    Abstract: The present application provides an underwater-wellhead feeding tool assembly and a use method thereof. The device controls a controller to add pressure to an inside of a drive cylinder through a first pipeline via a first port, and to add pressure to a cavity apace between a pressure-bearing cylinder and the drive cylinder through a first branch line; the controller controls, through a third branch line, the drive device to transmit a torque to the underwater wellhead feeding tool, and transmit, through a second branch line, an axial force to the underwater wellhead feeding tool; and then a sensing component transmits a detected stress signal and/or strain signal to a data acquisition device through a test lead, thereby testing and analyzing an effect of different force field conditions on mechanical behaviors and performance of the underwater wellhead feeding tool.

    Abstract: Fluid containing contaminants may be filtered using a hydraulic control line filter for subsea high-pressure application comprising a housing, an end cap disposed at a first end of the housing where the end cap defines a filter fluid connector which comprises a fluid inlet and a filtered fluid outlet, a first centralizer disposed within the housing, a sump tube disposed within the housing and centralized within the first centralizer where an outside diameter of the sump tube and an inside diameter of the housing define a sump volume annulus there-between, a filter centralizer, and a fluid filter disposed in the housing and centralized within the sump tube by the filter centralizer.

    Abstract: A subsea production system may include a subsea tree that includes a first valve to control a flow of reservoir fluid through the subsea tree and a second valve to control the flow of the reservoir fluid through the subsea tree. The subsea production system may also include a bus system having multiple control modules that generate control signals to operate the first valve and the second valve. The bus system may also include a first electric bus that provides the control signals from a first control module to the first valve, a second electric bus that provides the control signals from a second control module to the second valve, and a third electric bus that provides the control signals from a third control module to the first valve and the second valve.

    Abstract: An accumulator system includes a chamber configured to receive a first fluid, a piston configured to move within the chamber to pressurize and drive the first fluid out of the chamber, a driving shaft coupled to the piston, a screw adapter coupled to the driving shaft, a plurality of anti-rotation shafts, and an electric actuator configured to couple to the screw adapter and to rotate the screw adapter to axially move the driving shaft. The piston includes a body defining a first aperture and a plurality of counterbores. The driving shaft is coupled to the piston via the first aperture. The piston is configured to slide over the plurality of anti-rotation shafts via the plurality of counterbores.
