| 20080286050 | STAB AND HINGE-OVER PIPELINE END TERMINAL ASSEMBLY - A subsea system for securing an end portion of a pipeline includes a subsea foundation. The foundation has a lower portion located below the sea floor and an upper portion extending above the sea floor. The subsea foundation has a receptacle formed in the upper portion. The system includes a base frame that lands on the subsea foundation. The base frame has a track formed therein. A stab is hingedly mounted to the base frame. The stab stabs into the receptacle to secure the base frame to the subsea foundation. A sliding mechanism is carried by the base frame and moves along the track. The sliding mechanism is connected to a segment of the pipeline extending along the sea floor. A terminal assembly for an end portion of a pipeline and a method for securing an end portion of a pipeline are also included herein. | 11-20-2008 |
| 20080310922 | Pipeline buoyancy control assembly and tiedown - A pipeline buoyancy control assembly is operable to simultaneously retain a plurality of pipelines against buoyancy forces. Respective ends of two retaining straps corresponding to two respective pipelines engage a tie-down member of a single control assembly. The retaining straps are placed over the respective pipelines and other ends of the retaining straps are attached to additional control assemblies. Further, stresses exerted on the retaining straps when the pipelines are subjected buoyancy forces are minimized by the unique structure of the tie-down member and the manner by which the retaining straps attached thereto. | 12-18-2008 |
| 20090092447 | NON-ABRASIVE PAD FOR AN ARTICULATED SEABED MAT - A block and pad unit for use in forming a seabed mat includes a concrete block having an upper surface, a lower surface and at least four sides extending between the upper and lower surfaces. An opening extends from the upper surface to the lower surface of the block. An abrasive resistant pad is attached to one of the upper surface or the lower surface. The pad includes a base having a lower side adjacent the block and an upper side facing away from the block, an opening aligned with the opening of the block, and a plurality of dome-shaped mounds extending integrally upward from the upper side of the base and distributed about a periphery of the opening of the pad. | 04-09-2009 |
| 20090238647 | METHOD FOR COUPLING SEISMOMETERS AND SEISMIC SOURCES TO THE OCEAN FLOOR - The present invention is directed to methods for coupling seismometers and seismic sources to the ocean floor that results in improved seismic data quality and repeatability for reservoir management and seismic monitoring activities. Piles are configured with a coupling device and permanently installed on the ocean floor. The seismometers or seismic sources are acoustically coupled to the piles on the ocean floor via the coupling device. The pile, seismometer and seismic source may be surface treated with a material that releases divalent cations to enhance both the acoustic coupling and the load holding capacity of the pile. The pile is permanently imbedded into the seabed while the expensive and high-maintenance seismometers and seismic sources are redeployed on the piles as needed. | 09-24-2009 |
| 20100189514 | BALLAST-FILLED PIPELINE WEIGHT - A flexible bag-type pipeline weight, configured to straddle a pipeline, has internal tie means to prevent excessive bulging of the weight after being filled with ballasting material, thus facilitating installation in narrow trenches. Built-in loading loops facilitate filling the weight with ballasting material without need for special loading equipment. The bag-type pipeline weight is formed with a pair of leg sections on either side of a Central, pipeline-receiving recess. Once filled with ballast, the legs remain separated, thus facilitating installation on a pipeline. The filled pipeline weight is also freestanding and stable for purposes of transport and storage prior to installation. Hoisting slings facilitate lifting and manipulation of loaded pipeline weights without the need for spreader bars. | 07-29-2010 |
| 20120003048 | DEVICES AND METHOD FOR EQUIPMENT FOUNDATION IN THE SEA BED - A device is described for a foundation to be placed in a sea bed, comprising a housing-formed, downwardly open, coat-forming construction set up for placing in the sea bed, said construction comprises a top part, and the top part comprises an extended hollow body ( | 01-05-2012 |
| 20120263542 | ASSEMBLY FOR CONNECTING A FLEXIBLE TUBULAR LINE TO AN UNDERWATER INSTALLATION - An assembly for connecting a flexible line ( | 10-18-2012 |
| 20130170914 | SYSTEM AND METHODS FOR STABILIZING SUBSEA PIPELINE - Disclosed are systems and methods for stabilizing a subsea pipeline such that movements of the pipeline in the axial, lateral and/or vertical directions are restrained. The pipeline is connected to a stabilizing structure generally adjacent to the pipeline using one or more load-bearing members attached to the pipeline and the stabilizing structure at one or more predetermined locations. Also disclosed are systems and methods for monitoring operating parameters of the pipeline over time. | 07-04-2013 |
| 20140044488 | CONDUIT DISPLACEMENT MITIGATION APPARATUS, METHODS AND SYSTEMS FOR USE WITH SUBSEA CONDUITS - Disclosed are apparatus, systems and methods for reducing displacement of a subsea conduit such as offshore hydrocarbon production pipeline, also referred to as pipeline walking or buckling, thus reducing the need for expensive pipeline anchoring or other mitigation solutions. A movement resistor adapted to be installed on a subsea conduit is provided having an inner portion adapted to receive and securely attach to a subsea conduit and at least one resistor portion adapted to resist induced forces. At least one movement resistor can be installed along the length of a subsea conduit. | 02-13-2014 |
| 20140286709 | METHOD AND SYSTEM FOR SECURING A PIPELINE TO THE BED OF A BODY OF WATER - A method of securing a pipeline to the bed of a body of water includes moving an underwater vehicle selectively, on the bed of the body of water, along the pipeline; transporting a plurality of fastening devices on the underwater vehicle; and driving each fastening device partly into the bed of the body of water, close to the pipeline, by a handling device mounted on the underwater vehicle, to confine the pipeline between the bed of the body of water and the fastening device. | 09-25-2014 |
