DESCRIPTION:Unburied pipelines are used for the transport of product and w
 ater in deepwater hydrocarbon developments. A critical design issue is the
  accommodation of thermal loading due to expansion and contraction of the 
 pipeline with the changes in the temperature and pressure that occur durin
 g shutdown and restart cycles. A critical design parameter\, with signific
 ant uncertainty\, is the resistance to axial movement of the pipeline crea
 ted by interaction with the seabed. This gave the impetus for the present 
 study.\n\nThis study commenced with element testing using a simple interfa
 ce strength testing device developed at the Schofield Centre to cope up wi
 th the low strengths and stresses associated with the problem. A number of
  model scale tests with actual pipe sections were also conducted. The infl
 uence of a range of parameters including pipe diameter\, pipe length\, pip
 e weight\, pipe speed\, surface roughness\, cyclic loading\, pause between
  cycles\, and OCR of the clay were studied. The results are intriguing\, y
 et challenging to interpret.\n\n
