Abstract: A hydraulic blowout preventer operator comprises a piston rod having one end coupled to a closure member. The operator further comprises an operator housing having one end coupled to a bonnet and a second end coupled to a head. The piston rod extends through the bonnet into the operator housing where it is coupled to a piston that is disposed within the operator housing. The piston comprises a body and a flange. A flange seal is disposed on the flange and is sealingly engaged with the operator housing. A body seal is disposed on the body and is sealingly engaged with the operator housing. The flange seal has a sealing diameter greater than a sealing diameter of the body seal.

Abstract: A hydraulic blowout preventer operator comprises a first piston rod coupled to a closure member. The operator further comprises a first operator housing coupled to a bonnet and a head. The first piston rod extends through the bonnet into the first operator housing where is couples to a first piston disposed within the first operator housing. The operator further comprises a second piston rod coupled to the closure member. The second piston rod has a longitudinal axis that is parallel to a longitudinal axis of the first piston rod. The second piston rod extends through the bonnet into a second operator housing and is coupled to a second piston that is disposed within the second operator housing.

Abstract: A blowout preventer operator locking system comprises a piston rod having one end coupled to a closure member. The operator further comprises an operator housing having one end coupled to a bonnet and a second end coupled to a head. The piston rod extends through the bonnet into the operator housing where it is coupled to a piston that is disposed within the operator housing. The piston comprises a body and a flange. A sleeve is slidingly disposed within a cavity disposed within the piston and is rotationally fixed relative to the piston. A lock rod is rotatably coupled to the head and is threadedly engaged with the sleeve so that rotation of the lock rod axially translates the sleeve relative to the piston.

Abstract: A blowout preventer operator locking system comprises a piston rod having one end coupled to a closure member. The operator further comprises an operator housing having one end coupled to a bonnet and a second end coupled to a head. The piston rod extends through the bonnet onto the operator housing where it is coupled to a piston that is disposed within the operator housing. The piston comprises a body and a flange. A sleeve is slidingly disposed within a cavity disposed within the piston and is rotationally fixed relative to the piston. A lock rod is rotatably coupled to the head and is threadedly engaged with the sleeve so that rotation of the lock rod axially translates the sleeve relative to the piston.
