Calling for entries from companies and consortia interested to progress a research project entitled ‘Reducing conservatism in underwater noise assessments’ (ReCon), created under ORJIP Offshore Wind Stage 2.
Offshore Renewables Joint Industry Programme (ORJIP) for Offshore Wind launched its second stage in July 2019 with the objective of identifying, prioritising and selecting research to reduce consenting risk for offshore wind.
It was identified that some assumptions used in Environmental Impact Assessment (EIA) for determining both source and received noise levels from piling likely contribute to a significant overestimation of the predicted impact ranges for injury and disturbance to marine mammals and fish.
This project will seek to compare real-world data with scenarios modelled during project development to determine the difference between modelled estimates and the actual noise measured during construction. It will also review the real-world underwater noise data measured during piling installation to analyse differences in noise levels, frequency, duration etc. for different piling methodologies and strategies.
Clarification questions should be received by 27 November 2020. Answers to these questions will be posted below by 11 December 2020 at the latest.
The closing date to receive tender submissions is 18 December 2020 17:30 BST.
