BLAST, FIRE, AND HYDROCARBON CAPTURE AND PROTECTION SYSTEMS
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 61/844,740, filed July 10, 2013, which is incorporated herein by reference.
BACKGROUND
[0002] The present disclosure relates generally to blast, fire, and hydrocarbon capture and protection systems for drilling rigs. More specifically, in certain embodiments, the present disclosure relates to lightweight blast and fire protection systems for drilling rigs that are capable of diverting the flow of hydrocarbons from a blowout and associated methods.
[0003] During the drilling of production wells, conditions may arise which cause an influx of hydrocarbons into the wellbore. Normally a blowout preventer (BOP) and associated equipment and procedures may be utilized to safely limit the influx of hydrocarbons into the wellbore and to safely circulate the hydrocarbons out of the wellbore in a controlled manner. Should the BOP or other equipment completely fail, an uncontrolled flow of hydrocarbons could occur from the wellbore. This is commonly called a blowout.
[0004] Some blowouts maybe contained by installing a capping stack, which is a separate BOP, above the wellhead or the original failed BOP. The capping stack may then be closed, thus controlling the well.
[0005] In some blowouts, the BOP and wellhead equipment may be destroyed or the well may catch fire. In such cases, it may be difficult to contain the blowout by closing valves or other blowout preventers at the surface. Other methods to contain the blowout may be utilized in such cases. A common practice in controlling such a blowout is to drill a relief well which intercepts the formation feeding the blowout. However, while drilling the relief well, oil and gas may continue to be spilled into the environment.
[0006] It is desirable to provide a system that prevents the spillage of oil and gas from a wild well into the environment.

Hydrocarbons from riser 330 may flow upward within the hollow center of gravity based substructure 340 allowing the gas and oil to separate. The gas may then flow through a capture and venting system or a flare system. The oil may gather on the top of the water within gravity based substructure 340 where it may be temporarily stored subsequent offloading via a tanker vessel, oil export pipeline, injected to a well, or other means.
