Oil and Gas offshore pipelines, often pass through large geographical areas, from the supply point to the end-user, crossing seismic-active areas. For unburied pipelines, both seismic ground wave and permanent ground deformation can cause severe damage to pipelines, depending on the pipeline geometry and connected structures. Due to the largely non-linear nature of the problem, a finite element...
