Don Field Decommissioning ProgrammeDON-BP-001The immediate area of the Don manifold was characterised by more highly reflectivesediments comprising a superficial cover of coarse sands with exposures of theunderlying stiff clays of the Tampen Formation, together with boulders and a numberof depressions. Grab samples indicated the sediment to be poorly to very poorly sortedsand and silt. Particle sizes taken in grab samples were indicative of the distribution ofcuttings over the seabed.Refer to Section 8 for further details.4.2 Other MaterialsAny oilfield-related material, not covered by permit, remaining on the seabed followingdecommission will be so identified and removed during the final site clearance activities(refer to Section 16 for further details).5 References[4.1] Don Field Trawl Damage Repair As-built Report, Stolt Offshore Limited,Doc No RE-ENG-397-303.
