20090097922 | APPARATUS, SYSTEM, AND METHOD FOR CONCURRENTLY LAYING MULTIPLE PIPELINES - An apparatus, system, and method are disclosed for concurrently forming a plurality of pipelines. The apparatus includes a support chassis coupled to at least one transportation facilitation member. The transportation facilitation member facilities the movement of the support chassis along a surface. A first pipe fuser is disposed on the support chassis and is configured to fuse a first section of pipe to a first pipeline. A second pipe fuser may also be disposed on the support chassis. The second pipe fuser may be configured to independently fuse a second section of pipe to a second pipeline. The first pipe fuser fuses the first section of pipe to the first pipeline with the support chassis in a stationary position. The second pipe fuser fuses the second section of pipe to the second pipeline with the support chassis in the same stationary position. | 04-16-2009 |
20090123234 | Systems and Methods for Pipe Replacement - Systems and methods for concurrently destroying old pipes and installing new pipes in their place. An exemplary embodiment is a pipe bursting and replacement tool that includes a body and first and second connectors. The body has a shape that generally tapers from a smaller diameter at the front end to a larger diameter at the rear end. The taper need not be smoothly increasing, but may alternatively be stepped. The first connector couples the body to a pulling rod to and allows the body to be misaligned with the rod to relieve stress on the connection between the two. The second connector couples the replacement pipe to the body so that the replacement pipe can be pulled behind the body into the space previously occupied by an old pipe that is burst by the tool. | 05-14-2009 |
20090285634 | METHOD AND APPARATUS FOR MANUFACTURE OF A NON-HELICAL SUBSEA UMBILICAL - A method and apparatus to produce a non-helically wound subsea umbilical is disclosed. The apparatus to produce a non-helically wound umbilical may be portable to facilitate manufacturing of subsea umbilicals in remote locations. This apparatus is smaller and more economical to build and operate than conventional cabling machines that currently are used by many manufactures to produce helically wound subsea umbilicals. | 11-19-2009 |
20100104370 | Inner Pipe Fixation Device - The present invention relates to a fixation device for fixation of a position of an inner pipe of a double-walled pipe with respect to a pipe laying structure and/or an outer pipe of said double-walled pipe, said fixation device comprising: an inner pipe gripping device ( | 04-29-2010 |
20110188940 | METHOD FOR THE CONSTRUCTION OF A LONG PIPELINE - The invention concerns a method for the construction of a long pipeline using a mobile pipeline producing unit, the mobile unit being able to produce specific lengths of the pipeline, each specific length being a fraction of the length of the long pipeline, the method comprising placing the mobile unit at a first position at the stretch of the projected long pipeline, producing a specific length of pipeline in one direction of the projected long pipeline, producing a second specific length of pipeline in the opposite direction, moving the mobile production unit to a second position at the stretch of the projected long pipeline, producing a third specific length of pipeline in a direction of the long pipeline, producing a fourth specific length of pipeline in the opposite direction, optionally moving the mobile production unit to a further position at the stretch of the projected long pipeline, producing a further specific length of pipeline in a direction of the projected long pipeline, producing another further specific length of pipeline in the opposite direction and optionally repeating this process one or more further times, and connecting all produced specific lengths. The invention further relates to pipelines made according to the method described above and to the use of the pipelines in the transport of gas and/or liquids, especially crude oil and natural gas. | 08-04-2011 |
20120039670 | Method and system for inserting a pipe into an underground borehole - The invention relates to a method for inserting a pipe ( | 02-16-2012 |
20120093585 | PIPE-LAYING VESSEL AND METHOD OF LAYING A PIPELINE - A pipe-laying vessel ( | 04-19-2012 |
20130279989 | CLAMP ASSEMBLY FOR PIPE-LAYING VESSEL AND METHOD OF LAYING A PIPELINE - A pipe-laying vessel including a pipe-laying tower extending upwardly from the vessel, the vessel including a welding station for joining a new pipestring to an end of the pipeline held by the tower, a clamp assembly on the tower for engaging a pipestring with a lower end adjacent to the end of the pipeline held by the tower and with the pipestring extending upwardly from its lower end alongside the tower, wherein the clamp assembly includes a pipestring clamp that serves both the function of a transfer clamp for transferring the pipestring from a position alongside the tower but displaced from the pipe-laying path to a position approximately aligned with the pipe-laying path, and the function of a line-up clamp for lining up the pipestring with the end of the pipeline. | 10-24-2013 |
20140321919 | ARTICULATING BAND SAW AND METHOD - An articulating band saw apparatus provides a frame that includes a vertically extending section having upper and lower end portions. An elevator moves between the upper and lower end portions of the frame. A first hydraulic actuator is supported on the elevator for movement therewith. A first arm provides arm end portions, the first arm supported by the first hydraulic actuator. An end of the first arm supporting a second hydraulic actuator that is spaced away from the first hydraulic actuator. The second hydraulic actuator supports a second arm. An endless band type saw is mounted on the free end of the second arm generally opposite the second actuator. The band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms. In one embodiment, the band saw is a diamond wire saw. | 10-30-2014 |
20150010360 | Implementation of a Fluid Transportation Pipe with Flexible Hold - The invention relates to the implementation of a fluid transportation pipe. In order to achieve this, the pipe is equipped with a ballasting system, and, along a laying axis, the pipe, thus equipped, is immersed in a fluid having movement, such as the sea. A ballast mass of the ballasting system then substantially causes at least this ballasting system to sink. | 01-08-2015 |
20150139734 | METHOD FOR REMOVING FROM A TERRAIN A BURIED PIPE AND A CUTTING MACHINE USED FOR ACTUATING THE METHOD - A method for removing from a terrain (T) a buried longitudinal portion (P) of a substantially cylindrical pipe made of a ductile material and of a type suitable for use in oil pipelines, water pipelines, gas pipelines or the like, which method comprises steps of: digging at least an excavation (S | 05-21-2015 |
