Decommissioning the Greater Dunlin Area

The decommissioning of the Greater Dunlin Area represents an opportunity for our teams of onshore professionals and the offshore workforce to tackle new and fresh challenges as the industry moves into a new era.

The overall project from cessation of production to final site remediation is a multi-year undertaking. Throughout each of the main project stages, the associated activities have been planned in consultation with relevant stakeholders. These stakeholders have included industry regulators, other users of the marine environment and the communities in which we operate. The consultations that were initiated in 2010 for specific aspects of the proposed decommissioning programme have been the backdrop for a collaborative process to determine the most appropriate solutions for the decommissioning challenges that balance considerations for the environment, safety, technical feasibility, and socio-economic impact.

The aim has been to ensure that the decommissioning of the Greater Dunlin Area is concluded with a responsible legacy to both the environment and society as the reliance on alternative energy resources becomes more prominent.

The project objective in terms of scope has been the safe and cost-effective execution of activities in full compliance with the approved Decommissioning Programmes.
