Blyth Offshore Demonstrator Ltd (BODL) is developing an offshore wind demonstration site off the Northumberland Coast close to the Port of Blyth. The Blyth Offshore Demonstration project (the “Project”) was subject to an Environmental Impact Assessment (EIA) as reported in an Environmental Statement (ES) (NaREC, 2012). Subsequently the Project received a Marine Licence [L/2013/00303 as amended] from the Marine Management Organisation (MMO) to develop and operate the demonstration site subject to satisfying a number of conditions within the Licence. The Project will be comprised of a maximum of 15 wind turbine generators, to be constructed across three arrays (Arrays 2, 3a and 4), on an array-by-array basis along with three associated export cables, resulting in a maximum of three construction phases. The report in this series covers Array 2, the first array to be built. Array 2 is the closest inshore array. To avoid confusion, the naming of Array 2 has been retained to match with historical consent and survey documents. Array 1 was removed from the scheme ahead of consent application. Construction works for Array 2 were undertaken through 2017 and the five turbines became operational in October 2017. The purpose of this document is to report on the results of the first year of post-construction surveys that have been undertaken in March-October 2018 for the Ornithological and for the Marine Mammal Monitoring Programmes that are being implemented to satisfy these licence conditions, for the first phase of the development, the inner (inshore) array of turbines (termed ‘Array 2’ in the ES).
