Mine Map - Offshore UXO Contamination

The underlying aim of the map is to share knowledge and sources of offshore UXO contamination and Ordtek would welcome contributions from any other party.

User Notes

  • Mine Map is a free to use, interactive tool displaying offshore UXO contamination - currently confined to the UK Exclusive Economic Zone (EEZ) displayed on Mine Map, with more coming in 2019.

  • Data displayed within Mine Map provides a representation of sources of UXO contamination but is not the full extent of Ordtek’s offshore UXO database and does not show all sources of UXO contamination. For illustration purposes and usability Ordtek have rationalised the data, much finer detail is available from Ordtek and can be provided on request.

  • Mine Map is an indicative tool and does not constitute a full UXO hazard and risk assessment which should be undertaken by a UXO specialist.
