Subterranean Or Submarine Pipe Or Cable Laying, Retrieving, Manipulating, Or Treating Patents (Class 405/154.1)
  • Patent number: 10527196
    Abstract: A subsea pipeline coated with a thermally insulating coating has a radially outer surface shaped to define external hold-back formations. In a J-lay operation, the weight load of a pipeline catenary is held back using a complementary bushing or clamp of an installation vessel engaged with the hold-back formations. The weight load is transferred from the catenary to the bushing or clamp by shear forces acting through the coating. The coating extends continuously along the pipe and is interposed between the hold-back formations and the underlying pipe. The hold-back formations may be integral with the coating.

  • Patent number: 10378688
    Abstract: A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

  • Patent number: 9694879
    Abstract: A method for determining start and stop times of at least one selected operation on a pipe deployment vessel includes measuring either or both tension on a pipe deployed from a reel on the vessel and velocity of pipe motion with respect to the vessel. Rotational velocity of the reel is measured. Geodetic position of the vessel with respect to time is measured. The start and stop times of the at least one selected operation are determined from the measured tension, motion velocity, rotational velocity and geodetic position. The start and stop times are recorded.

  • Patent number: 8657529
    Abstract: At a location where unevenness 1000 is present, the condition of a seabed 200 is investigated in advance to examine the respective numbers of large filter units 51 and small filter units 52 to be used, and the position where the large filter units 51 and the small filter units 52 are to be installed. Based on the investigation result, the small filter units 52 are installed on the bottom of the unevenness 1000. The large filter units 51 are installed on the upper surface formed by the installed small filter units 52, and are leveled so that the upper surface formed by the installed large filter units 51 becomes flush with the seabed 200.

  • Patent number: 8641323
    Abstract: A method of positioning on the sea floor, from a floating vessel, an unlaid end portion of a pipe that is being laid from its other end on the sea floor is disclosed. The method includes lowering the unlaid end portion of the pipe to a lowered position above the sea floor. Transfer of the load of the unlaid end portion of the pipe occurs from the lowering device to a line for suspending the unlaid end portion of the pipe. Lowering the line for suspending and the unlaid end portion of the pipe occurs. There is disclosed a corresponding method of recovery as well as associated apparatus. A method for effecting a subsea connection between one line and an object suspended below the surface of the sea by another line and associated apparatus are disclosed.

  • Publication number: 20140030024
    Abstract: This invention relates to an improved apparatus and component for removing (and perhaps replacing) pipes, in particular underground pipes, as suitable for use in trenchless pipe removal methods such as that of WO 2008/071997. The invention provides a component which is securable to a cable, and which has a sleeve for surrounding an end of the pipe. The component has an opening through which a settable fluid may be delivered into the pipe in use. A surface of the component is adapted to seal the end of the pipe so that the settable fluid may not leak from the pipe before it has set. The apparatus comprises the component, a cable secured to the component, a winch and a settable fluid.

  • Patent number: 8616805
    Abstract: An optical fiber management system for a remotely operated vehicle (ROV) includes a spool containing a length of optical cable, a motor coupled to the spool, a motor controller, a speed sensor and a feed mechanism. The motor controller can detect the speed of the ROV through water and control the rotational speed of the motor so that the optical cable is removed from the spool at a speed that is equal to or greater than the speed of the ROV. A feed mechanism is used to apply a tension to the optical cable so that it is removed from the spool and emitted from the ROV without becoming tangled.

  • Patent number: 8556538
    Abstract: A spool has a cylinder, a first flange coupled to a first end of the cylinder and a second flange coupled to a second end of the cylinder. A compressible material surrounds the cylinder and an optical fiber is wrapped around the compressible material. When tension is applied to the optical fiber the compressible material can be deformed to reduce the tension on the optical fiber. When submerged underwater the water pressure will not compress the compressible material.

  • Patent number: 8538225
    Abstract: A communications ducting system, and method of laying a communications duct assembly below a surface, usually in a carriageway or footpath, using an open slot which is subsequently backfilled. The width of the slot is preferably not substantially greater than the narrowest outer cross sectional width of the duct assembly. In at least one direction, the duct assembly has a dimension of less than 20 mm and thus the slot need be no more than 20 mm wide. The duct assembly can be laid along the bottom of the slot, preferably on a layer of sand or other bedding material. Access chambers may provide fiber blowing points along the slot for installing optical fiber in the duct assembly after the assembly is in place, either for the original installation of the fibers or for repair purposes. The access chambers can also be used to accommodate changes in direction of the slot and for repairs in the duct assembly.
