20080315578Junction Part for Coaxial Pipe Elements, and a Method of Joining Together Coaxial Pipe Elements - A cylindrical junction part for joining together two elements of an assembly of at least two coaxial pipes, comprising an outer pipe containing an inner pipe defining an annular space preferably containing lagging material. The forged junction part forms two annular cavities defined by branches in a fork configuration at each end of said part serving to minimize stresses and fatigue in the join zone between two junction parts at the ends of two lengths of coaxial pipe to be joined together and between each length of pipe and each junction part at the ends thereof.12-25-2008
20090097923Device for transferring fluid between two floating supports - A device for transferring fluid between two floating supports anchored to the sea bottom, having a rigid central undersea pipe installed below the surface with its ends each being connected to respective ones of two supports via a flexible hose. The main portion of the rigid central pipe includes or co-operates with buoyancy elements such that the central pipe adopts, in a quasi-static rest state, a configuration of an arch, preferably following a curve such that the angles between the half-lines of the axes of the rigid pipe and the horizontal half-lines at each of its ends extending towards the other end present absolute values of less than 20° and the flexible hoses present lengths and curvatures such that variations in the curvatures of the flexible hoses are suitable for compensating the movements of the floating supports.04-16-2009
20090129853Part for Connecting Pipes Including an Internal Liner, a Covering Method, and a Method of Assembly - A method of covering the inside surface of a steel connection part having an empty inside volume (05-21-2009
20100230953Coaxial Pipe Element and a Method of Fabrication - The present invention relates to a method of fabricating a coaxial pipe element (09-16-2010
20100282353Coaxial Pipe Element In Which The Inner Pipe Is Under Strees, And A Method Of Fabrication - The present invention relates to a coaxial pipe element comprising an inner pipe and an outer pipe and having at each of its ends a closure of the annular space between these two pipes, in particular by means of a forging, and in which said inner pipe is subjected to traction stress.11-11-2010
20100310319Floating Support Comprising a Device for the Retention and Securing of a Subsea Pipe - A floating support including a retaining and holding device for retaining and holding a pipe suspended from a floating support of the type comprising a ship for laying a bottom-to-surface connection pipe. The retaining and holding device comprises at least a first collar releasably locked around an end forging of a pipe element together with a support part at the floating support, said support part including load transfer and a rotary joint enabling the inclination of the pipe to be guided and having an effect of automatically centering the pipe.12-09-2010
20110042094Bottom-to-surface connection installation of a rigid pipe with a flexible pipe having positive buoyancy - A bottom-to-surface connection installation of at least two undersea pipes resting on the sea bottom. The installation having a first hybrid tower having a vertical riser anchored to a first base and connected to a the undersea pipe resting on the sea bottom and having its top end connected to a first sub-surface float. A first connection pipe, preferably a flexible pipe, providing the connection between a floating support and the top end of the riser and at least one second rigid pipe rising from the sea bottom on which it rests or from a second undersea pipe resting on the sea bottom to which its bottom end is connected, the bottom end not being anchored at the first base, up to the sub-surface where its top end is connected to a second float situated substantially at the same depth as the first float and fastened to the first float by a second flexible second connection pipe, providing connection to the floating support.02-24-2011
20110083853Inertia transition pipe element, in particular for restraining a rigid undersea pipe - An inertia transition terminal pipe element having a main rigid pipe element including at one of its ends an inertia transition piece that is constituted by at least one and preferably a plurality “n” of coaxial reinforcing pipe elements placed coaxially around the main pipe element, each reinforcing pipe element presenting an inside diameter greater than the outside diameter of the main pipe element. The various main and reinforcing pipe elements each being positioned with one end situated at the same level along the axis of symmetry of the pipe elements, and each reinforcing pipe element presenting a length that is less than the height of the main pipe element. The annular gap between the various pipe elements being filled with a solid filler material. A rigid undersea pipe is also disclosed including at at least one of its ends, an inertia transition pipe element.04-14-2011
