Saipem installs second HVDC platform at Dogger Bank offshore wind farm

By NS Energy Staff Writer 18 Apr 2024

Located more than 130km off the North East coast of England, the Dogger Bank project is being developed in three 1.2GW phases, namely Dogger Bank A, B, and C and the project will feature 277 offshore turbines



Saipem has installed the second unmanned high voltage direct current (HVDC) offshore substation platform at the 3.6GW Dogger Bank offshore wind project located in the UK North Sea.

Measuring 75m in length, 45m in width, and 39m in height, the platform employs a four-legged steel jacket foundation structure designed and fabricated by Saipem, installed in water depths of around 28m.

Its installation milestone marks the completion of the second platform out of three planned for deployment at the offshore wind facility, with each being supplied by Aibel.

Located more than 130km off the North East coast of England, the Dogger Bank project is being developed in three 1.2GW phases, namely Dogger Bank A, B, and C. Overall, the project will feature 277 offshore turbines.

The offshore wind project is being executed as a joint venture (JV) between Equinor (40%), SSE Renewables (40%), and Vårgrønn (20%), which in turn is owned by Eni Plenitude and Hitec Vision.

By leveraging its Saipem 7000 vessel, Saipem installed the platform 130km from the UK coastline at Dogger Bank B.

The unmanned HVDC offshore substation platform houses a Hitachi Energy HVDC system developed to transmit power more efficiently than traditional AC systems.

It will receive 1.2GW of AC power produced by the 95 offshore wind turbines of Dogger Bank B. Subsequently, the power will be converted to DC for transmission to an onshore converter station near Beverley in the East Riding of Yorkshire.

The first platform of the Dogger Bank offshore wind farm was deployed at the Dogger Bank A in April 2023. All three platforms will be remotely controlled from shore and will incorporate a streamlined design aimed at reducing weight by 70% per MW compared to previous platform designs.

RWE installs first turbine foundation at 1.4GW Sofia offshore wind farm

By NS Energy Staff Writer 22 May 2024

Expected to be commissioned in 2026, the Sofia offshore wind farm, located on Dogger Bank, 195km from the closest point on the UK’s northeast coast, will produce clean energy sufficient to deliver electricity to the equivalent of 1.2 million households


German utility company RWE has announced installation of the first offshore turbine foundation at the 1.4GW Sofia offshore wind farm in the UK North Sea.

The first monopile foundation installation was carried out by Van Oord’s offshore installation vessel Aeolus. All the 100 foundations at the offshore wind project are anticipated to be in place by spring 2025.

The Sofia offshore wind farm is located on Dogger Bank, 195km from the closest point on the UK’s northeast coast.

Expected to be commissioned in 2026, the facility will produce clean energy sufficient to deliver electricity to the equivalent of 1.2 million households in the UK.

The offshore wind project will have a single offshore converter platform, transmitting the generated electricity 220km to the landfall in Redcar, Teesside.

It will feature 100 Siemens Gamesa SG 14-222 DD offshore wind turbines, each with a capacity of 14MW. The turbine installation at the Sofia offshore wind farm is slated to be completed by the end of 2026.

RWE offshore wind CEO Sven Utermöhlen said: “Installing the first monopile is a highly symbolic moment in the construction of every offshore wind farm. After 14 years of planning and preparation, this is a great achievement for the entire RWE team.

“I’d like to thank everyone involved for their contribution. Building a project of this size and scale is a great opportunity to demonstrate our expertise in delivering offshore wind energy around the globe.”

Installation of the first turbine foundation comes after the deployment of the key subsea cable infrastructure at the offshore wind project. It marks the commencement of offshore construction within the array itself.

RWE selected Van Oord as the preferred supplier for the engineering, procurement, construction, and installation (EPCI) of the monopile foundations and array cables for the Sofia project in 2020.
