Proportional electrohydraulic servo valve closed loop feedback control of pressure reducing and relieving hydraulic circuit

Systems, devices and methods for regulating pressure in a blowout preventer (bop) of a subsea well assembly. A closed loop regulator (clr) that combines the functions of a pressure relieving valve and a pressure reducing valve into one body to control the pressure of a hydraulic circuit or a bop mux control pod. ... Hydril Usa Distribution Llc

Automated reel control console

The present disclosure is to systems and methods for actuating pneumatic controls of reels electronically via a remote console, thus expanding remote control capabilities in a combination of hazardous and undesignated areas for oil and gas technologies. The method includes receiving, at a second control network from a first control network, electrical control signals for controlling pneumatic solenoids of a second control network. ... Hydril Usa Distribution Llc

Failsafe system and method for reducing load in a hydraulic cylinder

A mechanism to reduce load of a hydraulic cylinder having a body, a stem movable within the body, and a piston rod connected to the stem. The mechanism includes a mechanism body attached to the body and defining a recess, and a retainer attached to the mechanism adjacent the opening of the recess so that the retainer substantially fills the opening of the recess, and having an aperture that receives an end of the piston rod. ... Hydril Usa Distribution Llc

Blind shear ram

A system includes a blowout preventer (bop) including a shear ram assembly. The shear ram assembly includes a first shear ram block having a first forward end, a first blade having a first forward face and extending from the first shear ram block, a face bolt passage extending into the forward end of the shear ram block, a face bolt positioned within the face bolt passage configured to couple the first blade to the first shear ram block, and a first seal containment encapsulated by the first shear ram block.. ... Hydril Usa Distribution Llc

Short-chain fluorocarbon-grafted elastomer blowout preventer packers and seals for enhanced h2s resistance

A packer unit to be used in an annular blowout preventer. The packer unit includes an elastomer body including a compound of a nitrile rubber base polymer having a polymer chain, and a quantity of fluorine atoms attached to the polymer chain. ... Hydril Usa Distribution Llc

Boltless locking of bop bonnet

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. ... Hydril Usa Distribution Llc

Pump chamber position indicator

A pump with a position indicator is disclosed. The pump includes a pump housing, wherein the pump housing includes a flexible bladder disposed therein; a first fluid zone, wherein the first fluid zone is operable to allow flow of a first fluid into and out of the first fluid zone; and a second fluid zone, wherein the second fluid zone is operable to allow flow of a second fluid into and out of the second fluid zone. ...
