... Abstract This paper portrays salient features of the rock-berm pipe seabed interaction affecting the through-life axial restraint of rock berms installed intermittently over High Temperature High Pressure (HTHP) pipelines including: ( i ) axial displacement cycles of a pipeline leading...

... Abstract Rock berms are used to restrain flowlines from moving axially by adding vertical load to enhance resistance. Should the contact pressure be reduced at the flowline-berm interface, such as in response to ‘arching’ of the rock berm due to pipe settlement, this resistance may...

... Abstract Rock berms are used for many different offshore pipeline applications such as protection from anchors and trawlers, mitigation against pipeline global buckling and improvement of pipelines on-bottom stability. Understanding the lateral resistance provided by rock berms to pipelines...
