Ordtek and OrbisEnergy have produced an interactive map providing information on the location of unexploded ordnance around the UK coastline to help the developers of offshore wind farms.

The map shares data about areas mined by the British and Germans during the wars, plus unexploded ordnance from military armament training and munitions dumping, as well as previous UXO finds.


The Mine Map currently covers the UK exclusive economic zone, but will be extended in the future to cover more European waters.

The companies said it combines a range of data sources, including information from the UK National Archives, the Hydrographic Office and archives in Europe. Ordtek has also liaised with military sources.

Ordtek director Lee Gooderham said: “We have been working all over Europe and thought it was a good idea to share data about offshore unexploded ordnance to help developers.

“Geophysical seabed surveys, including looking for potential UXO, are a routine part of assessing sites ahead of construction work.

“It’s not the complete database, although finer detail will be available at a later date.

“However, it is helping developers to understand UXO hazards while making their initial tender bids for wind farm sites and it's allowing vessel operators to begin risk assessments.

“It helps them to see how much potential unexploded ordnance there is in an area, and work out how much it might cost to dispose of it.”
