Metadata: 2007, COWRIE, Assessment and costs of potential engineering solutions for the mitigation of the impacts of underwater noise arising from the construction of offshore windfarms
Abstract:
This reports reviews the possibilities to mitigate the noise arising from pile driving for the construction of offshore windfarms. It analyses mitigation measures which have been applied in related projects and assesses their applicability to offshore pile driving. Based on this, suggestions for new mitigation measures are made. The report identifies two methods which are promising to be both applicable and effective in reducing underwater noise arising from offshore pile driving. Both methods are considered to be generally compatible to the working processes at sea. Although further engineering work would be needed, they could be brought into practice within a few months. It is concluded, that noise mitigation measures offer good opportunities to reduce the impacts of underwater noise arising from the construction of offshore windfarms. For the offshore industry, noise mitigation may prove to be beneficial as their application may allow construction works in areas and times when restrictions are needed to protect sensitive species.

All acronyms and abbreviations should be reproduced in full. | 2007, COWRIE, Assessment and costs of potential engineering solutions for the mitigation of the impacts of underwater noise arising from the construction of offshore windfarms |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 739a052fe37c54be81e183eae86e9bc3 |
| Resource Identifier | This is the code assigned by the data owner. | 3229 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2026-04-19 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2026-04-19 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This reports reviews the possibilities to mitigate the noise arising from pile driving for the construction of offshore windfarms. It analyses mitigation measures which have been applied in related projects and assesses their applicability to offshore pile driving. Based on this, suggestions for new mitigation measures are made. The report identifies two methods which are promising to be both applicable and effective in reducing underwater noise arising from offshore pile driving. Both methods are considered to be generally compatible to the working processes at sea. Although further engineering work would be needed, they could be brought into practice within a few months. Based on measurements of offshore pile driving, noise emissions of large piles are estimated to reach peak levels of 201-205 dB re 1µPa and sound exposure levels SEL of 175-178 dB re 1µPa at a distance of 500 m. Noise produced from offshore pile driving may be harmful and disturbing to marine wildlife. From literature data it is inferred, that physical impairment may occur above levels (SEL) of 180 dB re 1µPa. As a first proxy for disturbance of marine mammals, the report refers to a level of 140 dB re 1µPa. |
