Patent number: 8864417Abstract: Methods of reel-laying a mechanically lined pipe (MLP) are described. These include the steps of: spooling the MLP (12) onto a reel (10) in the complete or substantial absence of internal pressure above ambient pressure in the MLP; spooling off the MLP from the reel; aligning and straightening the spooled off MLP, in the complete or substantial absence of internal pressure above ambient pressure, to provide an MLP for laying; and/or the steps of: spooling the MLP (12) onto a reel (10) resulting in the formation of wrinkles in the spooled MLP; spooling off the MLP from the reel; aligning and straightening the unspooled MLP to provide an MLP for laying having wrinkles <4 mm high, removing wrinkles, if any, while performing the hydrotest which is used to check fluid tightness of the line.Type: GrantFiled: October 22, 2010Date of Patent: October 21, 2014Assignee: Technip FranceInventors: Tomasz Tkaczyk, Aurélien Pepin

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
