Patent number: 8869901Abstract: The offshore drilling system comprises a floating drilling vessel 1, a well drilled in the sea bottom 2, a tubular riser extending the well up to the floating vessel, well sealing elements fastened to the end of the riser at the level of floating vessel 1. The riser comprises tubular elements 12 connected to one another by connectors 13 designed to withstand the internal pressure of the well. Tubulars 12 comprise a metallic tubular body hooped by windings of fibers coated with a polymer matrix. The riser comprises several sections, each section consisting of tube elements whose hoop stress is determined as a function of the depth at which the section lies and of the mechanical strength of said metallic tubular body.Type: GrantFiled: July 15, 2004Date of Patent: October 28, 2014Assignee: IFP Energies NouvellesInventor: Jean Guesnon

Patent number: 7630866Abstract: The present invention relates to a method of dimensioning a riser assembly (1) intended for offshore drilling, connecting an underwater wellhead (2) to a floating support (7) comprising a main pipe (8), wherein the following stages are carried out: selecting a complete architecture for the riser assembly from specifications, notably by fixing the thickness of the main pipe and of the buoyancy means, and calculating the apparent weight of this assembly, determining the tension margin at the top of the assembly, when disconnected from the wellhead, considering the apparent weight and the tension amplified at the top by the motion of the floating support from which the assembly is suspended, in cases where the tension margin corresponds to a value close to a determined value, calculating the Von-Mises stresses in all the sections of the pipe, when connected to the wellhead, in cases where the stresses are close to a criterion determined in connection with the yield limit of the material of the pipe, checkingType: GrantFiled: May 24, 2002Date of Patent: December 8, 2009Assignee: Institut Francais du PetroleInventors: Jean Guesnon, Christian Gaillard

Patent number: 6991038Abstract: The method relates to a riser comprising a main tube and auxiliary lines. Each tubular element forming the auxiliary lines is fastened at one end by a complete link with the central tube and at the other end by a link allowing a longitudinal play J with the central tube. The method provides adjustment of play J so that, on the one hand, during conventional drilling operations, the elements forming the auxiliary lines slide in relation to the central tube and, on the other hand, during show control or testing operations, the elements forming the auxiliary lines form hyperstatic assemblies with the central tube. The method thus allows to prevent buckling of the peripheral lines when they are under pressure because they work under hyperstatic conditions.Type: GrantFiled: April 22, 2003Date of Patent: January 31, 2006Assignee: Institut Francais du PetroleInventors: Jean Guesnon, Christian Gaillard
