Description

This report has been prepared by Subacoustech Ltd for COWRIE. This report details a series of underwater noise measurements undertaken during drilling operations for the pin piles used to secure the quadropod base of the SeaGen tidal turbine device in Strangford Lough, Northern Ireland. The results have been interpreted in terms of the potential impact this noise may have on marine species. Background noise measurements were also undertaken during periods when the drilling was not being carried out to determine pre-existing ambient underwater noise levels in the region.
It had been intended to include measurements of underwater noise generated by high pressure water jet cutting at the Strangford Lough site. The installation procedure for the construction project however, was changed and this technique was not required
