| Systems for lifting drilling risers that serve as thrust collars to retain buoyancy modules on the risers and also enable the risers to be lifted using lifting lugs that are attached to the thrust collars. In one embodiment, a lifting device uses two annular ribs at the edges of a cylindrical collar, wherein the ribs have substantially constant height, but varying thickness. The thickness of each rib is greater at the position of the lifting lug, and may also be greater at its base than that its top or outermost edge. The collar may be segmented, where the segments are bolted together to assemble the device around the riser. The segments may be pre-stressed to reduce stresses during lifting. The device may include an elastomeric layer on its inner surface. | ||||||
| 62 | Rod Clamping Devices for Hanging or Pulling Rod Strings in a Wellbore | US13660590 | 2012-10-25 | US20130101380A1 | 2013-04-25 | Arnold Wollmann |
| Clamping devices for hanging or pulling wellbore rod strings each feature housing with an axial bore in which a number of clamping pieces are placed to wedge in place between the housing and rod string to perform a self-tightening action against the rod string under the weight thereof due to cooperation of beveled surfaces at the bore wall and exterior of the clamping pieces. Threaded fasteners fed through the housing wall aid in placement of the slips against the rod string. For use in pulling operations, the housing is sized for receipt in the latching mechanism of a tubing elevator for support by the same, whereby the tubing elevator can be used to pull out a stuck rod string. Some embodiments feature a circumferential gap in the housing to enable the housing to be slipped laterally onto the rod string. | ||||||

| 66 | Clamp | US11640685 | 2006-12-18 | US07891060B2 | 2011-02-22 | Ralph Barclay Ross; Bruce Andrew Murray |
| A clamp for an oil well line is disclosed, the clamp having a casing, typically a pair of wedge members defining a line receiving recess between them and wherein the wedge member are movable within a channel in the casing to move together and grip the line when axial force is applied to the line. The radially outermost faces of the wedge members are typically shaped to match the taper of the channel in the casing, and so are pressed together as they move axially down the tapered channel. One wall of the channel is typically movable to disengage from the wedge member when the gripping force is to be removed. The line-receiving recess can be in the form of an arc or a dog leg, and can be lined with a high friction material or a softer material to minimize damage to the line by the clamping force. | ||||||
| 67 | Self-tightening safety tubular clamp | US11532203 | 2006-09-15 | US07527093B2 | 2009-05-05 | Donald E. Mosing; Jeremy R. Angelle |
| A self-tightening safety tubular clamp for suspending a casing string or other tubular member within a well. In one embodiment, a base has an opening for receiving the casing string. A first gripping member and an opposing second gripping member are each adapted to frictionally engage the casing string. First and second pivot arms include parallel linkages for supporting the gripping members. Each parallel linkage is pivotally secured to the base at one pivot pair, and pivotally secured to one of the gripping members at an upper pivot pair. Frictional contact with the gripping members allows the weight of the casing string to move the pivot arms downward. As the pivot arms move downward, the gripping members move downward and inward into engagement with the casing string. The parallel linkages ensure that gripping surfaces of the gripping members remains vertical, in alignment. | ||||||
