Stability of Unburied Pipelines. Bibliographic Study

The integrity of an unburied subsea pipeline depends to a very large extent on its stability on the seabed along its entire length. Hence the determination of this stability is of great importance in the engineering design of pipelines. This article proposes to examine the principal problems raised by the stability of unburied pipelines in the field of soil mechanics. These problems mainly concern the reactions of the soil to pipelines and their assessment, i. e. the forces of soil resistance appearing jointly with the forces exerted by the marine environment, in the equilibrium equations for such pipelines and hence also in the conventional conditions expressing their lateral, vertical and lengthwise stability.
