WHAT'S HAPPENING OFFSHORE
Throughout summer and late 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 combined LiDAR technology and aerial photography technique.
The first of two unexploded ordnance (UXO) investigations and clearance campaigns took place in late 2021 in the nearshore area with the second due in summer 2022 along the remainder of the cable route and at the wind farm array site. In terms of offshore construction activity, while the main works will not begin until 2023, the installation of the ducts for the export cables will take place in summer 2022 using a horizontal directional drilling technique. Seabed surveys will take place in advance of the duct installation.
