Supporting, Anchoring, Or Positioning Of Pipe Or Cable Patents (Class 405/184.4)
  • Patent number: 6413018
    Abstract: A method for supporting an underground pipeline in an excavated trench. The method involves supporting the pipeline on specially-designed support benches at spaced intervals. The benches are designed to fail when exposed to a predetermined load, which load will be placed on the benches at some point during the backfilling of the trench or when the pipeline undergoes hydrostatic testing. When the benches fail, the fill under the pipeline is compacted and thereby supports the pipeline in lieu of the support benches.

  • Patent number: 6394701
    Abstract: An apparatus which guides a cable through a conduit. The apparatus includes a guide device for receiving the cable. Passage of the cable through the guide device is permitted. Further, the guide device is automatically moved from a first position to a second position during passage of the cable into the conduit to assist in the movement of the cable along the conduit.

  • Patent number: 6367556
    Abstract: A novel multiple configuration hand assembly centralizer system adaptable to virtually all known rock and soil anchoring applications is presented. The primary components to the centralizer include a plurality of straps and two collars which hold the straps in place utilizing a unique locking mechanism. Most preferably the standardized parts will be made from a petroleum based material. The straps are easily and manually inserted into slots in each of the collars. Each collar may be molded to provide slots for three or more straps. The collars are molded with grout passages between slots thereby allowing more than the required amount of grout to be fed through the centralizer. On a multiple configuration centralizer system, a housing assembly and retainer clip are used to frictionally hold the straps at user defined intervals on a standard zip tie.

  • Patent number: 6345933
    Abstract: An underground storage tank with backfill deflectors is provided to permit installation of the storage tank underground without requiring any workers to enter the excavation. The backfill deflectors are preferably elongate, and generally the same length as or longer than the storage tanks with which they are used and are installed on the bottom of the excavation on either side of the tank. The deflectors have walls which are sloped or inclined in a direction which tends to direct backfill dumped thereon underneath the storage tank. Desirably, the deflectors direct the backfill under the tank without requiring any of the workers to enter the excavation to shovel the backfill underneath the lower portion or haunches of the tank. After a sufficient level of backfill is introduced into the excavation and directed under the tank by the deflectors, the backfill is vibrated to achieve a compacted backfill under the tank which is sufficient to support the tank.

  • Patent number: 6340271
    Abstract: A conduit cable feeding sheave assembly is disclosed having a frame structure, an axle assembly disposed within the frame structure, and a sheave wheel disposed about the axle assembly. In one embodiment, the sheave wheel is fabricated of a self-lubricating, durable polymeric material. A slotted, tubular arm affixed to the frame extends along a line substantially tangential to the wheel. The arm has an exterior diameter sized to fit within a conventional conduit pipe, preferably having a diameter ranging from 2 to 10 inches. In one preferred embodiment, the tubular arm has at least one locking mechanism for temporarily securing the conduit sheave assembly within the conduit pipe. One disclosed locking mechanism is a threaded screw that extends from the interior of the tubular arm to engage the conduit.

  • Publication number: 20010041097
    Abstract: A universal catenary riser support that can be designed to accommodate all riser pipe diameters typically considered for production of offshore hydrocarbons and allows the catenary riser to exit from the vessel at any azimuth angle and at a wide range of angles from the vertical. The support structure at the keel of the offshore structure is provided with a receptacle to receive a curved riser segment. The curved riser segment is adapted to be received in the receptacle. The curved riser is also adapted to receive a vertical riser section through the offshore structure. Relative motions between the catenary riser and the offshore structure are accommodated by a tapered section of riser or flexible joint attached to the curved riser section. A removable plug may be provided in the curved riser section to prevent water from entering the catenary riser during installation in the offshore structure.
