Large deformation finite element analysis of as-laid offshore pipelines using Coupled Eulerian-Lagrangian approach for dynamic embedment and lateral displacement

Subsea pipelines playa significant role in transportation of hydrocarbon. In deep water trenching is
difficult and therefore pipelines are often laid on the seabed. However, these pipelines could be
penetrated into the seabed a fraction of its diameter during installation. Pipelines might experience
thermal expansion due to low ambient and high internal temperature during operation cycles which can
cause pipelines to expand axially and buckle laterally. The main objective of the proposed research is
to perform finite element analyses of partially embedded offshore pipelines in cohesive soil for lateral
displacement of pipelines in undrained condition using Coupled Eulerian Lagrangian (CEL) approach
with an advanced soil constitutive model.
