Abstract
As the offshore oil and gas industry moves towards deeper ocean environments, submarine structures such as oil and gas pipelines become increasingly exposed to less understood hazards, among them gravity and turbidity currents. Our incomplete understanding of the interaction between gravity currents and submarine structures has motivated several recent experimental [1, 2] and numerical [3, 4, 5, 6, 7] investigations. Whereas previous studies focus on the force exerted on submerged cylinders and on the two-dimensional dynamics of the interaction, the current investigation places emphasis on the magnitude of the wall shear stresses near the cylinder calculated from threedimensional simulations. This shear stress is related to the process of scour near submarine structures [8].
