  • Patent number: 6776559
    Abstract: A method of deploying a communications cable below the surface of the body of water includes loading the cable around a reel within a housing, lowering the housing and the reel into the body of water, retrieving the connector of the cable from the housing, moving the connector and the attached cable to a position away from the housing, and connecting the connector to a subsea communications connection. An umbilical line is extended over a crane structure extending over the side of an offshore structure. The umbilical line is electronically connected to the communications cable. A remotely operated vehicle or a diver will intercept the connector and deliver the connector to the subsea communications connection.

  • Patent number: 6755593
    Abstract: An impactor for use with a directional boring machine having a drill string connectable to the impactor for pulling the impactor through an existing pipeline uses rotation of the drill string to drive an internal striker. The internal striker delivers impacts in the pulling direction to an impactor housing as the impactor housing tows a replacement pipe behind it. The impactor housing is free to move axially in response to impacts from the striker over a limited distance in the pulling direction independently of the replacement pipe and drill string.

  • Publication number: 20040115004
    Abstract: A longitudinal plastically deformable wedge is used to secure a fiber optic cable or other elongate member in a groove or channel cut in a paved roadway or similar solid surface. The wedge is extruded and has arms extending upwardly from a base forming an upwardly facing slot into which a fiber optic cable or other elongate member can be inserted after the wedge is positioned in the groove. The subsequently inserted, elongate member causes outward plastic deformation of the wedge. Ribs or barbs are provided along the sides of the arms to also grip the groove walls and provide additional retention. Longitudinally extending ducts can either contain fiber optic cable when the device is first inserted into the groove or cables can be subsequently inserted into these ducts.

  • Patent number: 6742964
    Abstract: A method for installing conduits on a mountain is provided. The method includes placing at least one cable longitudinally across a ridge of the mountain and installing the at least one cable on a front side and a back side of the mountain. The front and back sides of the mountain are bounded by the ridge, and the at least one cable crosses over the ridge. The cable is positioned along both the front side and the back side of the mountain. At least one conduit is moored to the at least one cable on the front side of the mountain, and at least one cable is anchored on the back side of the mountain.

  • Patent number: 6736156
    Abstract: A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling nipple attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first drilling nipple by using a first manipulator located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism, until a second drilling nipple is reached. The translating member is attached to a fiber optic conduit. The duct rod and fiber optic conduit are then pulled back or pulled forward through the pressurized gas pipeline by the driving mechanism. A conduit is installed in a gas service line, to line the cable or conduit in a natural gas main pipeline to a telecommunications panel in a building.

  • Patent number: 6729802
    Abstract: A method of abandoning a pipeline (2) being laid by a vessel having an A/R system, wherein a sealine (2, 11, 13) is initially held by a pipe laying and tensioning arrangement. The method includes a step of reducing tension at sea level of the sealine (2, 11, 13), by connecting one or more buoyant members (13) to the end of the pipeline (2). The members (13) are then lowered into the sea, using a line (16). At least one member (13) is connected to the pipeline (2) through a connection (12) which allows pivoting of the member (13) so that the end of the member (13) at the end of the pipeline (2) projects upwardly from the seabed (3).

  • Patent number: 6715962
    Abstract: A method for assembling and delivering a drivepipe to a drill site. The method has the following steps: The drivepipe is assembled at a shoreline assembly station. Floatation devices are attached to the drivepipe and the drivepipe is floated in the ocean. The drivepipe is towed with tow vessels to a drill site. The drivepipe is delivered in a horizontal orientation to a drilling vessel at the drill site. An upper end of the drivepipe is attached to the drilling vessel and the tow vessels are detached from the drivepipe. The drivepipe is pivoted about its point of attachment to the drilling vessel until the drivepipe is vertically oriented. The buoyancy function of the floatation devices attached to the drivepipe is deactivated. The floatation devices are removed from the drivepipe. The drivepipe is equipped with a driving mechanism and the drivepipe is lowered with a running string from the drilling vessel to the sea bed.

  • Patent number: 6691734
    Abstract: A method, system and tools for introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first fitting attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first fitting by using a first manipulator located in the first air lock housing. The translating member, such as a duct rod, is advanced within the pressurized gas pipeline by a driving mechanism until a second drilling fitting is reached. The translating member is attached to a fiber optic conduit or cable. The duct rod and fiber optic conduit are then pulled back through the pressurized gas pipeline. Extractor tools extending through seals in the pressure lock housing engage with and withdraw the duct rod. Alternatively, first and second duct rods may be pushed towards each other from the first and second fittings. End elements on the duct rods engage each other.
