Hornsea Offshore Wind Farm Projects 1 and 2
SmartWind (Mainstream / Siemens Joint Venture)
RPS undertook baseline noise surveys, developed detailed models, provided assessments and authored the Technical Report for the offshore wind farm and Noise and Vibration ES Chapter for the onshore grid connection, cable route and horizontal directional drilling activities. The project is in progress and has incorporated parallel assessments of two grid connection designs (HVAC and HVDC).
Key to this process has been the ability to design, and assess, a worst-case scenario to enable the project design team maximum flexibility on the equipment specification, anticipating potential design amendments during the equipment procurement phase, without compromising neighbour amenity at any stage in the project life-cycle, though to future site decommissioning.
The noise assessments of the offshore wind farm included models that considered acoustic propagation over water and across large distances, which is out with the scope of the methodology commonly adopted for wind farm assessment in the UK (ISO 9613-2).
