As offshore gas production facilities are turned on and off, the pipelines connecting the facility to the reservoir expand and contract. The result may be permanent axial movement of the pipeline, which puts stress on the structural members connected to it, and which must be appropriately engineered to avoid compromising the project. One approach to mitigating this pipeline ‘walking’ is the use a pipe-clamping mattress (PCM). Over the last year, the NGCF team have studied the behaviour of PCMs for three different offshore soil types, focusing on their ability to provide high restraint against walking over the operating life of a subsea pipeline. The outcomes of this research are being used in practice, with the objective to reduce cost without compromising performance.
