Integrated Analytical and Finite Element Assessment of Stress and On-Bottom Stability for a Deepwater Offshore Pipeline in the Gulf of Guinea
Offshore subsea pipelines in the Gulf of Guinea are subjected to the combined effects of deepwater hydrostatic pressure, soft-clay seabed conditions and a high-intensity metocean environment. In this paper, an integrated analytical-numerical approach is developed for evaluating the stress and on-bottom stability of one...
