Abstract
A method is disclosed for reeling a pipeline having an inner corrosion-resistant metallic liner that is tightly fitted within the pipeline. To minimize or avoid wrinkling of the liner during the reeling or unreeling, a length of the pipeline is internally pressurized by deploying a single sealing pig within the pipeline near to the trailing end of the pipeline and applying pressurized fluid within the pipeline, and then the length of pipeline is reeled onto a storage reel. In the pressurizing process, the length of the pipeline is filled with fluid at an elevated pressure within a range defined by a lower limit of 5 bar.
