摘要： In a hydraulic subsea control system having two separate redundant subsea control pods in which each pod is supplied with a hydraulic power supply line and a plurality of fluid control lines by surface controls. The improvement in means for alternately connecting and disconnecting the fluid control lines to each pod. Coacting quick disconnect couplings having first and second portions are positioned between the surface controls and each of the sets of fluid control lines to each pod. Each coupling portion includes a valve whereby when the first and second portions are engaged the valves permit fluid flow and when they are disengaged shut off fluid flow. First and second junction plates are connected between the surface controls and the connected fluid control lines and a hydraulic cylinder and piston assembly is connected between the first and second plates for alternately connecting and disconnecting the couplings to each pod whereby the two pods are controlled separately, but redundantly. The control of the cylinder and piston assemblies is preferably provided by the hydraulic valve which alternately provides fluid power to the power supply line whereby when power is supplied to the power line of one pod the coacting couplings to that pod are connected while fluid power is disconnected from the other pod, and the coacting couplings to the other pod are disconnected.

摘要： An underwater fluid connector for interconnecting a plurality of fluid lines. A first male member or plurality of members are adapted to be positioned underwater including at least one upright position flat side with a plurality of fluid passageways terminating at said side. An inverted U-shaped retrievable female member having first and second flat interior faces and adapted to engage and disengage from the first member wherein the faces are positioned for alignment with but spaced from the first member flat side when engaged for providing a venting space therebetween and having a plurality of passageways terminating at the interior faces for axial alignment with the first member passageways. A metal valve seat is releasably connected to the first member flat sides about each of the first member passageways. A valve is positioned in each of the second member passageways having a movable element, a hydraulic supply port, and a pilot actuator connected to the valve element. In one position the valve element seats on the valve seat and opens the fluid supply port and in a second position closes the fluid supply port and is removed from the valve seat. A resilient seal is connected to the valve element and adapted to seat on the metal valve seat. The seat and seal are circular and the seat includes a circular lip having a width less than the resilient seal for providing higher unit sealing forces.

摘要： A safety apparatus for preventing the traveling block of a drilling rig from being drawn into the top of the rig and also for preventing the traveling block from falling downwardly below a predetermined bottom position. A high position limiting valve has an air inlet and an air outlet with a valve stem providing communication between the inlet and the outlet when a predetermined amount of cable is spooled onto the drum. A low position limiting valve has an air inlet and an air outlet with a stem yieldably urged at all times into engagement with the cable for actuation and providing communication between the inlet and the outlet when a predetermined amount of cable is spooled off of the drum. An air supply is connected to the inlets of the valve and the outlets of the valves supply air to stop the actuation of the cable drum. The longitudinal axis of the valves are positioned generally perpendicular to the surface of the cable drum and their stems are longitudinally movable.

摘要： A method and apparatus of compensating for the closing force on a blowout preventer caused by well pressure for reducing the wear on the blowout preventer sealing element when moving a drill string through a closed blowout preventer. A hydraulic opening force is applied to the blowout preventer which is actuated by and is proportional to the well pressure. A compensating line is connected between the blowout preventer fluid supply line and the blowout preventer opening line. A control valve is provided in the compensating lines for applying an opening force on the blowout preventer and a pilot control pressure regulator is provided in the compensating line for limiting the compensating pressure. The pilot control line is connected between the regulator and the well pressure in the blowout preventer whereby the output pressure is proportional to the well pressure for compensating for the closing force on the blowout preventer caused by the well pressure.
