Publication number: 20160312930Abstract: A tubular assembly (10) for conveying corrosive fluid including a first iron-based tubular (12) having a cladded inner surface (14); and a second iron-based tubular (16) having a cladded inner surface (18). The first tubular (12) is connected to the second tubular (16) using a non-iron based bonding material (20). The tubular assembly (10) includes a first cladding (22) including a corrosion resistant material along the inner surface (14) of the first iron-based tubular (12) and a second cladding (24) including a corrosion resistant material along the inner surface (14) of the first iron-based tubular (12); the second cladding (24) being adjacent the first cladding (22) and proximate an end (38) of the first iron-based tubular (12) connected to the second iron-based tubular (16) by the non-iron based bonding material (20).Type: ApplicationFiled: December 11, 2014Publication date: October 27, 2016Inventors: Javad SAFARI, John HAMILTON, Sylvain DENNIEL

Patent number: 8905675Abstract: A method of manufacturing a mechanically lined pipe (MLP) having an outer pipe and an inner liner comprising at least the steps of: (a) forming the outer pipe as a single length; (b) forming an inner liner former being wholly or substantially the same length as the outer pipe of step (a); (c) locating the inner liner former of step (b) within the outer pipe; and (d) expanding the inner liner former within the outer pipe to form the MLP.Type: GrantFiled: December 8, 2010Date of Patent: December 9, 2014Assignee: Technip FranceInventors: Daniel Bertaso, John Hamilton, Sylvain Denniel, Brett Howard, Tomasz Tkaczyk, Aurélien Pepin

Patent number: 8573888Abstract: An apparatus and method for mounting a buoyancy module onto a rigid pipe having a clamp. In one embodiment the clamp includes pads for clamping onto the outer surface or coating of the rigid pip, the pads having a teeth or serrations formed thereon for gripping the outer surface of the pipe. In a second embodiment, the clamp includes one or more coil springs formed from a resilient material adapted to be wound around the outer circumference of the pipe. The method for mounting a buoyancy module onto a rigid pipe includes the steps of reducing the outer diameter of the pipe at a location of the pipe to which a buoyancy module is to be attached and subsequently mounting a buoyancy module at such location.Type: GrantFiled: June 28, 2007Date of Patent: November 5, 2013Assignee: Technip France SAInventors: Sylvain Denniel, Richard Alan Leslie Ross

Publication number: 20130195557Abstract: A method of manufacturing a mechanically lined pipe (MLP) having an outer pipe and an inner liner comprising at least the steps of: (a) forming the outer pipe as a single length; (b) forming an inner liner former being wholly or substantially the same length as the outer pipe of step (a); (c) locating the inner liner former of step (b) within the outer pipe; and (d) expanding the inner liner former within the outer pipe to form the MLP. In this way, the conventional need to overcome problems with welding a number of pre-formed 12 m or 24 m bi-metallic pipe stalks to form a 1 km bi-metallic pipe are avoided, thus also avoiding weaknesses that can be a part of conventional stalk-welding processes for forming an MLP.Type: ApplicationFiled: December 8, 2010Publication date: August 1, 2013Inventors: Daniel Bertaso, John Hamilton, Sylvain Denniel, Brett Howard, Tomasz Tkaczyk, Aurélien Pepin

Publication number: 20130108251Abstract: A pipeline for use in the offshore production of hydrocarbons comprising: (i) an electrically conductive inner pipe, (ii) a concentric outer layer, (iii) one or more concentric intermediate layers between the inner pipe and the outer layer, and (iv) a concentric electrically conductive mesh. A simple and usually thin mesh allows electric heating along the inner pipe with easy manufacture, and therefore significantly increases the simplicity and efficiency of the electrical heating of the pipeline.Type: ApplicationFiled: April 26, 2011Publication date: May 2, 2013Applicant: TECHNIP FRANCEInventor: Sylvain Denniel

Patent number: 8342248Abstract: An apparatus for venting an annular space between a liner and a pipeline of a subsea riser used for conveying hydrocarbons, the apparatus comprising a permeate recovery device for recovering permeate passing through the liner into the annular space. The permeate recovery device includes a first vent port in a wall of the pipeline at or adjacent a lower region of the pipeline and communicating with a permeate recovery line defining a flow path between the annular space and a permeate collection vessel. A one-way valve is associated with the permeate recovery line for preventing flow from the permeate recovery line into the annular space. A gaseous permeate recovery line connected to a second vent port at an upper region of the pipeline defining a flow of gaseous permeate from the annular space.Type: GrantFiled: February 8, 2008Date of Patent: January 1, 2013Assignee: Technip France SAInventors: Scott Hall, Sylvain Denniel, Jeroen Remery

Patent number: 7243716Abstract: Rigid wound or reelable pipe (1) for transporting hydrocarbons having a single-walled or double-walled envelope comprising two coaxial pipes, internal (2) and external (3), respectively, separated by an annular space, comprising at least one electrical heating cable (10) capable of being subjected to an elongation of 0.5% without sustaining damage and produced, for example, in the form of a central conducting braided cable surrounded by an electrically insulating sheath. The materials comprising the cable are subjected to elastically deformation by remaining below 15% of their elastic limit and preferably below 5%.Type: GrantFiled: December 26, 2002Date of Patent: July 17, 2007Assignee: Technip FranceInventors: Sylvain Denniel, Neil Shaw Malone
