Method of rig-to-reef decommissioning by partial removal Method of rig-to-reef decommissioning by toppling in place. Severing the rig from the bottom using explosives is the easiest approach, but has the potential to harm marine life. This potential is greatly reduced if the explosives are all placed deep below the seafloor.
The first strictly offshore oil field in California was the Belmont Offshore Field, discovered in 1948 1.6 miles (2.6 km) from the shore of Seal Beach; production did not begin until 1954 when a man-made island was built in 40 feet of water for drilling and production equipment.
The Brent pipelines decommissioning programme was approved by the UK government in March 2020. As per the decommissioning plan, the gravity-based structures (GBS) of Delta, Charlie, and Bravo platforms, the jacket footings of Alpha platform, drill cuttings, and the GBS cell contents will not be removed from the field. The GBS subsea storage ...
Less offshore decommissioning work was carried out last year despite the overall amount of money being spent on the activity increasing, the industry has said. Offshore Energy UK (OEUK) said £1.7 ...
But as of June 2023, more than 2,700 wells and 500 platforms were overdue for decommissioning in the Gulf of Mexico, according to the U.S. Government Accountability Office. The Department of ...

Platforms would then only be visited infrequently for integrity checks and maintenance of temporary equipment left for power requirements and safety functionality. The platform would then remain in this phase until further decommissioning activities are carried out to remove the topsides in modules or piece small, then remove the jacket .
Offshore drilling has continued from existing platforms in state and federal waters. State offshore seabed in California produced 37,400 barrels (5,950 m 3 ) of oil per day, and federal offshore tracts produced 66,400 barrels (10,560 m 3 ) of oil per day in November 2008.
