摘要： A load limiting break away arrangement for a subsea umbilical includes telescoping inner and outer bodies. The inner body includes multiple cross-bored holes; the outer body has slotted openings on its top and bottom sides. A shearing blade is positioned at one end of a top slot of the outer body. Individual umbilical tubes pass through a bottom slot of the outer body, through individual holes in the inner body and out a top slot of the outer body for attachment to multiple quick connect couplers on an umbilical termination head of an Umbilical Termination Assembly (UTA) and of an Electro-Hydraulic Distribution Module (EHDM). Tension resistant actuation members run between the UTA and EHDM so that when a snag of an umbilical occurs, the inner and outer bodies are pulled apart and the tubes are severed one by one by the blade of the outer body.

摘要： A technique for maintaining pressure integrity within a submersible system. The system utilizes a pressure housing with an internal component, such as a valve. The internal component is actuated by an external actuator via an actuator stem. A seal region is positioned to interact with the stem, such that the interior of the pressure housing is sealed and pressure integrity is maintained upon retraction of the stem from engagement with the internal component.

摘要： An apparatus for measuring the force applied to a thin-line towed array having a towed array hose formed as part of a thin-line towed array. Coupling components divide the interior of the towed array hose into compartments. Axial tension measurement devices are located within one compartment, and bend measurement devices are located in another compartment. These measurement devices are electrically connected to a digitization and encoding module which is in turn connected to a processing device for providing measurements of the forces on the array.

摘要： A method for pretreating and re-refining used oil that requires only moderate heat and only one re-refining step. The pretreatment involves mixing the used oil with a basic solution and optionally a phase transfer catalyst. The phase transfer catalyst aids the chemical reaction which allows removal of impurities in used oil. The basic solution preferably includes more than one base. The used oil, basic solution and phase transfer catalyst are mixed under low heat. The pretreated oil is then mixed with liquid propane in a non-turbulent manner, such as by use of a globe valve or orbit valve. The mixture of used oil and liquid propane are then placed into an extraction vessel and impurities are allowed to settle out of the oil and propane mixture. Heavy fraction may be removed from the extraction vessel. Preferably, a second vessel called a settling vessel will be used to cause further settling of impurities out of the used oil. Light fraction is produced which may be re-refined to produce base oil. The heavy fraction may be used for asphalt production. The invented method and system removes interfering amounts of metals, additives and additive derivative products from used oil and produces useful base oil.

摘要： A sealing arrangement for a subsea wellhead component is provided which comprises a primary seal to prevent leakage of internal pressure from within the wellhead component and a secondary seal surrounding the primary seal to prevent entry of ambient pressure into the wellhead component. The secondary seal is adapted to permit pressure which leaks past the primary seal to also leak past the secondary seal and vent to the atmosphere to provide an indication during testing of the primary seal that the primary seal has failed.
