    Abstract: The disclosure provides a subsea overload release system and method. The disclosure provides a releasable connection system than can be overridden during an overload condition, and is resettable in a subsea location in situ. During normal operation, a collet sleeve is slidably engageable with a collet having one or more fingers that can releasably couple a first member with a second member. During an overload condition, an overload piston acting on fluid in an overload reservoir causes an overload pressure and a rupture or other release of fluid through an overload pressure member, causing the overload reservoir to at least partially collapse. The collapse allows the system to extend and force open the fingers to disengage the second member from the first member. When the overload symptom is rectified, the overload reservoir can be reset and the overload pressure member reset or replaced without requiring repairs above sea surface.

  • Publication number: 20030080551
    Abstract: A breakaway device joins a portion of a dispensing hose that is connected to a fueling station with a portion of a dispensing hose that is joined to a coupling that connects to a vehicle during fueling. The breakaway device includes a pair of leg members that are joined by their proximal ends to the dispensing hose portions. The distal ends of the leg members are joined at an angle to a frangible member that includes a pair of inner segments that are joined in an abutting fashion by a surrounding frangible sleeve. When a driveaway occurs, the leg members are pulled apart and exert a bending moment on the frangible member. As a result, the frangible member breaks which prevents significant damage to the station. A pneumatic line that provides pressurized air to open the station dispensing valve is attached to each leg member so that when the frangible member breaks, the pneumatic line is ruptured so that pressurized air is no longer delivered to the dispensing valve.

  • Patent number: 6457896
    Abstract: A breakaway coupling having a loop for receiving a connecting element. The loop includes a material reduction region. The material reduction region is formed as part of the loop such that the loop breaks at that region when placed under a pre-defined load. The coupling may be of fixed or swivel configuration. The material reduction region has dimensions less than the remainder of the loop such that-when the selected load is reached, the loop will break in that region. This design is particularly suited for those conditions when an underwater connecting element, such as a rope tied between an underwater lobster trap and a floating buoy, comes in contact with a marine animal. If the animal is of sufficient size, such as a whale, to apply the selected load to loop breakage, the connecting element will be released and the possibility of entanglement with the marine animal will be substantially reduced.

  • Patent number: 6450541
    Abstract: A releasable connector connects between coiled tubing, a pipe string or similar tubular string and a tool/piece of equipment. Two sleeve-shaped inter-connectable parts are configured to be releasable, wherein one is connected to the coiled tubing, and the other is connected to the tool/equipment. A locking device holds the two sleeve-shaped parts of the connector in a blocked non-released position, and a retaining sleeve keeps the locking device in its locking position. The retaining sleeve is axially displaceable for releasing the connector by a sufficient, axial displacing movement. A coaxial displaceable piston body with a transversal end surface can be influenced by fluid pressure in order to start a releasing process. The piston body has a spring, which resists the displacement of the piston and is arranged in a spring chamber. In an initial position of the connector, the spring chamber is filled with a medium which can be forced out through a cavity and an opening.

  • Patent number: 6161872
    Abstract: A breakaway system for a compressed natural gas fueling hose. The system includes an upper ring that surrounds the fueling hose. A lower portion includes three concentric disks that are arranged as a gimbals. An outer disk is coupled to the upper ring with three rods. The lower portion surrounds a male connector. A female connector, generally of the type known a quick-release connector, is coupled to the fueling hose. When the female connector is connected to the male connector, an outer sleeve of the female connector engages the inner disk of the gimbals. When a lateral force is exerted by the hose against the upper ring, the rods cause at least the outer ring to tilt relative to the male connector. Because of the gimbals arrangement, the inner disk always remains substantially flat and thus exerts a force against the sleeve thereby disconnecting the female connector from the male connector.
