Electronic Monitoring System

We are tasked by both the Marine Management Organisation and the Welsh Assembly Government to provide information supplied by the Electronic Monitoring System (EMS). This system must be installed on all vessels dredging for marine minerals in British waters, as required under:

  • the Environmental Impact Assessment and Natural Habitats (Extraction of Minerals by Marine Dredging) (England and Northern Ireland) Regulations 2007
  • the Environmental Impact Assessment and Natural Habitats (Extraction of Minerals by Marine Dredging) (Wales) Regulations 2007.

Our role

We provide data, based on the information automatically collected from the EMS equipment installed on dredging vessels, and report any identified discrepancies to the relevant regulatory authorities. The Crown Estate continues to monitor EMS data for their own purposes and provide a helpdesk facility for EMS operators.

We do not undertake investigation or enforcement activities on behalf of the regulatory authorities. As such, our role is very much "behind the scenes", so industry representatives should not expect to hear directly from Cefas regarding EMS.

Should you know of a specific out-of-area dredging incident and wish to make us aware of that, please email us with the supporting information. Your email should be marked for the attention of the EMS Manager to ems@cefas.co.uk.

For further information or general queries regarding our role in the EMS, please contact marineaggregates@cefas.co.uk.
