One such area of challenge is the final disposition of the Dunlin Alpha Concrete Gravity Base Substructure (CGBS). To better understand stakeholder perspectives on this issue, a specific programme of stakeholder engagement was initiated in January 2010. This programme involved a series of stakeholder workshops, the formation of a Cell Contents Expert Discussion Group (CCEDG), consultation with various OSPAR contracting parties, and a series of one to one meetings with certain stakeholders.
This engagement drove a significant technical study over a two year period, culminating in a Comparative Assessment of the available options for decommissioning of the Dunlin CGBS and the development of a preliminary draft Dunlin Alpha Decommissioning Programme.
Following the announcement of Cessation of Production in mid-2015, we have renewed our stakeholder engagement efforts. A major programme has re-explored decommissioning concepts and options to gain their perspectives from a wide range of stakeholders, building on the contact during earlier years, most recently on the Dunlin Alpha concrete gravity base substructure, resulting in the submission in August 2018 of a Draft Decommissioning Programme on which a six-week formal consultation was held.
Following the consultation period, and in agreement with OPRED, it has been decided to split the Dunlin Alpha Decommissioning Programme and Environmental Appraisal into two separate programmes, addressing the topsides and substructure respectively.
