Abstract
Methods of reel-laying a mechanically lined pipe (MLP) are described. These include the steps of: spooling the MLP () onto a reel () 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 () onto a reel () 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. By minimizing the size of the wrinkles and/or particularly selecting the liner of the MLP, the methods of the present invention allow safer, faster spooling and spooling off to be effected to provide safer, faster and more economical laying of an MLP.
