DescriptionBlowout Preventer (BOP) Cut Away.jpg |
Blowout Preventer from the Ocean Star Offshore Drilling Rig and Museum in Galveston, Texas. "A typical Blowout Preventer stack consists of three remotely controlled sealing assemblies. The blind rams close off the hole after removing the drillpipe, completely sealing off the wellbore. The Pipe rams have half moon shaped cutouts designed to fit around the drillpipe to seal the well while the drill is in the hole. The upper seal of the BOP is the annular. It contains a rubber and steel sealing element that can seal off an empty hole from a slender wireline or drillpipe. The blind rams are powerful enough to cut through the pipe as they seal off the hole in the event of an emergency." |
