following completion in 2022, Hornsea Two will be the largest offshore Wind Farm in the world, capable of supplying clean electricity to over 1.3 million homes across the UK.
The offshore Wind Farm will be located 89km off the coast of Yorkshire, with an export cable coming ashore near the village of North Cotes in Lincolnshire.From there, three underground circuits consisting of 220kV cables, will carry the electricity from the Wind Farm to the National Grid substation at North Killingholme. A total of 360km of 220kV cable will be installed as part of the Hornsea Two project - which is approximately the same distance as Preston to Plymouth.
VolkerInfra has been awarded the contract by Ørsted Wind Power to complete all the civils works associated with the Hornsea Two onshore cable route. The cable route is approximately 39km and will consist of 3x220kV circuits and fibre optics within a 40m construction corridor. Along the cable route there will be 23 joint bays per circuit, with an average section length of approximately 1,600m. There are an estimated 62 Horizontal Directional Drilling (HDD) locations (186 drills),
with a total of approximately 13,500m of HDD. This will include 18 major HDD locations, including two railway crossings.
Peter Cooke, technical development director at VolkerInfra, said: “We are delighted that Ørsted has selected VolkerInfra as their partner of choice to deliver this highly strategic project, which builds on an already successful relationship. We look forward to delivering this exciting project.”
Duncan Clark, programme director for Hornsea One and Two, said: “The UK already leads the world in offshore wind capacity, and we are building the biggest offshore Wind Farm in the world here. We are delighted to award this multi-million-pound contract to VolkerInfra, who we have worked with before on UK projects and look forward to delivering this nationally significant infrastructure project on time and to budget.”
VolkerInfra will be on site in January 2019 to carry out enabling work activities. Following this, main civils works will begin in March 2019, including cable installation, final reinstatement of the joint bays and the entire onshore cable corridor. VolkerInfra is expected to demobilise from site in September 2021.
