摘要： The invention relates to elastomeric compositions containing filler particles that are predominantly two-dimensional in shape. The elastomeric compositions exhibit significantly improved thermal, chemical, and mechanical properties as compared with elastomers containing conventional fillers such as natural clay, carbon black, and carbon fiber. In addition, the elastomeric compositions of the invention exhibit improved resistance to solvent-induced swelling and to unwanted permeation of gases such as hydrogen sulfide. The invention also provides a method of forming such elastomeric compositions and methods of using such elastomeric compositions to prepare elastomeric articles with improved resistance to thermal, chemical, and mechanical stresses.

摘要： A piston rod subassembly for use in a blowout preventer operator assembly includes a piston rod having a rod threaded interface and a rod shoulder on an outer diameter of the piston rod. A preload ring has a ring threaded interface for engaging the rod threaded interface to couple the piston rod to the preload ring. A protruding end surface of the piston rod protrudes past an end face of the preload ring when the piston rod is coupled to the preload ring and the rod shoulder engages a ring shoulder of the preload ring. A piston has a pocket for receiving the preload ring. Preload ring fasteners couple the preload ring to the piston to form a piston rod connection between the piston rod and the piston, such that the protruding end surface engages an interior surface of the pocket and a preload is induced in the piston rod connection.

摘要： A control system for a subsea blowout preventer (BOP) positioned in a lower stack, the lower stack releasably engaged with a lower marine riser package (LMRP). The control system includes a surface logic solver positioned at or adjacent the surface of the sea that generates commands for operating the subsea BOP, a first subsea logic solver attached to the LMRP and in communication with the surface logic solver so that the first subsea logic solver receives the commands from the surface logic solver, and a second subsea logic solver attached to a hydraulic control unit in the lower stack. The second subsea logic solver is in hydraulic communication with the subsea BOP, and the first subsea logic solver so that the second subsea logic solver receives the commands from the first subsea logic solver and implements the commands by activating the hydraulic control unit to operate the BOP.

摘要： An apparatus for releasably connecting a bonnet to a body of a blowout preventer includes a latch plate that is mounted to the body of the blowout preventer. The latch plate has a plate profile on an outer surface of the latch plate. A clamping assembly extends through the bonnet and includes a clamping screw releasably secured to, and extending through the bonnet. A latch key is located at an inner end of the clamping screw, the latch key having a key profile shaped to mate with the plate profile and to resist relative movement between the latch key and the latch plate. The clamping assembly is moveable between an engaged position where the key profile mates with the plate profile, and a released position where the key profile is spaced apart from the plate profile.

摘要： A blowout preventer (BOP) includes a pressure driven operator that is equipped with a balancing circuit to offset pressure inside the BOP. The operator, which is used to drive a ram, includes a piston, coupled to the ram by an operator arm, and a balance arm on a side of the piston opposite the operator arm. Pressure from inside the BOP communicates to an end of the balance arm opposite the piston and exerts a force to drive the ram radially inward.
