To investigate the wave- and current-induced seabed response near a fully buried subsea pipeline, two-dimensional coupled model for fluid-seabed-pipeline interaction (FSPI-2D) is developed within framework of COMSOL multiphysics. Different from previous studies, both wave-current nonlinear pipeline-soil contacts are considered in present model. In this paper, Biot’s consolidation mode used to g...

The complexity of corrosion mechanisms in harsh offshore environments poses safety and integrity challenges to oil gas operations. Exploring the unstable interactions complex required an advanced probabilistic model. current study presents development a approach for consequence-based assessment subsea pipelines exposed mechanisms. Bayesian Probabilistic Network (BPN) is applied structurally lea...
