Patent number: 10358886Abstract: A load transfer profile for connection of two bodies without preloading uses a horizontal force couple instead of a vertical force couple for maximum efficiency. The load transfer profile includes a series of tapers and/or diameters that create a radial force couple separated by an axial distance. In particular, the load transfer profile includes at least a first horizontal contact and a second horizontal contact, where each contact is a landing shoulder followed by a stop shoulder or a radial protrusion. The first and second horizontal contacts are offset by the axial distance to accommodate a force-determined bending moment such that system structural fatigue capacity is optimized. A lock mechanism assists with resisting axial loads without creating preload stresses and with locking the bodies together.Type: GrantFiled: February 3, 2017Date of Patent: July 23, 2019Assignee: ONESUBSEA IP UK LIMITEDInventor: Alexander Jose Jesus Mattey

Patent number: 10316603Abstract: A technique facilitates failsafe closure of a valve used in, for example, a subsea test tree. The technique utilizes a valve combined with a cutter oriented to sever well equipment passing through an interior passage of the valve. The valve is operatively coupled with an actuation system having an actuator piston which controls cutting and valve closure. The failsafe valve and the cutter are shifted to an open position by applying pressure in a control fluid chamber to shift the actuator piston. However, the actuator piston, and thus the valve and cutter, are biased toward a closed position via pressure applied in a pressure chamber and a gas precharge chamber. The combined pressure ensures adequate force for shearing of the well equipment and closure of the valve when hydraulic control pressure is lost. In some applications, additional closing force may be selectively provided to the actuator piston.Type: GrantFiled: June 22, 2016Date of Patent: June 11, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Gary L. Rytlewski
