Abstract

A dynamic response of a submarine pipeline buried in sandy seabed sediments to water loading generated by harmonically oscillating water-table vertical movements is examined experimentally and numerically. A parametric study was carried out in order to investigate the influence of depth of burial and specific gravity of pipeline on a gradual upward displacement of the pipeline. An analysis of the pipeline stability potential against floatation is presented, in which all the experimental cases tested are verified.
