Introduction

The on-bottom stability (also termed as “geotechnical stability”) of submarine pipelines mainly involves vertical, lateral, and axial pipeline-seabed interactions under ocean waves and/or current and engineering operating conditions.

Vertical Stability of the Pipeline on and in Seabed

Submarine pipelines that are intended to be buried in the seabed should be checked for possible sinking or floatation in order to satisfy the vertical stability on and in the soil. For the pipelines to be laid on the seabed with low shear or cohesive strength, the bearing capacity of the soil needs to be evaluated. If the seabed soil is, or is likely to be, liquefied under pure waves or combined waves and current, the liquefaction depth should be predicted accurately. Seabed liquefaction can affect both the vertical stability, i.e., sinking and floatation, and the lateral stability of submarine pipelines (see Det Norske Veritas and Germanischer Lloyd 2017).
