Abstract: A female coupler for a breakaway thread-lock quick disconnect coupling having a retainer wire positioned interiorly of an outer housing and a coupler support portion that prevents contamination of the retainer wire and a capture space formed by grooves in the outer housing and an inner housing, which may prevent degradation of performance and/or decrease the chances that the retainer wire is dislodged.

Abstract: Provided is an apparatus for connecting two sub-flow systems (e.g. airplane fuel tanks) and conveying a fluid between the two sub-systems using a pressured balanced transfer tube, particularly when there are large radial and axial movements or offsets between the sub-systems. Unlike conventional fluid transfer systems, the present apparatus allows for the pressure in the transfer tube to be balanced to internalize the pressure forces and prevent the exertion of pressure forces on the sub-systems connected to the transfer tube.

Abstract: A quick disconnect coupling for connecting together two conduits in a high pressure fluid-carrying system. The coupling includes a female part (coupler) and a male part (nipple) each provided with a flow through channel, and each provided with a cut-off valve. The nipple is designed to be inserted into the flow-through channel of the coupler to cause the two parts automatically to be firmly latched together and to be sealed to one another during a pre-mating condition, without opening cut-off valves in the nipple and coupler. This initial pre-mating action isolates any fluid contained in the two parts of the coupling from the environment. Then, an axial force applied to the outer housing of the coupler causes both the nipple and coupler valves to open to establish fluid flow through the coupling.

Abstract: Disclosed is a method and apparatus comprising a lockdown connector 20 which connects a subsea wellhead 74 to an outer conductor pipe 10 of the mudline suspension system 12 to convert a mudline suspension system to a subsea well system while providing adjustability in both the longitudinal and radial directions and providing a means by which loads imposed on the wellhead are transferred to the outermost conductor pipe.

Abstract: A method and apparatus comprising a mudline casing hanger tieback adaptor with an adjustable load ring for connecting an installed subsea wellhead on the mudline suspension system.The mudline casing hanger tieback adaptor (180) includes a mudline hanger adaptor body (182) with an adjustable load ring 184, a packoff nut (104) and packoff (102), casing pup (186), and a tieback tool (190), all of which are lowered on a running tool to be connected to an already installed subsea wellhead (80) and sealably connected to an already installed casing hanger (64) on the innermost casing of a mudline supsension system. The adjustability of the load ring compensates for any tolerance buildup in the already installed casing (32) and adjustably shouldering the load ring (184) on the wellhead (80) transfers the load imposed on the innermost tieback tool (190) and casing hanger (70) back to the wellhead (80) during the high pressure testing of the packoff seal (202) between the tieback tool (190) and casing hanger.
