Patent number: 8226327Abstract: Method for laying a pipeline onto a seabed from a lay barge, the pipeline having an inner corrosion proof metallic cladding that is closely fitted with metallic contact to an outer pipe material that is less corrosion proof. The method includes reeling a section of the pipeline onto a pipe laying drum, while an overpressure of 5-25 bar is maintained within the section by a pressurized fluid inside the section, b) joining a further pipeline section to the section already reeled onto the pipe laying drum, while the pipeline is motionless without mechanical movement, as the overpressure can he relieved as long as the sections are without mechanical movement, c) applying an overpressure of 5-25 bar within the sections and the further section is reeled onto the pipe laying drum, d) and joining several sections together and reeling the joined sections onto one or several pipe laying drums by repeating step b) and c) until the predetermined pipeline length is achieved.Type: GrantFiled: November 30, 2007Date of Patent: July 24, 2012Assignee: Statoil ASAInventors: Geir Endal, Erik Levold, Håvar Ilstad

Patent number: 8152418Abstract: Embodiments provide an apparatus and methods for providing a nonlabor-intensive process for preventing backfill entering, or environmental factors eroding, a cavity formed in the ground. Preventing cavity degradation involves constructing a chemically-inflatable bag that separates two or more chemical reactants by creases and cylindrical coils formed in the chemically-inflatable bag. The creases typically act as watertight releasable seals that separate the chemical reactants while the cylindrical coils resist unintentional compromise of the releasable seals. However, the cylindrical coils are designed to give way upon the user applying an unfurling action on the chemically-inflatable bag; thus, furnishing a passageway for the chemical reactants to intermix and initiate a chemical reaction. The chemical reaction produces carbon dioxide as a by-product, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition.Type: GrantFiled: July 16, 2009Date of Patent: April 10, 2012Assignee: Stemlock, IncorporatedInventors: Sanford S. Jenkins, Thomas S. Jenkins

Patent number: 8127837Abstract: A well cellar system includes a substantially planar base, the base defining an aperture sized to receive a conductor pipe. The well cellar system also includes at least one substantially inflexible side member attached to the base, the at least one side member and the base defining a cavity. A seal between the at least one side member and the base substantially prevents the flow of fluids between the at least one side member and the base. The attachment between the base and the conductor pipe substantially prevents the flow of fluids between the base and the conductor. An additional embodiment incorporates an extension ring to minimize/eliminate runoff entering the cellar. One version of the extension ring includes a telescoping section which moves between an extended and retracted position representing its to operative positions. Yet a further embodiment provides a rain cap to reduce the amount of precipitation which enters the cellar and becomes hazardous waste.Type: GrantFiled: May 2, 2007Date of Patent: March 6, 2012Inventor: James Anthony Rose

Patent number: 8123435Abstract: A concrete revetment block having interlocking arms and sockets and an array of vegetation holes. Two arms and two sockets are formed in the block to provide interlocking capabilities with neighbor blocks of a mat. One arm of the block is constructed with a partial thickness and one socket is constructed with a partial depth, thereby providing vertical interlocking capabilities with the neighbor blocks. An array of holes is formed through the block to allow vegetation to grow therethrough. Various holes are located in the block to allow easy grasping of the block by a workman for lifting the same. The holes are formed in the core square of the block, with respective diameters related to the thickness of the block to maximize the hydraulic stability of the block.Type: GrantFiled: February 3, 2009Date of Patent: February 28, 2012Assignee: Erosion Prevention Products, LLCInventors: James R. DeShaw, Lee A. Smith

Patent number: 8123434Abstract: A concrete interlocking revetment block having a pair of arms and a pair of sockets. The arms have enlarged ends and the sockets have enlarged cavities to interlock similar blocks together and prevent lateral separation. The arms extend outwardly from respective side edges of the block, with radial axes orthogonal to each other so as to be adjacent to each other. The sockets are formed into respective side edges of the block, with radial axes orthogonal to each other so as to also be adjacent to each other. The depth of at least one socket is less than the thickness of the block. A portion of the socket is thus covered with concrete to thereby provide reinforcement between adjacent sockets of the block, and reduce incidences of breakage. At least one arm is also formed with a thickness less than the thickness of the block.Type: GrantFiled: February 3, 2009Date of Patent: February 28, 2012Assignee: Erosion Prevention Products, LLCInventor: Lee A.
