One third of onshore high voltage cables and three quarters of ducts installed for first two phases of Dogger Bank Wind Farm

3rd December 2021 in Construction, Press releases, Project news, Supply Chain

Three quarters of the ducts and a third of the on-shore high voltage cables that will connect the first phases of the world’s largest offshore wind farm to the UK’s National Grid have now been installed.

Jones Bros Civil Engineering UK is delivering the land-based infrastructure for the first two phases of Dogger Bank Wind Farm, which will connect to the National Grid near Beverley, East Riding. There are also a number of UK-based specialists supporting the Jones Bros team with the cable installation work.

The North Wales-headquartered company is responsible for installing 80 miles of underground cabling in underground ducts on land in East Riding of Yorkshire from the landfall site at Ulrome, to the onshore convertor station near Beverley.

With wetter weather now closing in, much of the site is entering a winter shutdown in order to preserve the quality of the soil. However, some drilling work will continue into the new year under the A1079 north of Woodmansey, and at the Creyke Beck Substation, with the tier one contractor planning to complete this by Spring 2022.

Onshore works manager for Dogger Bank Wind Farm, Oliver Flattery, said:

“Great progress has been made over the last few years to prepare the land-based infrastructure for the first two phases of the world’s largest offshore wind farm.

“We remain committed to operating safely, sustainably and respectfully as we continue our drilling work in East Riding of Yorkshire, and as duct and cable installation work picks up again in the Spring.”

James Lockwood, project manager for Jones Bros, said:

“We have made excellent progress while the weather has been with us, and as such have installed a significant amount of cable.

“The cable itself runs across two routes: a DC route which goes from the connection point with offshore cables to the converter station, and a shorter AC route, which then runs from the converter station to National Grid infrastructure.

“Additionally, we have been able to start some works restoring parts of the site, a process which includes sowing a mix of specially selected cover crops that will help maintain the nutrient levels in the soil in preparation of the final reinstatements work due to carried out next year.

“Once better weather returns in the spring, we’ll be back underway with high voltage duct and cable installation, working towards a final site handover in June 2023.”

The team has also constructed 28 of the project’s 74 joint bays, which will form part of the infrastructure for the connection between offshore power cables and the mains grid.

Dogger Bank Wind Farm, which is being built more than 130km off the Yorkshire coast in the North Sea, is currently being developed in three 1.2GW phases: Dogger Bank A, B and C.

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each. The deal is expected to complete in Q1 2022, subject to  regulatory approvals.

DOGGER BANK C REACHES FINANCIAL CLOSE

2nd December 2021 in Construction, Press releases, Project news, Uncategorised

Joint venture partners SSE Renewables and Equinor have reached financial close on Dogger Bank Wind Farm C, the third phase of what will be the world’s largest offshore wind farm when complete in March 2026.

SSE Renewables and Equinor are already constructing the first two phases of the 3.6GW Dogger Bank Wind Farm with Eni, joint venture partner on phases A and B of the world-leading offshore wind project to be installed off the north east coast of England. Now, with financial close being reached on the project’s third phase, Dogger Bank Wind Farm has passed the last important milestone ahead of its construction delivery programme.

Total investment in Dogger Bank Wind Farm will be around £9 billion, of which around £3 billion is for phase C including offshore transmission capex in the range of £900-1000m.

Dogger Bank C has a capacity of 1,200MW and will generate around 6TWh. In total, Dogger Bank will produce enough clean, renewable electricity to supply 5% of the UK’s demand, equivalent to powering six million UK homes.

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). On 2 November 2021 SSE and Equinor announced the sell down of a combined 20% share in Dogger Bank C to Eni (10% each) for a total consideration of £140m. The transaction is expected to close in Q1 2022, subject to regulatory and lenders approvals and customary purchase price adjustments. Eni will enter the asset effective from completion of the sell down transaction. Once the transaction is complete, the new overall shareholding in Dogger Bank C will be SSE Renewables (40%), Equinor (40%) and Eni (20%). Extended partner alignment will enable further synergies across, both in the construction and operations phase of the Dogger Bank wind farm.

Dogger Bank Wind Farm is pioneering new technology and breaking world records in its delivery including green financing records. Financial close on Dogger Bank C has been reached through the financing support of a group of lenders comprising 28 banks and three export credit agencies (ECAs). Taken in aggregate with the financing last year of the A and B phases of the Dogger Bank project, reaching Financial Close on all three phases of Dogger Bank Wind Farm is the largest offshore wind project financing to date globally.

Alistair Phillips-Davies, SSE Chief Executive, said: It is a fantastic achievement to be reaching financial close on the third phase of the world’s largest offshore wind project, just weeks after COP26 concluded in Glasgow and today marks an important early milestone in the delivery of our own Net Zero Acceleration Programme. Our plans will enable delivery of over 25% of UK’s 2030 40GW offshore wind target, whilst also expanding overseas, delivering over 20% of upcoming UK electricity networks investment and deploying the critical flexibility technologies to provide security of supply.

“Construction is well underway on the first two phases of Dogger Bank with work on the third phase already progressing and we look forward to this ramping up in the New Year. As well as providing clean, green power, Dogger Bank is enabling the planned GE blade manufacturing plant in Teesside and a huge number of direct and indirect jobs.

Pål Eitrheim, Equinor EVP of New Energy Solutions, said: Reaching financial close on the third phase of Dogger Bank is a significant milestone as it demonstrates that we are on track with developing what will become the world’s largest offshore wind farm. The extensive interest from lenders underpins the attractiveness of UK offshore wind assets and the confidence in SSE and Equinor as developers. The level of interest achieved reflects the quality of the project and enables strong return on equity. As the wind farm’s future operator, we will leverage our offshore execution capability and continue to deliver value for years to come.”

Dogger Bank C is being project financed with gearing of c.70% for the generation assets. Gearing on the transmission facilities is set at 90% of the forecast OFTO sale proceeds, in line with standard market practice in the sector. Total senior debt facilities is around £2.5 billion plus ancillary facilities of around £435 million.

With the strong interest from lenders, Dogger Bank C was able to secure competitive terms, despite continued impact from the coronavirus pandemic on the macroeconomic environment. The final group of lenders includes experienced lenders, many of which are relationship lenders of both SSE and Equinor. The majority of lenders are the same as for the financing of Dogger Bank A and B, reached in November 2020.  A list of Dogger Bank C lenders, ECA and Advisors is available to download here.

SSE Renewables is leading on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the wind farm on completion for its expected operational life of around 35 years.

Ryder Geotechnical providing local expertise to Dogger Bank

16th November 2021 in Construction, Press releases, Project news, Supply Chain

The world’s largest offshore wind farm is once again benefiting from supply chain expertise in the north-east of England as it continues site preparation work for the installation of turbines in the North Sea.

Working in collaboration with Global Maritime, Newcastle-based Ryder Geotechnical, a Tekmar Group company, delivered a site-specific assessment in preparation for the installation of 190 turbines for the first two phases of Dogger Bank Wind Farm.

The wind farm is being built in three phases; Dogger Bank A, B and C, and when complete will be able to generate around 5% of the UK’s electricity. The project will use the world’s first Ultra-Low emissions jack-up vessel to install turbines 130km out to sea, off the North East coast of England.

Turbines are installed by a jack-up vessel, a ship that extends legs down to the seabed and lifts itself up to provide a stable platform to perform installation from. Ryder’s role in this project was to assess the geological conditions above and below the seabed surface at both sites and provide geotechnical information ahead of the jack-up operations. The geotechnical information is used to advise on the seabed load bearing and other parameters needed for installation.

Steven Metcalfe, lead engineer on the project from Ryder said “We’re delighted to have this opportunity to work on the world’s largest offshore wind farm. The site was particularly complex geologically due to soft clay layers sandwiched between firmer sand layers, but working closely with Global Maritime we were able to fully assess these holistically, and develop solutions for the safest operations.”

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each, in a deal that is expected to complete in Q1 2022 (subject to Dogger Bank C Financial Close and regulatory approvals).

SSE Renewables is leading on the construction of the wind farm and Equinor will operate the wind farm for its expected lifetime of 35 years.

Halfdan Brustad, Vice President for Dogger Bank at Equinor said: “This site-specific assessment carried out by Ryder Geotechnical is essential for us to confirm the turbine fixing requirements ahead of construction and to understand any geotechnical risk to jack-up operations, ensuring safe installation offshore. It’s another great example of UK expertise helping us to deliver the wind farm safely and efficiently as we prepare for offshore installation to commence in 2022.”
