Estimates have been made of potential impact zones around the array based on previously recorded data of similar operations. For all species of fish the data indicate that will be no cumulative effects between adjacent turbines. For species of marine mammal, where the impact ranges are predicted to be larger, there are likely to be some cumulative effects between the turbines. For harbour porpoise the majority of the Kyle Rhea site will be insonified by levels in excess of 90 dB ht , resulting in a strong avoidance reaction, however in fast flowing waters such as Kyle Rhea, it is not uncommon for background flow noise in excess of 90 dBht for harbour porpoises.

These data have been used to estimate the Source Levels and Transmission Losses associated with the drilling operation. The data have then been directly scaled up for the more powerful device based on the manufacturers specifications of the two drilling devices. While some uncertainties do still remain when using this approach, it is felt that it offers the best estimate of potential levels of underwater noise possible based on the currently available information.
