Abstract: |
Wessex Archaeology was commissioned by Royal HaskoningDHV to undertake a post-construction archaeological monitoring assessment of geophysical data acquired from the Dudgeon Offshore Wind Farm by MMT in 2018. This was undertaken to satisfy the conditions for archaeological monitoring as set out in Marine Licence L/2012/00218/10. The Dudgeon Offshore Wind Farm comprises 67 turbines and their associated inter-array cabling, with two export cables. The wind farm covers an area of 55 km² and the export cables are approximately 35 km from the offshore substation to landfall at Sheringham. Wessex Archaeology has been involved in several phases of work for the Dudgeon development since 2009. The assessment data comprised sidescan sonar and multibeam echosounder which were used to assess the presence of seabed features of archaeological potential, and to determine any possible impact (direct or indirect) on previously identified features that may have occurred as a result of wind farm construction. The results of this assessment were compared to the results of the archaeological assessment of data acquired by Osiris Projects in 2012 and 2013 and the subsequent ground-truthing by Remotely Operated Vehicle surveys of potential Unexploded Ordnance. This assessment resulted in a total of 32 anomalies being identified: 24 anomalies have been previously identified and 8 anomalies are newly identified. Where existing Archaeological Exclusion Zones were covered by geophysical data, no evidence was seen of incursions into any of these. All anomalies within the study areas have been classified as A2 and no Archaeological Exclusion Zones are recommended at this time. |
