| Abstract: | The existing Det Norske Veritas DNV Recommended Practice RP E305 for pipeline on-bottom stability is mainly based on
the pipe–soil interaction model reported by Wagner et al. in 1987, and the wake model reported by Lambrakos et al. in 1987, to calculate
the soil resistance and the hydrodynamic forces upon pipeline, respectively. Unlike the methods in the DNV Practice, in this paper, an
improved analysis method is proposed for the on-bottom stability of a submarine pipeline, which is based on the relationships between
Um/ gD 0.5 and Ws / D2 for various restraint conditions obtained by the hydrodynamic loading experiments, taking into account the
coupling effects between wave, pipeline, and sandy seabed. The analysis procedure is illustrated with a detailed flow chart. A comparison
is made between the submerged weights of pipeline predicted with the DNV Practice and those with the new method. The proposed
analysis method may provide a helpful tool for the engineering practice of pipeline on-bottom stability design. |
