Noise

Description

In order to support E.ON's request for the modification of seasonal restrictions on piling at the Rampion Offshore windfarm, HR Wallingford was commissioned to examine underwater noise propagation arising from a reduction in the proposed hammer energy. The results of these studies are reported in DLR5374- RT001-R03-00 (underwater noise modelling), DLR5374-RT002-R02-00 (Seasonal restrictions review) and DLR5374-RT004-R01-00 (Reduced hammer energies). Following a review of that work by the Marine Management Organisation (MMO), E.ON asked HR Wallingford to re-analyse the previous model results for marine mammals and herring using different metrics to allow for comparison of the modelling with that described in the original EIA for the Rampion project (RSK Environmental Ltd, 2012). The results of these studies are reported on in DDM7600-RT007-R01-00 and DDM7600-RT004-R01-00. Further modelling was also undertaken to assess the effects of simultaneous piling events at two locations (both 2no. x 2300kJ, and 1no. x 2300kJ, 1no. x 3500kJ).
