摘要： A valve includes a chamber and a piston positioned at least partially in the chamber. A first POLYMAGNET is coupled to a first side of the piston, and a second POLYMAGNET is positioned in the chamber and faces the first POLYMAGNET. An actuator is coupled to the second POLYMAGNET and rotates the second POLYMAGNET from a first rotational position to a second rotational position, which causes the first POLYMAGNET and the piston to move with respect to the second POLYMAGNET.

摘要： A technique facilitates deployment of equipment, e.g. an electric submersible pumping system, in a subsea production operation. According to an embodiment, a subsea tree assembly, e.g. a horizontal subsea tree assembly, comprises a spool body housing having a channel extending therethrough. A production receptacle structure is secured within the channel and provides a reduced internal profile for securing wellbore equipment. For example, the internal profile may be constructed to sealably receive a cable hanger used to support power cable by which an electric submersible pumping system may be suspended. The production receptacle structure also may be equipped with a production stab for interfacing with a tubing hanger located below the production receptacle structure.

摘要： A technique which enables construction and operation of a subsea landing string system having a system manifold or manifolds unprotected by a dielectric fluid compensated enclosure. The manifolds contain directional control valves and corresponding solenoids which are able to operate while being exposed to environmental fluids such as seawater. The ability to operate manifolds in an unprotected environment enables the manifolds to be positioned in a variety of locations along the subsea landing string system or in cooperation with the subsea landing string system. The subsea landing string system also may be a modular system in which manifolds are added or removed according to the parameters of a given operation.

摘要： A technique facilitates continued operation of a position indicator which may be used with a valve or other types of actuatable components. The technique utilizes a housing and a stem driver mounted for rotation within the housing to actuate the valve/component to a desired position. The stem driver has a threaded region which is threadably engaged with a clutch collar located in the housing. When the stem driver is rotated relative to the clutch collar, the clutch collar moves in an axial direction along the interior of the housing. The clutch collar is coupled with a bracket which moves during axial translation of the clutch collar. The clutch collar comprises a flexible portion which enables slippage of threads at the region of coupling between the clutch collar and the stem driver if movement of the bracket becomes sufficiently restricted.

摘要： A system for recirculating a portion of a liquid fraction of multiphase production fluid to a pump for enhance functionality thereof. The system includes a splitter assembly that obtains the multiphase production fluid from the pump. The splitter assembly utilizes multiple internal chambers to separate gas and liquid fractions of the fluid. A portion of the liquid fraction may then be recirculated back to the pump as indicated whereas the remainder of the liquid fraction may be recombined with the gas fraction for production.

摘要： A gasket capable of sealing against multiple sealing surfaces, comprising an inner seal ring for sealing against inner sealing surfaces, an outer seal ring for sealing against outer sealing surfaces, one or more intermediate seal rings for sealing against one or more intermediate sealing surfaces, and a connector member for connecting the inner seal ring, one or more intermediate seal rings and the outer seal ring. In some embodiments, the gasket includes a retaining feature for securing the gasket in place and a removal feature for removing the gasket. In some embodiments, the various components of the gasket (e.g., seal rings, connector members, retaining feature, etc.) are composed of different materials (e.g., metal, metal alloy, plastic, rubber, ceramic and/or glass).

摘要： A technique utilizes spatially resolved temperature measurements to infer the temperature of a subsea infrastructure. According to an embodiment, temperature data, e.g. a temperature map, is determined for the subsea infrastructure and comprises performing remote temperature measurements of water surrounding the subsea infrastructure. Additionally, a metrological scan of the subsea structure may be obtained. Furthermore, a simulation or simulations may be run for an assumed temperature profile along a surface of the subsea infrastructure. The data obtained from the remote temperature measurements, the metrological scan, and the simulation is processed to determine a temperature profile of the subsea infrastructure. This temperature profile can then be used to facilitate a variety of subsea infrastructure management decisions.
