Abstract

This note provides a summary of the commercial and operational implications that are considered by offshore wind projects when assessing the feasibility of deploying different Noise Management Methods (NMM). This is a broad term which captures both Noise Abatement Systems (NAS) that are technologies which attenuate the underwater noise that is produced (e.g. bubble curtains) and Noise Mitigation Systems (NMS) that are designed to reduce the production of noise at source (e.g. Hammer attachments). Feedback from offshore wind project developers has been collated by the Offshore Wind Industry Council’s Environment and Consents (OWIC E&C) team for the purpose of informing the development of policy on marine noise and supporting well informed consent and licence decisions. 

This note is limited to the commercial implications of different NMM, however developers have also shared information on NMM efficacy and wider environmental issues which is being used to support our understanding of the potential broader ecological implications of different NMM. 

The collated feedback serves to demonstrate, through information provided by live projects in development, construction and operation phases, the wider project implications resulting from the new requirement to deploy NMM for projects from 2025 onwards. It also provides evidence to inform the feasibility of any future decibel limit currently under consideration.
