JF Renewables completes first part of ordnance probe


James Fisher Renewables has completed the first part of a two-phase contract to investigate unexploded ordnance and possible archaeological features ahead of the installation of export cables for RWE’s Sofia Offshore Wind Farm.

In September and October 2021, JF Renewables investigated 35 near-shore targets to assess the need for disposal. Remote investigation and disposal are key to safeguarding people and assets during construction and operation phases.

Phase two will begin in early 2022 and will use a low-order disposal technique to minimize noise and to remove any UXOs to protect marine mammals and sea life.

The Sofia Offshore Wind Farm is off the northeast coast of the U.K. As the U.K. aims to construct offshore wind to reach its 40 GW target of electricity using wind by 2030, disposal solutions will become increasingly important.

“We are delighted to be continuing our established and successful relationship with RWE on the Sofia Offshore Wind Farm.

Following a thorough investigation of this particular route, we successfully confirmed all scoped targets as non-UXO,” said Wayne Mulhall, JF Renewables’ managing director. “Our expertise gained from performing more than 3,000 UXO investigations around the globe enabled us to identify additional targets requiring survey, helping us to ensure phase one of the work was completed to the highest standard with the greatest regard for safety for all those involved.”
