Miller Decommissioning Programme

Abstract

From the Recommendations: “The wells are plugged and abandoned. Removed items are returned to shore for reuse, recycling or disposal. The topsides modules are removed and returned to shore for reuse, recycling or disposal. The jacket is removed down to the top of the jacket footings and returned to shore for reuse, recycling or disposal. The jacket footings and the drilling template are left in place. The pipelines are flushed clear of hydrocarbons and left in situ for possible future use. Pipeline spools, umbilicals, SSIVs and structures associated with platform removal activity are removed and returned to shore for reuse, recycling or disposal. The cuttings pile is left in situ to degrade and to allow the seabed to recover naturally. Following completion of decommissioning work a seabed survey is undertaken to identify oilfield related debris within the platform 500m zone, and a 200m corridor along each pipeline up to 100 m outside the pipeline isolation point. All items of oilfield debris identified will be categorised and, in consultation with DECC, a management plan will be agreed.”
