    Abstract: There is described an apparatus and method for deploying a sensor array comprising a plurality of sensors (5) joined together by connection cables (6) in one or more “chains”, and connected to an input/output device (8). An input/output connection unit (7, 15) is provided on a carrier (10), and the sensors are held on or in deployment devices (14a-14e) mounted to the carrier with their connection cables (6) connected to the input/output connection unit (7, 15). The input/output device (8) may also be mounted to the carrier, and connected to the connection unit (7, 15). The carrier (10), sensors, and input/output device (8) may be delivered as a single package to the area where the sensor array is to be deployed. The sensors are then moved from the carrier to their final positions. The deployment devices (14a-14e) may be detached from the carrier and moved sequentially to the sensor positions, and a sensor may be removed from the deployment device at each sensor position.

  • Patent number: 8764344
    Abstract: A method for laying a pipe includes predisposing first and second releasable gripping devices for firmly gripping or releasing the pipe. The gripping devices are located along the longitudinal direction of the pipe. The gripping devices when activated grip and move the pipe so that only a predetermined longitudinal pipe section is received in the laying site. The gripping devices are rearranged and activated, instant by instant, so that the pipe is at all times solidly gripped by at least one gripping device. The above step is repeated until multiple longitudinal sections are housed in the laying site. A machine for laying pipe has gripping devices independently activatable for firmly gripping or releasing the pipe and also for moving the first and/or second gripping devices a predetermined number of times while gripping the pipe, for moving multiple longitudinal pipe sections into the laying site.

Debris from the cut trench is evacuated (e.g., vacuumed) from the trench as the trench is cut. The trench may be backfilled by flowing a non-shrinking composition into at least a portion of the trench and, after hardening of the non-shrinking composition, applying a topping material to a remaining portion of the trench. In one example, the non-shrinking composition is configured to rigidify within one hour of being flowed into the trench, be substantially impermeable thereafter (e.g., having a hydraulic permeability of less than 0.0000001 cm/s upon drying), and be non-compressible and non-expanding.

    Abstract: A bore hole reaming apparatus characterized by one or more cleaning devices such as bursting heads attached to a pull rod and typically having one or more mandrels attached thereto in tandem for pulling a length of pipe through a pre-bored opening using a pulling apparatus. In a typical embodiment the bore hole reaming apparatus is characterized by a pair of bursting heads mounted in spaced-apart relationship in tandem on the pull rod and fitted with one or more mandrels attached to a third bursting head. The mandrel(s) is typically secured to a fourth bursting head by a cable and the fourth bursting head is attached to a string of typically HDPE pipe to be pulled through the bore hole. The mandrel(s) straighten irregularities and clean, smooth and enlarge the bore hole to facilitate pulling the pipe string through the bore hole with minimum friction on the pipe.

  • Patent number: 7581600
    Abstract: An improved method of forming a trenchless flow line is provided. The method includes support of the boring tool at each sight relief hole using a hook extending downwardly into the hole so as to overcome the force of gravity on the tool during the pilot hole drilling step. Then, a back reaming tool is connected to the end of the boring tool, and the pipe is connected to the reaming tool, such that the reaming tool reams the pilot hole to a larger diameter ahead of the pipe, which is pulled through the hole with the reaming tool. Drilling fluid is supplied during the reaming process to form a slurry which is pushed ahead of the pipe and upwardly into the sight relief holes, as the pipe is pulled through the reamed hole.

  • Publication number: 20080044233
    Abstract: A bend-limiting conduit controls the curvature of a catenary riser extending from the seafloor as it enters the centerwell of a spar-type offshore platform through the keel of the platform. The conduit has a bore dimensioned to receive the riser, and it extends from an upper end constrained within the keel to a lower end disposed below the keel. The conduit has increasing flexibility and weight per unit length from the upper end to the lower end, which results in a lateral load being applied to the riser as it passes through the conduit, thereby causing a gentle and gradual transition in the riser from a curved configuration at the lower end of the conduit, to a straight configuration as it emerges from the upper end of the conduit.
