As underwater noise generated during construction of wind farms - principally through pile driving - has previously been shown to be of physical risk to marine mammals in close proximity, and the area is known to be utilised by marine mammals, Natural England and DEFRA requested a procedure of mitigation measures against this potential damage. In response CREL commissioned and adopted a project specific marine mammal monitoring protocol (MMMP) for implementation during foundation installation. The basic principle of the MMMP was to ensure that no marine mammals were within 500 metres of the pile during the 30 minute period preceding the start of piling. To confirm their absence two marine mammal observers (MMOs), one of whom operated a passive acoustic monitoring (PAM) system, were to be stationed onboard a crew boat prior to all pile-driving operations. By conducting radial transect surveys around the point of piling the MMO’s could ensure that piling would not commence should marine mammals be detected in the 500 metres exclusion zone in the critical pre-piling period. In addition, a soft start was to be implemented for all piling events. completed Centrica Energy Centrica plc, Millstream, Maidenhead Road Windsor Berkshire SL4 5GD United Kingdom renewables@centrica.com L&ID.DocumentControl@centrica.com http://www.centrica.com/ custodian RPS Energy, Project Manager Goldsworth House,, Denton Way, Goldsworth Park, Woking, Surrey, GU21 3LG, rpsenergy@rpsgroup.com www.rpsgroup.com originator notPlanned Marine Environmental Data and Information Network Marine Environmental Data and Information Network Construction monitoring The Crown Estate Renewable Energy Development Phases 2012-05-15 revision 1 Renewable Energy Lease area The Crown Estate Renewable Energy Development Areas 2012-05-15 revision 1 Cetacean abundance SeaDataNet Parameter Discovery Vocabulary 2018-12-12 revision 110 Acoustic noise in the water column SeaDataNet Parameter Discovery Vocabulary 2018-12-12 revision 110 http://www.marinedataexchange.co.uk/pages/terms-of-use.aspx copyright otherRestrictions copyright otherRestrictions http://www.marinedataexchange.co.uk/pages/terms-of-use.aspx http://www.marinedataexchange.co.uk/pages/terms-of-use.aspx eng biota 0.429574612037093 0.490668789094874 53.1235139054851 53.2139573121939 2007 2008 series Construction phase of the Centrica Renewable Energy Ltd’s (CREL) Inner Dowsing and Lynn offshore wind farms began in April 2007.
