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.
Claims2
A method for operating a blowout preventer comprising:
- supplying hydraulic fluid to a first and second operator housing, wherein a piston is disposed within each operator such that supplying hydraulic fluid to the housings caused the pistons to translate axially through the housings, wherein each piston is coupled to a closure member;
- and
- synchronizing the movement of the pistons through the operator housings.
Dependencies are inferred from the claim text.
