| According to one or more aspects of the invention an interlock device is adapted for connection within a load path of a tubular support device to lock the tubular support device in a closed position in response to detecting a load suspended from the tubular support device. The interlock device includes a first member moveably connected to a second member and a biasing mechanism operationally connected to the first member and the second member providing a load setting resisting movement of the first member and the second member relative to one another. The first and the second member may be rotationally locked with one another to transmit rotation across the interlock device to the elevator. | ||||||
| 23 | BRAKING DEVICE FOR TOOL STRINGS | EP01938367.8 | 2001-05-25 | EP1283938A1 | 2003-02-19 | LAWRENCE, Lewis; SCOTT, Brian; MARTIN, David; MAKIN, Graeme; FERGUSON, Stuart |
| An embodiment of the invention discloses a restraint mechanism (12) of a braking device (10) for location in tubing (16) such as the casing of an oil or gas well. The braking device (10) forms part of a tool string which is run into the tubing (16) on a wireline and, in the event that the wireline breaks or is severed, the braking device (10) and the associated tool string falls through the tubing. The restraint mechanism (12) includes a sensor assembly (18), and a brake mechanism (22). The sensor assembly (18) senses the uncontrolled movement and provides an appropriate output causing activation of the brake mechanism (22), bringing the braking device (10) and tool string to a controlled stop. | ||||||

| A security device placed at a wellhead over a blowout preventer valve, which can be activated to catch a cable and/or a string of pipes upon a cut event or accident, preventing the fall of the same into the well, which includes: an upper horizontal plate and lower horizontal plate, vertically aligned, each having a circular central orifice for the passing of a string of pipes and/or a cable, and a cutout on the front part thereof, located between its front edge and the circular orifice; lateral support device, located between the upper and lower plates, that connect the plates together, delimiting an aperture at the front part of the device that together with the cutouts on the upper and lower plates form a front passage toward the inside of the device; at least two clamps driven by corresponding hydraulic cylinders, which are arranged at an acute angle with the vertical axis of the device; and a movable vertical plate arranged on the front part of the device between the lateral support means, pivotally connected by one of its sides to the upper and lower plates. The movable vertical plate, in a first position, allows for the horizontal passing of a string of pipes and/or cables through the front passage to a location at the center of the device, and in a second position, the movable vertical plate blocks the front passage. In a first position the clamps allow for vertical movement of the string of pipes and or cables and in a second position the clamps block the movement of the same. | ||||||

| A string is equipped with a braking device to regulate its speed into the wellbore through an existing tubular. When the targeted amount of overlap with an existing tubular is accomplished the two tubulars are then joined together. The braking system can take many forms such as externally mounted mechanisms that are speed responsive to vary the braking force. The inside of the tubular can have trapped gas to provide buoyancy and reduce the dropping speed. The braking can be accomplished hydraulically through regulated flow through the tubular or by a combination of a hydraulic and mechanical device. The momentum of the dropped string can also be controlled with a swage device that at the appropriate location lands on a taper and wedges or fuses itself to the surrounding tubular to gain support from the surrounding tubular. | ||||||

A control panel receiving information from the processor and a closure system movable between an open condition and a closed condition. Activatable to the closed condition by the control panel in response to the object moving from the first point to the second point at speed faster than a preset value or at a velocity outside a preset range. Also included is a method of closing a tubular of a borehole. | ||||||
