The assessment was undertaken by Headland Archaeology (UK) Ltd. on behalf of Seagreen Wind Energy Ltd. The purpose of the report is to outline the archaeological potential of the marine environment and identify any sites and areas of archaeological significance within and in proximity to the proposed Seagreen Projects. The assessment has established that there are no Designated Wrecks or other cultural heritage assets with legal designations within the Seagreen Projects. The report identified two ‘Dead’ wrecks (HA 1004 and HA 1008) and one ‘Lift’ wreck (HA 1005) within the Project Alpha 1km Outer Study Area zone. No cultural heritage remains were identified in the Project Alpha Inner Study Area. Two ‘Live’ wrecks (HA1001 and HA 1004) and two ‘Dead’ wrecks (HA 1002 and HA 1003) were identified from the Seazone dataset within the Project Bravo site Inner Study Area. No cultural heritage remains were identified in the Outer Study Area. In the Transmission Assets Project four ‘Live’ wrecks and one ‘Dead’ wreck were identified within the Inner Study Area and three ‘Live’ wrecks and four ‘Dead’ wrecks in the Outer Study Area from the SeaZone dataset. In addition, a large number of sites recorded in the National Monument Record of Scotland for the study area without precise locations. As such, there is a moderate potential for the discovery of unexpected remains to be discovered within the development. The archaeological geophysical assessment identified five targets of High archaeological potential and eighteen targets of Medium archaeological potential within Projects Alpha and Bravo. In Project Alpha nine targets of Medium archaeological potential were identified in the Inner Study Area and three targets of medium archaeological potential in the Outer Study Area. In Project Bravo four targets of high archaeological potential and four targets of medium archaeological potential were identified in the Inner Study Area and one target of high archaeological potential and two targets of medium archaeological potential in the Outer Study Area. In the Transmission Assets Project nine targets of high archaeological potential have been identified and eighteen targets of Medium archaeological potential. Eight targets of high archaeological potential and twelve targets of medium archaeological
