Onshore

Construction and installation on land

Onshore construction began in January 2020 when our contractors, Jones Bros, broke ground near the village of Ulrome in the East Ridings of Yorkshire.

This marked the start of the installation of the c.30km of onshore cable from Ulrome to the Creyke Beck substation to service the Dogger Bank A and B projects.

Work is expected to take around two years to complete.

Onshore cable installation

The electricity generated by the Dogger Bank A and B wind turbines will come ashore via subsea export cables to the north of Ulrome.

The main work will see our contractors:

  • Install access points along the cable route corridor
  • Mark out the onshore cable route and install fencing to provide a safe working environment
  • Create construction compounds along the route (temporary bases for workers and equipment)
  • Excavate cable trenches, install ducting, lay marking tape and boards and backfill/reinstate
  • Install the export cable in the pre-installed ducting from landfall to the converter stations and from the converter stations to the main grid substation

Where required, our contractors will utilise horizontal directional drilling techniques to bypass obstacles including road, rail and river with the minimum of disruption.

Landfall

Our contractors will install ducting (pipes) from onshore out to a point around 500m offshore. They will utilise horizontal directional drilling equipment to install the ducting, passing under cliffs and beaches thereby causing as little disruption as possible.

At a later date, the offshore export cable will be pulled ashore via the ducting and connected to the onshore export cables for the remainder of the route to the converter substations.

At their highest point above sea level, Dogger Bank Wind Farm's turbines are more than two and a half times as tall as Big Ben

Converter stations

Our contractors will construct two converter stations which will take the electricity generated by the wind turbines and convert it from HVDC to HVAC current before the power passes through the adjacent main substation and on to the National Grid.

Operations and maintenance base

In May 2020, we announced that the Port of Tyne would become home to our long term operational base.

The base will contain the infrastructure required to operate the wind farms, including office, training and welfare space.

Equinor will lead on the construction of the multi-million £ base which is expected to generate over 200 direct jobs in the region as well as opportunities for companies at all levels of the supply chain.
