A system includes a hose fitting. The hose fitting includes a body, a fluid passage through the body, a first end portion, a second end portion, and a first floating seal insert. The first end portion and the second end portion are in fluid communication with the fluid passage. The first floating seal insert is disposed in the first end portion and is configured to damp one or more shockwaves having first characteristics.

System having fitting with floating seal insert

A tracking system includes a tether, a buoyant transmitter assembly coupled to a first portion of the tether, an attachment component coupled to a second portion of the tether. The attachment component is configured to couple the tracking system to an object, and the tether enables the buoyant transmitter assembly to float above the object while the object and the tracking system are submerged in a fluid.

Tethered tracking system

A system for drilling and/or producing a subsea wellbore comprises a primary BOP comprising a primary ram BOP. The secondary BOP is connectable to a subsea wellhead such that the secondary BOP is positioned between the primary BOP and the subsea well-head, in which the secondary BOP comprises a shear ram BOP.

Blowout preventer shut-in assembly of last resort

A system and method for detecting a position of a blowout preventer's closure members makes use of an indicator rod connected to a piston of the operator system and an electronic position sensor located entirely outside of a pressurized chamber of the operator system and arranged to detect a linear movement of the indicator rod.

A system and method for guiding a dropped suspended load includes a safety winch, safety buoy, and safety anchor spaced relative to one another and an offshore rig's lifting system so that the dropped load falls away from certain seabed locations and to a safe landing area. A safety winch cable runs from the safety winch to the safety buoy, and from the safety buoy to a connection to the load. The load, when in a run-away state, falls away from vertical and toward a predetermined safe landing spot on the seabed floor. The safety buoy is then used to locate the load.

A safety-harness attachment for attaching a safety harness thereto.

Safety-harness attachment

A multi-pressure flange is disclosed that includes a first set of fasteners comprising four fasteners in a first rectangular pattern for attachment in a first pressure rating and a second set of fasteners comprising four fasteners in a second rectangular pattern in which the first rectangular pattern is perpendicular to the second rectangular pattern. The second set of fasteners is selectively combinable with the first set of fasteners for attachment in a higher second pressure rating. The flange may include a recess to receive sealing component and a receptacle configured to receive a pipe fitting. Systems and methods including the multi-pressure flange are also disclosed.

Multi-pressure flange connection

A system including, a mineral extraction component, a conduit fitting coupled to the mineral extraction component, a floating seal insert disposed in the conduit fitting. The floating seal insert includes a feature configured to tune a fluid dynamic characteristic along a liquid flow path through the conduit fitting and the floating seal insert. Furthermore, the fluid dynamic characteristic can be shockwaves, flow rate, turbulence, etc.

Tunable floating seal insert

An accumulator for hydraulically actuating subsea equipment includes a hydraulic fluid chamber and a gas chamber. The hydraulic fluid chamber is in fluid communication with the subsea equipment and comprises a hydraulic piston slidably received, at least partially, within the hydraulic chamber. The gas chamber comprises a charge piston slidably received within the gas chamber, the charge piston dividing the gas chamber into a first portion and a second portion. The first portion of the gas chamber is configured to receive ambient hydrostatic pressure therein, and the second portion of the gas chamber is configured to receive precharge gas therein.

Subsea differential-area accumulator

A system including, a mineral extraction component, a conduit fitting coupled to the mineral extraction component, a floating seal insert disposed in the conduit fitting. The floating seal insert including a feature configured to tune a fluid dynamic characteristic along a liquid flow path through the conduit fitting and the floating seal insert. Furthermore, the fluid dynamic characteristic can be shockwaves, flow rate, turbulence, etc.

Systems for accessing a well bore including a BOP stack with a universal intervention interface are disclosed. In some embodiments, the system includes a BOP stack and a valve assembly. The BOP stack has a throughbore and is installable on a well such that the throughbore is in fluid communication with the well bore. The valve assembly is coupled to the BOP stack and includes a fluid flowpath in fluid communication with the BOP stack throughbore, two valves connected in series and disposed along the fluid flowpath, the valves operable to control flow through the fluid flowpath, and a ROV panel including ports accessible by a ROV for operation of the two valves.

BOP stack with a universal intervention interface

A subsea connection apparatus to allow connecting a surface blowout preventer stack and riser to a subsea wellhead is disclosed. The subsea connection apparatus uses a single cavity blowout preventer with a set of shearing blind rams. Hydraulically actuated wellhead connectors are secured to the top and bottom of the blowout preventer to allow connection to a subsea wellhead below the subsea connection apparatus and a well head hub profile on the lower end of a riser above the apparatus. A control system can operate both of the hydraulically actuated connectors and the blowout preventer independently. A frangible bore protector is disposed in the bore of the blowout preventer to protect the shearing blind rams from pipe, tools, and fluids being passed through the blowout preventer and can be sheared by the shearing blind rams along with any drill pipe in the bore.

Subsea connection apparatus for a surface blowout preventer stack

A system for drilling and/or producing a subsea wellbore comprises a primary BOP comprising a primary ram BOP. In addition, the system comprises a secondary BOP releasably connected to the primary BOP, the secondary BOP comprising a secondary ram BOP. The primary rain BOP is actuatable by a first control signal. The secondary ram BOP is actuatable by a second control signal. The secondary rain BOP is not actuatable by the first control signal.
