ABSTRACT

This study aims to ensure the offshore pipeline under offshore vortex shedding analysis.
Optimizations process depending on the iterative procedures requires an analysis
considering each of extreme condition on the internal and external pipe flow. The
stabilization of the offshore pipeline on sea bottom exposed to wind-generated wave and
uniform-steady current action is achieved by utilized artificial concrete weights and
sliding resistance between pipe and soil. Additionally, the vortex shedding induced
dynamical analysis and geotechnical studies are taken into consideration.
