For two decades the mechanically lined pipe has been applied as onshore and offshore pipeline in the oil and gas transportation. Up to now more than 1,000 kilometres of this kind of linepipes have been installed. In the past the main offshore installation methods for mechanically lined pipes were S-lay, Jlay or Bundle. The objective was to produce a reelable mechanically lined pipe with dimensions of 6 up to 18” without any further procedures such as application of internal pressure or reinforcements of the liner material. Over the last years, various approaches were investigated to prepare the mechanically lined pipe for the reeling technique which is much more efficient and economic than the above mentioned installation methods.
