Abstract
The Carbon Trust, in collaboration with ORJIP Offshore Wind partners, presents the results of the Reducing uncertainty in underwater noise assessment (ReCon) project, which include:
- A review of noise recordings from the installation of offshore wind monopiles and pin piles at 11 offshore wind farms in England, Scotland, the Netherlands and Germany.
- Across all projects, more than 165,000 single strikes were analysed to identify the key parameters influencing impact pile-driving sound level.
- Sensitivity analysis was performed to identify how modelling uncertainties can be reduced.
- Empirical noise recording data was compared with pre-construction modelling for 6 of the 11 projects.
The report provides recommendations on how to improve noise predictions, field measurement design, and cross-project comparisons.
