Statistics for Decommissioned Platforms on the OCS

  • As of May 31, 2013, there are approximately 2900 production platforms on the U.S. Outer Continental Shelf (OCS). Production platforms are the structures located offshore from which oil and natural gas are produced. Unlike drilling rigs, which typically move from location to location, production facilities remain in the same location throughout a project's duration. 
     
  • As of June 11, 2013, BSEE data indicates that there are 356 platforms which fit the criteria of idle iron. In addition, there are currently 273 platforms on expired or terminated leases.
    • Of the 629 platforms eligible for decommissioning, 478 are located in water depths less than 100 feet
    • Of the 629 platforms, 145 are located in water depths from 100 to 500 feet
    • Of the 629 platforms, 5 are located in water depths 500 to 5,000 feet
    • Of the 629 platforms, 1 are located in water depths greater than 5,000 feet
