Pipe Clamping Mattresses
Step-Change in arresting Pipeline Walking
Developed by Subcon in cooperation with Shell Global Solutions (Shell), the engineered 'pipe clamping mattress' (PCM) is used to mitigate pipeline-walking.
With rock-dumping the vast majority of load is passed straight to the seabed, but with PCMs 100% of the load is effective in mobilizing axial resistance.
The technique was first developed on Shell's Malampaya Project; as an alternative to traditional rock dumping. Shell presented a technical paper on the Malampaya PCM’s at the Houston OTC available here
