Scroby Sands

On 15 August 2023, turbine T06 at the Scroby Sands offshore wind farm caught fire in the nacelle, destroying its generator, gearbox and blades and resulting in total loss of operation of that turbine; the incident also required six neighbouring turbines to be taken out of commission for about a week until cables at the site could be isolated, after which the damaged nacelle, blades and upper tower section were later deconstructed and sent to EMR for high‑rate material recycling under RWE’s circular‑economy programme.

CRC Walrus amphibious crew transfer vessel entered service at Scroby Sands after completing land and sea trials; Commercial Rib Charter said RWE would deploy the vessel at the end of the week of 2 Feb 2023, indicating the operational start slipped from the previously planned September 2022.

In late 2015, Norfolk Marine installed its TFN scour remediation system on five monopile foundations at E.ON’s Scroby Sands offshore wind farm, deploying sediment‑retention nets around the bases to prevent further seabed scouring and to protect cables at the critical transition between the export cable trench and J‑tubes, following development and scale‑model testing at HR Wallingford’s Fast Flow Facility.

During the summer of 2008, Osiris Marine Services carried out a major repair and replacement campaign on one of the three 33 kV export cables for the Scroby Sands offshore wind farm connection to Great Yarmouth. Working for Oceanteam Power and Umbilical, divers deburied the existing export cable, recovered the redundant section, supervised laying of a new export cable, and then used OPU’s vertical injector and diver operations to rebury the cable up to the I-tube, completing the subsea tie-in and shore-end works.

Export cable replacement/repair campaign for one of Scroby Sands’ three export cables was executed during the summer of 2008, including deburial, recovery of the redundant cable, laying the new cable, reburial and shore-end/tie-in works (diving support provided during the campaign).

By 21 January 2008, one of the three high‑voltage export cables bringing power ashore from the Scroby Sands offshore wind farm had failed, reducing export capability, although E.ON reported that around 95% of the energy generated could still be delivered via the remaining two cables.

In summer 2007, E.ON excavated part of the promenade on Great Yarmouth’s North Parade to repair one of Scroby Sands’ 33 kV export cables after moisture ingress at an onshore connection joint caused the cable to fail, with one worker treated in hospital for burns from an electrical flash during the repair works.
