    "description": "The Food and Environment Protection Act (FEPA) Licence (33097/07/0) for the Greater Gabbard Offshore Wind Farm (GGOWF) required the subsea noise during the operational phase of the wind farm to be measured to assess \u2018various frequencies across the sound spectrum at a selection of locations immediately (adjacent to), within and outside the array at varying distances\u2019. The full wording of licence condition 9.9 is stated below:\r\n\r\n\u2018The Licence Holder must make provision during the construction phase of the wind farm to install facilities to enable subsea noise and vibration from the turbines to be assessed and monitored during the operational phase of the wind farm. Before completion of the construction phase the Licence Holder must specify how it proposes to measure subsea noise and vibrations to the Licensing Authority in order to fulfil the monitoring requirement outlined in Annex 1 attached to this Licence. The specification must include assessment of various frequencies across the sound spectrum at a selection of locations immediately, within and outside the array at varying distances.\u2019\r\n\r\nAlthough the licence condition sates \u2018monitoring\u2019 as a requirement, in situ measurements alone may not necessarily result in an increase of understanding of the potential noise resulting from GGOWF, compared with background or ambient noise in the area. Evidence from the Gunfleet Sands offshore wind farm (Nedwell et al., 2011) suggests that the type of wind turbine operating at GGOWF is not very \u2018noisy\u2019 compared with typical coastal ambient noise. This may particularly be the case around the GGOWF site where the density of surface vessel activity is relatively high.\r\n\r\nThis report describes work carried out by the National Physical Laboratory (NPL), on behalf of Greater Gabbard Offshore Winds Limited, to assess the likely noise levels resulting from operation of the entire GGOWF, with a methodology that is considered most appropriate to address the underlying requirements of the relevant licence condition.",
