4C Offshore Empowering Intelligence

Pentland Floating Offshore Wind Demonstrator

07 Mar 2022: The project will be awarded the consent variation and has been advised that an EIA is not required. The Proposed Works involve decreasing the number of WTGs for construction from two to one and the removal of the individual capacity limit of 6 megawatts (“MW”) and total generating capacity limit of 12MW from the Section 36 Consent. This will entail dimensional changes in WTG design, increasing the tip height from 201 metres (“m”) to 208m, rotor diameter from 154m to 179m and the height of the floating platform above water from 15m to 30m. Additionally, the proposed works involve an increase in the distance of the WTG from shore to approximately 8.28km, and this should be applied for as part of the variation to the section 36 consent. The Proposed Works further involve the separation of the single clump weight suspended in the water beneath the floating platform into multiple separate weights and the inclusion of suction bucket and drilled and grouted anchoring solutions, in addition to the previously licensed drag embedment anchors. This will also involve the inclusion of a taut mooring system option and the inclusion of a synthetic lines option, as well as the currently licensed chain and/or steel lines. The export cable voltage will also be increased from 33kV to 66kV. The conclusion of the assessment on environmental receptors undertaken by Highland Wind Limited, including updated ornithological collision risk modelling, contends that the Proposed Works would not lead to a greater significance of environmental impacts on receptors than already authorised by the Section 36 Consent and Marine Licences. It is contended that the effects on marine ornithology and seascape, landscape and visual amenity will reduce as a result of the reduction from two WTGs to one. It is also contended that the taut mooring system will reduce the environmental effects of fish ecology and marine mammals.
