Scottish Power has contracted marine engineering specialist Van Oord and Great Yarmouth-based Seajacks to transport and install the foundation jackets on the East Anglia-1 offshore wind parc.
The £2.5 billion offshore windfarm located in the southern North Sea, about 30 miles off the Norfolk coast, it will generate 714MW of electricity when completed in 2020, enough to power 500,000 homes per year – enabling Scottish Power to deliver more than 50% of UK content across the life of the project when complete.
The project will be the most cost efficient offshore windfarm ever to confirm construction, and is leading the way to meet the UK Government’s cost reduction targets.
The price of £119 MWh was secured after a competitive auction process run by the Government, and is more than 15% lower than other offshore wind projects in construction elsewhere in the UK.
In comparison, the strike price for the proposed new Hinkley Point-C nuclear power station is £92.50-MWhr.
Jonathan Cole, Managing Director of Offshore Wind Renewables at Scottish Power, said: “East Anglia-1 continues to make excellent progress. We are now starting preparations for the onshore work, as well as ensuring all of the plans are in place for the offshore work.
“The project will be the best value offshore windfarm ever constructed, at the same time as delivering industry-leading levels of UK content.”
The main installation vessel will be Seajacks’ state-of-the-art Scylla, the world’s largest and most advanced working in offshore wind. The contract will support 140 current positions with Seajacks, and allows the company to create up to 75 new jobs.
Seajacks will recruit at least five new local apprentices as part of the contract, which will see the Scylla vessel engaged on the project for at least six months, starting in April 2018. Scylla has 105m legs, and is capable of working in water depths of up to 65m. Deck space is 5000 square metres and it has a load capacity of just under 9000 tonnes.
Standing over 65 metres tall, and weighing more than 845 tonnes, the three-legged steel jacket structures support the turbine towers, nacelle and blades.
