... consideration that influences their own design as well as riser and hull design. While relatively simple, semi-empirical programs do exist to analyze the fatigue due to vortex-induced vibrations (VIV) of isolated tubes in steady flows, none are generally available to analyze the complex fluid-structure...

.... After that, the simulation analysis was carried out using the time domain and non-linear FEM program. In this simulation analysis, three types of the drag force coefficients were selected. The experiments of the hydrodynamic forces acting on the oscillating cylinder in the steady flow were performed...

... viscosity, v. If the fluid motion is sinusoidal it may be completely characterized by the amplitude, a, and period, T. Thus, the instantaneous force per unit length of cylinder can be expressed as (Available in full paper) inertia coefficient oscillation steady flow drag coefficient experiment...

... obtained from tests in steady flow are not applicable to harmonic flows even when the fluid loading is predominantly drag. INTRODUCTI ON Of the scores of papers dealing with fluid loading on offshore structures none seems to have treated the effect of roughness on the force-transfer coefficients. Yet...
