Second HVDC offshore substation installed at Dogger Bank Wind Farm

Wind Energy – Dogger Bank B

Dogger Bank, set to become the world’s largest offshore wind farm, has achieved a significant milestone as the second unmanned High Voltage Direct Current (HVDC) platform has been installed by Saipem.

The substation is the second of three platforms, each supplied by Aibel, to be installed at Dogger Bank offshore wind farm, which is being constructed in three phases known as A, B, and C, each with a capacity of 1.2GW.

The platform was installed 130km from the UK coastline at Dogger Bank B by Saipem using the Saipem 7000 vessel and features a Hitachi Energy HVDC system developed to transmit power more efficiently than traditional AC systems. The platform will receive 1.2GW of AC power generated by the 95 offshore wind turbines of Dogger Bank B, before converting it to DC for transmission to an onshore converter station located near Beverley in East Riding of Yorkshire.

The first platform was installed at Dogger Bank A in April 2023, representing the first time this technology has been used in offshore wind in the UK. All three platforms will be controlled from shore and feature a lean design, resulting in a 70% weight reduction per MW compared to previous platform designs.
