The Dudgeon Offshore Wind Farm (DOW) is located c. 32km off the coast of Cromer in North Norfolk with an export cable route running in an approximately south westerly direction from the wind farm to a landfall at Weybourne Hope on the North Norfolk coast. Pre-construction archaeological assessments included the assessment of marine geophysical data, geoarchaeological assessment and the review of data acquired during Remote Operated Vehicle Survey as part of UXO investigation and clearance. Monitoring was also undertaken comprising the archaeological assessment of post-construction marine geophysical data. Assessment was undertaken by Wessex Archaeology and the retained archaeologist was Royal HaskoningDHV. The approach to addressing archaeological considerations for DOW represents the early application of an approach now commonly applied to offshore wind farms and generally accepted as good practice across the industry. For submerged prehistoric studies this involves using the archaeological interpretations of the project's seismic and bathymetric data alongside geotechnical data to develop a deposit model which can then be tested through geoarchaeological analysis/palaeoenvironmental analysis. A staged approach which allows research questions to be established and then tested at every stage means that original interpretations (in this case, that the deposits were indicating evidence for the Storegga Slide) may be disproven by dating and other scientific analysis. For seabed features, the approach to identifying anomalies through the archaeological assessment of preconstruction marine geophysical data followed by ground truthing using divers or ROVs, generally in conjunction with UXO investigations, is now considered standard across the offshore wind industry. The results of the work undertaken for DOW show that the approach to discrimination between low and high potential anomalies does correlate with the results of ground-truthing, with lower potential anomalies (< 50nT and < 3m) being far less likely to represent significant archaeological features that those discriminated as higher potential anomalies. In conclusion, archaeological assessments undertaken prior to construction for DOW successfully demonstrated the presence of both maritime and aviation remains which informed the avoidance strategy so that impacts to archaeological material could be avoided during construction. It was also noted that building upon the approach applied to DOW, further industry wide strategic studies and lesson's learned will likely be required in order to better establish a standard approach to post construction monitoring.
