Abstract

Based on previously available results and the recent research within the Liquefaction around Marine Structures program this paper formulates practical guidelines for design of pipeline on-bottom stability on noncohesive seabeds. Existing methods for calculating the probability of seabed liquefaction are recommended and the requirements for site investigations are discussed. A new formula is presented for the embedment of pipelines in liquefied soils. The implications of the method presented here are somehow similar to the density guidelines used for pipeline stability in the 1960s and 1970s but this work provides a clearer scientific justification for the methods.
