DEA seeks feedback on North Sea Ravn decommissioning submission

The Danish Energy Agency (DEA) has made available Wintershall Nordzee’s environmental impact report for decommissioning of the Ravn Field in the Danish North Sea.

This will be Denmark’s first experience of a full decommissioning of an oil and gas field. The public, including Danish authorities and organizations, have until Dec. 1, 2023, to submit comments and questions to the DEA.

Ravn’s platform and associated installations were constructed in 2015 and are in permits 5/06 and 2/16, 245 km from the Danish coast and 15 km from the German offshore median line. The platform is connected to two subsea pipelines and a supply line linked to the A6-A platform in the German sector.

Two suspended production wells connected to the Ravn platform are no longer in service. Wintershall Nordzee has applied for permission to permanently shut in the wells, subject to an independent environmental assessment, prior to decommissioning of the platform.

In addition, Denmark has undertaken to remove installations in its sector of the North Sea built for the extraction and transport of oil and gas. This means the platform and associated installations must be dismantled and removed to be transported ashore for scrapping or recycling.

Pipelines are not subject to this obligation, so the DEA must assess whether they should be decommissioned in-situ following cleaning, or removed and transported ashore.
