COWI has been awarded a contract by Vattenfall for the oversight of the detailed design phase of the onshore cable installation for the Norfolk Boreas offshore wind farm.
The project is the first phase of Vattenfall’s Norfolk Offshore Wind Zone, located 47 kilometres off Norfolk, on England’s eastern seaboard.
Once operational, the zone will have a capacity of 3.6GW.
COWI will review the plans, devised by UK engineering and construction company, J. Murphy & Sons, to install 60 km of cables that will connect where the Norfolk Boreas development makes landfall at Happisburgh, to the Necton National Grid substation.
The route will also serve the Norfolk Vanguard site to reduce construction times, local disruption and environmental impact.
Crossing a railway line, a National Highways road, and countless local roads and rivers, the project poses several technical challenges which COWI is able to support with, spanning knowledge from working with National Highways and Network Rail, as well as in tunnelling, trenching, hydrology and electrical design.
Rob Anderson, Project Director of Vattenfall’s Norfolk Zone, said: “We’re delighted to have COWI on board providing oversight of the work onshore, and making sure that it’s carried out safely and sustainably.
“This is another step forward for the Norfolk Offshore Wind Zone which is a vital part of the UK’s net zero future and a boost for domestic supply chain and new, green collar jobs.”
The announcement adds Norfolk Boreas offshore wind farm to COWI’s green energy infrastructure portfolio in the UK and Ireland where the company is working on a range of projects including the development of pumped storage schemes, wind and green hydrogen projects.
