On-bottom stability of pipeline is a one of the key factors that affects the design and installation methodology of subsea pipelines.
Insight into Pipeline On-bottom Stability, DNV RP F and DNVGL RP – OnePetro
With ever increasing demand for energy, the need for new pipelines in harsher seabed conditions is on the rise and hence accurate on-bottom stability assessment of pipelines plays a vital role in cost effective pipeline design and ensures the long-term integrity pipelines. It is often assumed that the seabed is stable while undertaking pipeline on-bottom stability of pipelines. However, this may not be case due to seabed mobility and wave induced liquefaction, especially in sandy seabeds.
Therefore, insight into how to evaluate the seabed mobility and wave induced seabed liquefaction is provided in this paper. Results from parametric study of on-bottom stability of a typical pipeline are presented to highlight the key influence of seabed classification on the on-bottom stability assessment results.
Seabed mobility and wave induced liquefactioin results are presented in graphical form such that they can be assessed quickly for Front End Engineering Designs FEED. The results presented in this paper are a vital source of information for all pipeline design engineers.
