PREVENTION OF UPHEAVAL BUCKLING OF HOT SUBMARINE PIPELINES BY MEANS OF INTERMITTENT ROCK DUMPING

The extraction of oil and gas from marginal reservoirs has become feasible through the development of subsea completions. As a consequence of the adoption of this technology, untreated oil and gas often at high temperatures are being transported from such completions to surface facilities by pipelines, which are therefore exposed to the effects of thermal expansion. Frictional restraint to such expansion causes built-up of high compressive forces which can in turn cause the pipeline to buckle. the paper reports on how such a potential problem was assessed and resolved in 1985.
