10th October 2023 in Construction, Press releases, Project news

  • UK Prime Minister Rishi Sunak hails Dogger Bank’s role in bolstering energy security, creating jobs, lowering costs, and achieving Net Zero.
  • First power achieved at UK’s Dogger Bank as the first of 277 turbines installed 130km from UK coast.
  • Dogger Bank is now connected via HVDC technology to Britain’s national grid and providing renewable power to homes and businesses. 
  • Each rotation of the first turbine’s 107m long Haliade-X blades can produce enough clean energy to power an average home for two days. 
  • When complete Dogger Bank will deliver clean energy to six million homes annually.* 

The world’s largest offshore wind farm under construction, Dogger Bank, has started producing electricity for the first time for British homes and businesses, marking a major milestone in the development of the offshore wind industry and the transition to a cleaner, more secure energy system.

UK Prime Minister Rishi Sunak has hailed this landmark moment, saying Dogger Bank will bolster energy security, create jobs, lower electricity bills and keep us on track for Net Zero.

The 3.6GW Dogger Bank Wind Farm is being constructed in UK waters 70 nautical miles (130km) off the coast of Yorkshire and in three 1.2GW phases known as Dogger Bank A, B and C. Power from the project’s first offshore wind turbine at Dogger Bank A is now being transmitted to the UK’s national grid via Dogger Bank’s high-voltage direct current (HVDC) transmission system, marking the first-time use of HVDC technology on a UK wind farm.

First power followed the installation of the first of GE Vernova’s ground-breaking Haliade-X 13MW turbines, one of the largest and most powerful globally, at the Dogger Bank site. This is the first time Haliade-X units have been energised offshore anywhere in the world.

Each rotation of the 107m long blades on Dogger Bank’s first operational turbine can produce enough clean energy to power an average British home for two days.

When fully complete, Dogger Bank’s world-record-beating 3.6GW capacity will comprise 277 giant offshore turbines capable of producing enough clean energy to power the equivalent of six million homes annually and deliver yearly CO2 savings equivalent to removing 1.5 million cars from the road*.

UK Prime Minister Rishi Sunak said:

“Offshore wind is critical to generating renewable, efficient energy that can power British homes from British seas.

“I’m proud that this country is already a world leader in reaching Net Zero by 2050, and by doubling down on the new green industries of the future, we’ll get there in a way that’s both pragmatic and ambitious.

“That’s why it’s fantastic to see the world’s largest wind farm, Dogger Bank, generating power for the first time today from UK waters, which will not only bolster our energy security, but create jobs, lower electricity bills and keep us on track for Net Zero.” 

Dogger Bank is being developed and built by the UK’s SSE Renewables in a joint venture with Norway’s Equinor and Vårgrønn (a joint venture of Eni Plenitude and HitecVision). SSE Renewables is lead operator for the development and construction of Dogger Bank Wind Farm. Equinor will be lead operator of the wind farm on completion for its expected operational life of around 35 years. Vårgrønn brings specialist offshore wind expertise to the project.

Alistair Phillips-Davies, Chief Executive of SSE, said:

“There’s been lots of talk about the need to build homegrown energy supplies, but we are taking action on a massive scale. Dogger Bank will provide a significant boost to UK energy security, affordability and leadership in tackling climate change. This is exactly how we should be responding to the energy crisis.

“But it is also a landmark moment for the global offshore wind industry, with Dogger Bank demonstrating just what can be achieved when policymakers, investors, industry, and communities work together to achieve something truly remarkable.

“The innovations this pioneering project has developed will also mean future developments can be built faster and more efficiently, accelerating the clean energy transition. Now, of course, the challenge is to accelerate the next wave of these projects and we look forward to working with governments to bring these forward as soon as possible.”

Anders Opedal, CEO of Equinor, said:

“Set against the broader energy context, Dogger Bank, the world’s largest offshore wind farm demonstrates the best of what the offshore wind industry can offer, with innovative technologies, long-term jobs and economic growth and security of electricity supply at a major scale.

“A renewable mega-project like Dogger Bank constitutes an industrial wind hub in the heart of the North Sea, playing a major role in the UK’s ambitions for offshore wind and supporting its net zero ambitions.

“First power from Dogger Bank, is a testament to the collaboration between the authorities, the project partners, suppliers and our host communities to realise this project.”

Olav Hetland, CEO of Vårgrønn, said:

“Dogger Bank’s first power milestone demonstrates that offshore wind is ready to power Europe’s energy transition.

“While today we celebrate Dogger Bank providing its first power, the offshore wind farm is delivering much more than renewable energy. The project has contributed to building industry and creating local jobs and will continue to do so over several decades. Maximising these positive local ripple effects of offshore wind projects is essential to maintaining strong support for offshore wind and the energy transition.

“Looking ahead, we expect the Northeast of England to hold a central place in Europe’s offshore wind future.”

At 260 metres tall, the gigantic turbines at Dogger Bank are almost twice the size of the London Eye and the same height as New York’s iconic Rockefeller Centre. The first power milestone marks the first of what will eventually be 277 turbines powered-up across the project. Each of these turbines will be progressively commissioned between now and full commercial operation in 2026. When complete, Dogger Bank will be the world’s largest offshore wind farm, more than two and a half times the size of the largest offshore wind farm currently in operation^.

Dogger Bank sits 70 nautical miles (130km) off the coast of Yorkshire and will occupy an area almost as large as Greater London and nearly twice the size of New York City.

World-firsts in supply chain delivery

The Dogger Bank project has delivered several world-firsts in supply chain delivery that will significantly accelerate the speed at which future offshore projects can be developed. The precision offshore installation of GE Vernova’s new 13MW Haliade-X turbine technology at Dogger Bank A was completed by expert technicians and engineers working off Jan De Nul Group‘s newest jack-up installation vessel, Voltaire. With a lifting capacity of 3,200 tonnes, the Voltaire is the largest offshore jack-up installation vessel of her kind in the world and the first ultra-low emissions ship of its kind.

Dogger Bank also marks the first use of HVDC transmission technology to connect a British wind farm to National Grid’s UK energy network. This includes the installation of the world’s first unmanned offshore HVDC substation platform at the site, as well as first use of Hitachi Energy’s HVDC Light® transmission system which was successfully executed in record time of 38 months with the highest safety and quality standards.

GE Vernova Offshore Wind CEO Jan Kjaersgaard said:

“We are delighted to have energised the first Haliade-X turbine at sea as part of the Dogger Bank Wind Farm, and we want to congratulate our customers and thank all of our partners on achieving this important milestone.  At GE Vernova we are committed to electrifying the world while simultaneously working to decarbonize it.  We are honored to have been able to provide the first of a next generation of 13MW+ turbines for this historic project, reinforcing the critical role of technology innovation in meeting the challenges of climate change.” 

Jan Van Impe, Manager Jan De Nul Offshore Renewables at Jan De Nul Group, added:

“Our Voltaire has proven today that the scale and characteristics of the offshore Dogger Bank turbines offer the perfect challenge for this next generation state-of-the art jack-up installation vessel. We are excited to have installed the very first offshore GE Haliade-X turbine on the Dogger Bank Wind Farm in a sustainable and efficient way, and we are looking forward to continuing this mission with industry leaders SSE Renewables, Equinor and Vårgrønn to further construct the energy transition for the UK energy market.”

Claudio Facchin, Chief Executive Officer, Hitachi Energy, said:

“The urgent energy transition requires strong collaboration, new business models, and global standards. We are proud to be the technology partner for the Dogger Bank Wind Farm project, with HVDC being the force multiplier for the clean energy transition, increasing access to an energy system that is more sustainable, flexible and secure. Today is a significant milestone in securing the UK’s future energy needs, made possible by foresighted partners such as SSE, Equinor and Vårgrønn, that have made the UK a leader in the transition to clean power.”

John Twomey, director of customer connections at National Grid, said:

“It’s a momentous engineering achievement and landmark moment to see Dogger Bank exporting its first power onto the grid. When operational as the world’s biggest wind farm, its turbines will play a key role supplying Britain with green, homegrown energy. We’re proud to have played our part reinforcing our Creyke Beck substation in readiness to safely connect that clean power to our network, and on to homes and businesses around the country.”

Creating local jobs

More than 2,000 UK jobs have been created or supported in relation to the construction and operation activities of Dogger Bank. Many of these are based in the north of England, where the project’s supply chain is creating long-term opportunities for people just starting out in their careers, as well as more experienced workers transitioning from other industries to renewable energy.

RenewableUK’s Chief Executive Dan McGrail said: 

“The sheer scale of Dogger Bank shows that offshore wind is taking centre stage in Britain’s clean energy system as we move away from expensive imported fossil fuels to secure cheap homegrown power.

“This massive innovative clean energy project is a significant step forward for the UK’s world-leading offshore wind industry, creating thousands of jobs and attracting billions in private investment.

“Coastal communities in the north of England and beyond are benefitting from the new industrial opportunities which offshore wind is providing. This shows that the Government is right to press ahead with policies to increase our energy security by ensuring that vital new clean energy projects can be built faster”.

World’s first unmanned HVDC offshore platform installed at world’s largest offshore wind farm

20th April 2023 in Construction, Project news

  • Dogger Bank Wind Farm will be first UK High Voltage Direct Current (HVDC) connected offshore wind farm
  • 70% reduction in topside weight per MW for offshore platforms

Construction of what will be the world’s largest offshore wind farm, Dogger Bank, has reached another milestone with the installation of the world’s first unmanned High Voltage Direct Current (HVDC) offshore substation.

The substation is the first of three platforms, supplied by Aibel, to be installed at Dogger Bank, which is being constructed in three 1.2GW phases known as A, B and C.

The Dogger Bank A platform measures 65 x 36 metres across and 39 metres high and sits on a four-legged steel jacket foundation structure which is fixed to the seabed, at a water depth of around 28m.

Approximately 146km from the nearest point of land at Flamborough Head, near Bridlington in East Riding of Yorkshire, the platform installation was delivered by principal contractor Sapiem.

The innovative offshore platform has a lean design and is the first unmanned HVDC platform which will be operated from shore and accessed only by a Service Operations Vessel. The platform will receive 1.2GW of AC power from Dogger Bank A’s 95 offshore wind turbines and convert it to DC, which will then be sent ashore to an onshore convertor station near Beverley in East Riding of Yorkshire.

Fitted with Hitachi Energy’s latest generation HVDC converter technology, Dogger Bank will be the first offshore wind project in the UK to use this technology to transmit the electricity produced back to shore, ensuring that the electricity is transmitted efficiently over long distances while minimising losses.

Olly Cass, Project Director for Dogger Bank Wind Farm, said:

“The safe and successful installation of the offshore platform marks a major milestone in the Dogger Bank project. As the UK’s first HVDC platform for an offshore windfarm it is also a major milestone for the UK industry more widely.

“The platform will be controlled from shore and by removing the need for personnel to stay on the platform meant it has been possible to eliminate elements such as the living quarters, helideck and sewage systems, resulting in a 70% reduction in weight (per megawatt) of the topside compared to previous platforms installed, and cost savings of hundreds of millions of pounds.

“Teams continue to make good progress with the installation of turbine foundations and later in Q2 specialist cable installation and support vessels will start to install the inter-array network of cables that will connect the turbines to the offshore platform to enable transmission of first power in the summer.”

Dogger Bank Wind Farm, a joint venture between SSE Renewables, Equinor, and Vårgrønn, is set to be the world’s largest offshore wind farm consisting of 277 wind turbines. The wind farm will be capable of of generating 3.6GW of renewable energy which is enough clean and sustainable electricity to power more than 6 million homes.

Ducting work for Dogger Bank and Sofia Wind Farm projects nearing completion on Teesside

29th March 2023 in Construction, Project news

More than 80% of the ducts that will house the cables transmitting renewable energy from two offshore wind projects to the national electricity network has been installed in Teesside.

Working in cooperation, Sofia Offshore Wind Farm and Dogger Bank C, the third phase of Dogger Bank Wind Farm share onshore cable corridors and to minimise local disruption, have joined forces to have their cable ducts installed by the same contractor at the same time.

The projects are both located on Dogger Bank, more than 195 kilometres from the north-east coast of England, with their export cables coming ashore on 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 Vårgrønn. Although they are owned by different companies, the developers realised early that it made sense to work jointly on their shared cable corridor, with civil engineering works being carried out by J Murphy & Sons (JMS). Sofia is leading the works on behalf of both projects.

More than 80% of the ducts that will house the cables transmitting renewable energy via the national electricity network on Teesside from two offshore wind farm projects are now in the ground and trenches backfilled.  Work is underway on one key section of the route that requires the ducts to be installed using tunnelling rather than by trenching or horizontal directional drilling. Shafts have been established and a micro-tunnel boring machine is now working 24/7 to create four tunnels under the railway line at Black’s Bridge/Redcar Road.

The projects’ high voltage direct current (HVDC) cables will be pulled through the ducts, 7 kilometres to two new converter stations now under construction on the Wilton complex to the north-east of Lazenby. The first of the cables will arrive in the summer to be pulled through the ducts.

Each project will have a further 2 km of high voltage alternating current (HVAC) cables to transmit the converted power to the existing National Grid substation at Lackenby, where it will enter the national electricity network for distribution to homes and businesses.

Dogger Bank Wind Farm onshore package manager Stephen Reynolds, said:

“We really appreciate the ongoing patience of the local community as our joint contractor continues to install this critical infrastructure in readiness for first power from Dogger Bank C in 2025.

“Some of our ongoing works near the beach landfall requires extended working hours during evenings and weekends as we progress the projects, but our contractors are committed to ensuring mitigation is in place to minimise disruption wherever possible.”

Elsewhere on the two projects’ work is ongoing at the landfall site near Marske-by-the-Sea, with horizontal directional drilling due to take place between March and May in preparation for receiving the first cables this summer.

There may be some evening, overnight and Sunday working required at this location, but contractors are committed to ensuring noise and disturbance is minimal.

And at the site adjacent to the Wilton complex, near Lazenby village, work continues on the construction of the projects’ onshore converter stations as the valve halls, control rooms and storage buildings start to take shape. Some Sunday working will be required for the remainder of the year to carry out elements of groundwork and electrical installation, with measures also being taken there to minimise disruption.
