..., different drafts, suppression elements, and the presence of risers. The results of the experiments presented here are motion amplitudes in both in-line and transverse directions, forces and added-mass coefficients, ratios of actual oscillation and natural periods, and motions in the X Y plane...

...Chih Young Liaw; Xiang Yuan Zheng Besides the commonly considered drag force, inundation due to variable water surface is another important nonlinear effect of wave loading. Quadratic and quartic approximations of the inundation drag force are derived using the least squares method. Other nonlinear...

...Alexandre N. Simos; Celso P. Pesce; Michael M. Bernitsas; Stuart B. Cohen Several models of the hydrodynamic forces acting on a ship hull in maneuvering have been developed in the last 50 years. These models make possible analysis of ship maneuverability in high and low speeds. Following Bernitsas...

... of these complex flow phenomenon. Concurrently, there have been efforts to obtain high quality experimental data for validating the computational tools. Such efforts have sought to obtain detailed flow field and wave height data in addition to conventional force data. This detailed information can be used to help...

... structural engineering petroleum industry force bending shear deformation In evaluating the storm overload reliability of offshore platforms, it is essential to be able to quantify and understand the variability of the environmental load. For platforms where wave loading dominates...

... is constructed by replacing the Morison drag force by a cubic polynomial function of the relative fluid-structure velocity, up to cubic order. A Volterra series expansion with a finite Fourier series representation is used to approximate the response of the equivalent system. Exact solutions are developed...

...S. Vishnubhotla; J. Falzarano; A. Vakakis In this work, our previously developed approach is extended to include parametric excitation. This approach makes use of a closed-form analytic solution, which is exact up to the first order of randomness and takes into account the unperturbed (no forcing...

...Irem Y. Tumer, Research Scientist,; Raul G. Longoria, Associate Professor; Kristin L. Wood, Associate Professor This paper describes a signal analysis method using the Karhunen-Loe`ve (KL) transform, and applies the method to the analysis of hydrodynamic force data collected from controlled...
