Offshore Drilling Accidents

Major offshore platform and drilling accidents in the oil and gas industry.

Rigsworld
 

Below you will find a short overview of offshore drilling accidents during the offshore oil and gas activities since 1964.

To a certain extent, each accidental situation develops in accordance with its unique scenario.
The most typical causes of accidents include equipment failure, personnel mistakes, and extreme natural impacts (seismic activity, ice fields, hurricanes, and so on). Well blowout during drilling from offshore oil platform, have caused some and sometimes very large oil spills.


C. P. Baker drilling barge
C. P. Baker drilling barge burned and sank after a shallow gas blowout. Of the 43 crew on board, eight were confirmed dead with 13 missing, presumed dead and 22 injured.

Union Oil's Platform A
The Santa Barbara oil spill occurred in January and February 1969 in the Santa Barbara Channel, near the city of Santa Barbara in Southern California. It was the largest oil spill in United States waters at the time, and now ranks third after the 2010 Deepwater Horizon and 1989 Exxon Valdez spills. It remains the largest oil spill to have occurred in the waters off California. In January of 1969, Union Oil began drilling a fifth oil well on their offshore Platform A, just over five miles from the coast of Santa Barbara, CA. On the morning of the 28th, drilling stopped for well evaluation. At 10:45 a.m., the well blew out, leaking oil and gas. A second blow out in a different well followed on February 24th.

West Atlas Drilling Rig
It is considered one of Australia's worst oil disasters. The West Atlas mobile drilling rig leaked oil and gas into the East Timor Sea from the Montara oil field near Australia, and later sank after a fire. The spill continued for months before relief wells were drilled to plug the leak, depositing millions of gallons of crude into an ecologically sensitive marine ecosystem. The West Atlas rig is owned by the Norwegian-Bermudan Seadrill, and operated by PTTEP Australasia (PTTEPAA), a subsidiary of PTT Exploration and Production (PTTEP) which is in turn a subsidiary of PTT, the Thai state-owned oil and gas company was operating over on adjacent well on the Montara platform. The slick was released following a blowout from the Montara wellhead platform on 21 August 2009, and continued leaking until 3 November 2009 (in total 74 days), when the leak was stopped by pumping mud into the well and the wellbore cemented thus "capping" the blowout.
