Abstract: A packer assembly for an annular blowout preventer (BOP) includes an elastomeric sealing packer and multiple inserts that support the elastomeric sealing packer. Each insert of the multiple inserts includes an upper member and an intermediate member that are rotatably coupled to one another. For example, the upper member and the intermediate member are rotatably coupled to one another via a pin.

Abstract: A pressure control system includes a housing having a bore and a first pair of opposed rams positioned within the housing. The first pair of opposed rams is configured to move between a retracted position and an extended position relative to the bore. The pressure control system further includes a rotating control device (RCD) seal assembly, which includes a frame that is configured to couple to the first pair of opposed rams while the first pair of opposed rams are in the extended position relative to the bore, an annular seal element coupled to the frame, and a bearing assembly positioned between the annular seal element and the frame. The annular seal element is configured to seal about a tubular within the bore, and the bearing assembly is configured to enable the annular seal element to rotate relative to the frame and the first pair of opposed rams.

Abstract: A system includes a top drive system; a drilling riser running tool configured to be deployed by the top drive system; a fluid line configured to run from the top drive system to the drilling riser running tool; and a liquid filing system. The drilling riser running tool includes a tool head module configured to engage and hold a first riser joint at a top end such that with the top drive system above the drilling riser running tool, the first riser joint can be lowered towards a second riser joint being held near a drill floor. The first riser joint includes a central tube and a first auxiliary line. The liquid filling system is configured to provide liquid filling of the first auxiliary line via the fluid line after connection of the first and second riser joints and while the first and second riser joints are being run.

Abstract: A drilling riser cable management system includes a plurality of clamping mechanisms pre-installed on riser joints and a robotic arm. The robotic arm has a cable handling mechanism that is configured to securely install the cable on each clamping mechanism without relying on human manipulation of the cable during installation.

Abstract: An assembly for a blowout preventer includes a ram having a threaded opening. The assembly also includes a threaded shaft to engage the threaded opening and a motor to drive rotation of the threaded shaft. Rotation of the threaded shaft causes the ram to move axially along the threaded shaft.

Abstract: A drilling riser running system includes a water filling system and a pressure testing system that can fill and pressure test auxiliary lines of the riser system, while simultaneously running a riser joint.

Abstract: An inflatable packer system for an annular blowout preventer (BOP) includes an inflatable bladder configured to be positioned within a housing of the annular BOP and to inflate upon receipt of a fluid within the inflatable bladder. The inflatable bladder may be an annular structure that is configured to circumferentially surround a bore of the annular BOP.

Abstract: A system includes one or more processors configured to provide one or more control signals to cause supply of electric power from a power supply to one or more electric actuators. The one or more electric actuators are configured to adjust one or more components of a cable pressure control equipment (PCE) stack.

Abstract: A BOP includes a housing defining a bore, a first cavity intersecting the bore and comprising a first central axis, and a second cavity intersecting the bore and comprising a second central axis. The first central axis and the second central axis are non-parallel and the first cavity and the second cavity partially overlap along a vertical axis of the BOP.

Abstract: Sealing assemblies with rolling annular seals are provided. In one embodiment, an apparatus includes a stuffing box having a rolling seal positioned in a body for sealing against a tubing or wireline cable received in a bore of the body. The rolling seal can rotate within the body to roll along the tubing or wireline cable in response to movement of the tubing or wireline cable through the body and friction between the rolling seal and the tubing or wireline cable. Additional systems, devices, and methods are also disclosed.
