Fugro will deploy two of its fixed magnetic gradiometer array Geowing systems, each equipped with 10 magnetic sensors to detect potential UXO and other objects on or under the seafloor.

The survey will generate geo-data for mapping potential targets and devising a master target list for further investigation.

Further inspection and identification activities will follow in 2028, using ROV technology and other detection systems to investigate selected targets and remove debris where needed.

In addition, Fugro will support removal and disposal of any confirmed UXO in compliance with regulatory requirements.

Ronny Bøhn, director of Marine Geophysics for Europe and Africa, said:

“On a project of this scale, the challenge is that the number and nature of potential UXO can only be known once the survey is complete.

Building a reliable picture of the seabed at an early stage will allow 50Hertz to plan the next steps with greater certainty and manage safety throughout the cable installation program.”
