DON-BP-001Don Field Decommissioning ProgrammeOnce all facilities have been removed, post-decommissioning surveys and oilfield debrisremoval will be carried out to ensure that the seabed is clear of obstructions that mightaffect fishing activities or other users of the sea. The results of the debris clearance shallbe independently verified.An ‘as-left’ survey will be completed to provide a baseline and an inspection regimeimplemented to monitor the status of the pipelines, post decommissioning. As indicatedin Section 10, Paragraph 7 the first survey will be carried out within one year of thedecommissioning work. The second survey will be carried out within three years of theinitial survey and a future survey regime will be determined in conjunction with theDECC, based on the analysis of the first two surveys.An environmental survey of the Don manifold area and pipeline corridor will be carriedout within one year of completion of the decommissioning work with a further surveythree years later. Results of these surveys will be submitted to the DECC and a futuresurvey schedule will be agreed with the DECC.The Don Field owners are committed to perform any remedial action that may beidentified during the future monitoring programme.10 References[2.1] COP Letter from Simon Toole, DECC (BERR) Director Exploration, Licensing,Development and Production to Dr Norrie Ramsay BP DecommissioningManager, dated 3rd February 2005.[2.2] The Convention for the Protection of the Marine Environment of the North-eastAtlantic OSPAR Decision 98/3 on the Disposal of Disused OffshoreInstallations, http://www.ospar.org.[2.3] ‘Don Field: Decommissioning of Pipeline PL981’ letter from the DECC (BERR)to BP, ABE/20/4/13, 20 September 2000.[2.4] Oil & Gas UK Drill Cuttings Initiative, Final Report.
