This study provided a review of the state of the art decommissioning practices for oil and gas facilities in the U.S. Outer Continental Shelf (OCS). The specific tasks include: (1) Review the planning and engineering costs and methodologies analyzed in the 2009 TAP 'Engineering Cost Assessment for Decommissioning POCS Facilities' and 'Decommissioning: Fixed and Floating Platform Removal and Disposition' report, (2) Conduct research and compare estimated decommissioning costs to actual decommissioning costs which are available both domestically and globally and develop a ratio of Actual/Estimated Cost (AEC) for different types of facilities (conventional, deepwater, floating, etc.) which can be used by the agency for future decommissioning projects., (3) Research and catalogue facility removal techniques and methodologies implemented domestically and globally. (4) Listing and an evaluation of any safety or environmental accidents, incidents or events which happened during actual facility removal operations. (5) Catalogue of offshore decommissioning and facility removal methodologies and techniques employed globally and domestically. (6) Catalogue of cost ranges (7) Catalogue that provides an analysis of decommissioning procedures, techniques, equipment, costs, etc. on a global basis (8) Analyze the different decommissioning and facility removal regulations and compare and contrast these with BSEE requirements.
