Abstract
A rotatable mount for a blowout preventer bonnet. A slide mounting bar is slidably couples to a body of the blowout preventer. The slide mounting bar is adapted to move along an axis of a side opening of the body of the blowout preventer. A swivel is coupled to the mounting bar and to the bonnet. The swivel is adapted to enable rotation of the bonnet when the bonnet is disengaged from the body of the blowout preventer.
Claims29
A rotatable mount for a blowout preventer bonnet comprising:
- a slide mounting bar slidably coupled to a body of the blowout preventer and adapted to move along an axis of a side opening of the body of the blowout preventer;
- and
- a swivel coupled to the mounting bar and to the bonnet, the swivel adapted to enable rotation of the bonnet when disengaged from the body of the blowout preventer.
A rotatable mount for a blowout preventer bonnet comprising:
- at least one rod coupled to a body of the blowout preventer;
- a slide mounting bar slidably coupled to the at least one rod and adapted to move along an axis of a side opening of the body of the blowout preventer;
- and
- a swivel coupled to the slide mounting bar, the swivel adapted to enable rotation of the bonnet when disengaged from the body of the blowout preventer.
A method for accessing a ram cooperatively attached to a bonnet of a blowout preventer, the method comprising:
- disengaging the bonnet from a body of the blowout preventer;
- sliding the bonnet axially away from the body in a direction parallel to an axis of a side opening of the body;
- rotating the bonnet with respect to the body, the rotation occurring about a rotational axis of the bonnet that intersects an axial centerline of the bonnet;
- and
- vertically accessing the ram.
A method for accessing a ram disposed within a bonnet of a blowout preventer, the method comprising:
- slidably coupling a slide mounting bar to at least one rod coupled to a body of the blowout preventer, the slide mounting bar adapted to move along an axis of a side opening of the body of the blowout preventer;
- rotatably coupling a swivel to the slide mounting bar;
- coupling the swivel to the bonnet;
- and
- rotating the bonnet with respect to the body to enable vertical access to the ram.
A rotatable mount for a blowout preventer bonnet comprising:
- sliding means coupled to a body of the blowout preventer;
- and
- rotating means coupled to the sliding means and to the bonnet,
- wherein the sliding means enables the bonnet to slide with respect to the body along an axis of a side opening of the body, and the rotating means enables the bonnet to rotate with respect to the body, the rotation enabling vertical access to a blowout preventer ram.
