Abstract:
1. A method for accessing and controlling fluid flow through a subsea well conduit above or below the sea floor, comprising the steps of: enclosing at least a portion of a conduit comprising at least two pipes with a containment system having a containment shell; wherein said conduit is located above or below the sea floor; sealing said containment shell about said conduit to form a pressure barrier between the pressure external to said containment shell and the pressure of the interior of said containment shell; engaging a first pipe of said conduit with a first sleeve of a penetration device that is part of said containment system; penetrating said first pipe of said conduit with said first sleeve by displacing a portion of a sidewall of said first pipe with said first sleeve; extending said first sleeve between said first pipe and a second pipe positioned within said first pipe; attaching said first sleeve to said first pipe; and creating a pressure seal between said first sleeve and said first pipe.
