Lincoln archaeology firm to dig 300 trenches as part of Triton Knoll project

This story is over

Lincoln firm Allen Archaeology will begin digging around 300 archaeological trial trenches this month as part of work as part of the Triton Knoll Offshore Wind Farm project.

Allen Archaeology will dig trenches and survey the area using metal detectors. Trenches will be approximately 2m wide and up to 50m long in places, and visible across local fields.

The works are part of a programme of surveys being funded by and undertaken for Triton Knoll, a partnership between energy companies innogy SE which is managing the project on behalf of the partnership and Statkraft, as the project continues to map out its onshore construction programme.

The project will be located approximately 32km off the Lincolnshire coast and 50km off the coast of North Norfolk. It has consent to install almost 60km of onshore underground export cable, an Intermediate Electrical Compound at Orby and a new substation near Bicker Fen.

While the surveys are important to the wind farm construction, they also form part of one of the largest archaeological explorations of the local area.

The substantial preconstruction work will take place along the entire length of the project’s almost 60km long onshore cable corridor – including fields adjacent to the landfall location, the onshore substation and the Intermediate Electrical Compound sites.

The results will ensure any archaeological sites are sensitively and appropriately managed during future construction works.

Triton Knoll Project Director James Cotter, said:

“This is a really valuable and interesting programme of investigations for the project and also for the local area.

“This latest round of survey works is our most significant onshore activity to date, and marks another important step towards ensuring Triton Knoll is construction ready by the time we reach a final Financial Investment Decision.”

Mike Wood, at Allen Archaeology, who is leading the works for Triton Knoll, said: “We anticipate the works potentially taking approximately five months, and expect the bulk of the work to take place during late summer and early autumn.”
