WHAT'S HAPPENING OFFSHORE
Throughout summer 2021, Sofia was busy with offshore surveys as part of the project's pre-construction commitments and site preparation works.
The works included the pre-construction benthic survey programme, investigation of an archaeological feature found during a previous geophysical survey and the start of pre-construction bird surveys using a new technique combining LiDAR technology and aerial photography data.
The first of two unexploded ordnance (UXO) investigations and clearance campaigns starts in September with the second due in 2022. Potential UXOs will be investigated, identified and, if confirmed, removed prior to construction using innovative methods to reduce underwater noise impacts to marine mammals and fish. Any UXOs found are likely to be British buoyant mines or German ground mines from WW2. This work will also include further archaeological investigations, as well as underwater noise monitoring.
