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 February 23, 2015, BSEE data indicates that there are 241 platforms which fit the criteria ofidle iron. In addition, there are currently 294 platforms on expired or terminated leases.
    • Of the 535 platforms eligible for decommissioning, 396 are located in water depths less than 100 feet
    • Of the 535 platforms, 130 are located in water depths from 100 to 500 feet
    • Of the 535 platforms, 9 are located in water depths 500 to 5,000 feet
    • Of the 535 platforms, 0 are located in water depths greater than 5,000 feet

Statistics For Artificial Reefs On The Federal OCS

  • As of June 1, 2015, there are more than 500 approved Reef Sites on the Federal OCS. A majority of the TX and LA reef sites contain Rigs-to-Reef; however the MS, AL, and FL reef sites primarily contain other artificial reef materials.
  • Texas Approved Reef Locations:
    • - General Reef Planning Area (contains 24 Reef Sites)
    • - Artificial Reef Planning Zones
    • 63 - Reef Sites
     
  • Louisiana Approved Reef Locations:
    • 9- Artificial Reef Planning Areas
    • 76- established offshore reefs broken down by type:
      • 48- Planning Area Reefs
      • 19- SARS ( there are 3 pending final establishment to bring the total to 22) Special Artificial Reef Sites (SARS; Reef Sites outside of the Artificial Reef Planning Areas)
      • 8- Deepwater Reefs (Reef Sites in >400 feet outside of the Artificial Reef Planning Areas)
      • 1- Nearshore Reef (New reefs developed between the coastline of Louisiana and the 100 foot depth contour)
       
     
  • Mississippi Approved Reef Locations: 
    • 1- Artificial Reef Development Zone (makes up the entire OCS off of Mississippi out to the EEZ)
    • 15 - Reef Sites
     
  • Alabama Approved Reef Locations:
