Abstract: A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, while the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs. Additionally, while the secondary spring is engaged, hydrodynamic damping of the ball opening movement is provided.

Abstract: A downhole drilling valve tool, positioned above the drill bit, which utilizes a ball valve having a through bore for normal flow. The ball valve is operated bidirectionally by a piston driven mechanism between an open position and a closed position. The piston mechanism is responsive to a reference accumulator pressure on a first side and the pressure in the apparatus bore above the ball valve on a second side. Whenever the valve apparatus is lowered at least a minimum distance into the well bore, a pressure relief valve is used to maintain a fixed margin between the flowing bore pressure and the accumulator pressure. Closure of the ball valve occurs when the accumulator pressure exceeds the bore pressure during pump stoppages. The downhole drilling valve tool offers a more wear resistant sealing means, as well as higher pressure operability than conventional downhole check valves.

Abstract: The present invention provides a hot tap machine having independent speed drives for the center drill and the holesaw that can be remotely operated. The hot tap machine of the present invention also has improved vibratory damping and coupon stability and retention. During operation, the machine cartridge holding the machine internal assemblies of the hot tap machine of the present invention is, except for its controls and external support systems, entirely contained within its pressure containment housing which is sealingly attached to the hot tap fitting on the pipe. An advantage in the operation of the present invention is the independence of the center drilling operation and the pipe coupon cutting operation.

Abstract: A method and apparatus for controlling fluid flow with a quarter-turn ball valve with seats operated to lift off the sealing surface of the ball valve prior to ball rotation and to reseat upon completion of the ball rotation. One embodiment shown relates to a quarter-turn ball valve having a rotatable cam with an eccentric camming disk that engages a cam pocket in the ball seats to reciprocally lift off the sealing surface of the ball valve prior to ball rotation and to reseat upon completion of the ball rotation. An embodiment is also shown that provides filler pieces that restrict that flow around the ball valve whenever the ball seats are lifted off the surface of the ball valve.

Abstract: A floating moored oilfield production structure for deepwater application. An apparatus and a method for the construction and installation of floating oilfield production structures, wherein the deck structure is supported by multiple pairs of inclined buoyant legs which in turn support a subsurface damping plate structure for reducing the motions of the platform. The structure initially is initially constructed in a first configuration in relatively shallow water and then towed to a deepwater location where it is reconfigured to its operational configuration. The major structural components are joined by selectably operable pin connections.
