... The Umverstty of Texas at Austm Austin, Texas, USA Abstract It has been recognized for some time that sinusoidal oscillatory flow experiments generate hydrodynamic force coefficients larger than those measured in a random sea environment. The present study investigates forces induced on cylinders by random...

... on a circular cylinder subjected to wave action consists of a drag as well as an inertia component. It is assumed that the total wave force per unit length on a fixed vertical cylinder of the diameter D at position r = (XI,X2,X3) at the time t can be estimated by using Morison's equation as, (Sarpkaya...

... acting on weakly buoyant pipelines under tow. Experiments have been made at a scale of about 1/13 in a wave flume, of a prototype pipeline of diameter D = 0.8 m. Unfortunately the prototype length of the test cylinder was only about 70 m and the model was therefore moving appreciably in waves, even...
