Bedform evolution around a submarine pipeline and its effects on wave-induced forces under regular waves
TL;DR: In this article, an experimental investigation of seabed evolution behavior around a submarine pipeline and the hydrodynamic forces on the pipeline under regular waves was presented. And the influence of bedform evolution on wave forces was found to vary significantly in different regimes.

Wave pressures and uplift forces on and scour around submarine pipeline in clayey soil
TL;DR: In this article, the authors investigated wave-induced pressures and uplift forces on a submarine pipeline (exposed, half buried and fully buried) in clayey soil of different consistency index both in regular and random waves.

Wave force on protected submarine pipelines over porous and impermeable beds using SPH numerical model
Hassan Akbari,Ali Pooyarad +1 more
TL;DR: In this article, a numerical model based on WCSPH method is utilized to simulate wave propagation over a pipeline and a hybrid approach is introduced to absorb outgoing waves based on gradual decrease of fluid velocity in an absorbing layer and using sloping beds simultaneously.

A finite volume solution of wave forces on submarine pipelines
TL;DR: In this paper, a numerical model is established for simulating the wave forces on a submarine pipeline, where a set of two-dimensional Navier-Stokes equations is discretized numerically with a finite volume method in a moving mesh system.

Waves forces on offshore pipelines
N. Jothishankar,V. Sundar +1 more
TL;DR: In this article, the experimental results of wave forces exerted on a model pipeline, of diameter 5 cms at different clearances from the bed of the flume, were presented, along with the measured forces and their correlation with the non-dimensional parameters, Reynold's Number, Keulegan-Carpenter Number and relative clearance.

Regression Model of Wave Forces on Ocean Outfalls
TL;DR: In this paper, regression analysis is used to select a prediction equation for the determination of wave forces on circular pipes resting on a flat boundary under the action of intermediate water waves, and dimensional analysis is applied to reduce the number of independent variables from five to three so that the prediction equation will fit a range of pipe diameters, water depths, and wave heights.

Forces Exerted by Waves on a Pipeline at or Near the Ocean Bottom
TL;DR: In this paper, a modified lift force model of the form, F sub L = 1/2 C sub L RHO A u sub max sq (COs sq (theta-phi) - k), is proposed where the parameters, C sub l, Ph1 and k, may vary accordingly to allow adequate description of all characteristics of the lift force phenomenon.
