This report contains the operation details and results of the Lynn and Inner Dowsing Windfarm Mono Pile Foundation pre-construction side scan sonar debris clearance survey carried out for MT Højgaard A/S commisioned by Centrica. The fieldwork was undertaken between the 20th March and the 10th May 2007 by Fugro Survey Limited, using the M/V Genesis. Work consisted of a SSS survey to determine any seabed contacts within an area encompassing all 60 proposed monopile locations for the Lynn and Inner Dowsing Windfarm. It was proposed that lines are performed nominally every 40 metres in the mainline orientation with cross lines nominally every 200 metres. Mainlines are also run 20 metres offset from each monopile location with a cross-line again offset by 20 metres from each location. The Service Warranty in Appendix E outlines the limitations of this report.
