| dc.description.abstract | The existing DnV Recommended Practice (RP E305) for pipeline on-bottom stability is mainly based on the Pipe-Soil Interaction Model proposed by Wagner et al. (1987) and the Wake Model by Lambrakos et al. (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 and 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. | en |
