... Abstract Heave plates which are widely attached at the base of columns of offshore floating wind turbines (OFWTs) can effectively reduce the resonance oscillations and improve the stability of OFWTs by providing additional added mass and damping. These hydrodynamic forces are strongly affected...

... Abstract The effect of hydroelasticity on local structural response due to measured wave impact loads are discussed. The structure considered are the vertical beams at the upper flare of a SEVAN SSP FPSO. The first method uses a modal method with uniform and constant added mass. The accuracy...

... Abstract This study delves into the intricate realm of forced oscillation Computational Fluid Dynamics (CFD) simulations, placing a particular emphasis on evaluating the added mass and damping characteristics of the SWACH floating wind platform. Specifically designed by Sevan SSP and featuring...

... coefficients. To guide the proper selection of these coefficients and potentially develop a new functionality within OpenFAST that automatically prescribes and/or adjusts the heave-plate hydrodynamic coefficients, we review past literature to examine the dependence of the added mass, damping, and drag...

... that the reduced kinetic energy is absorbed by the work of contact crushing stress. The added mass used at the first stage of Popov approach is estimated with simplified empirical formulas. This paper attempts to introduce an improved method for the prediction of ice loads by accounting for the influence...

The study confirmed reduction effects due to the moonpools on motion responses comparing with a conventional pontoon with identical displacement. FOWT moonpool VAWT motion response wave exciting force added mass wave damping...

... exciting forces on the cylinder as well as the added mass and radiation damping due to the cylinder oscillation are calculated. The analytical solutions converge very rapidly with the increasing truncated number of multipoles. Calculation examples are presented to examine the effects of different...

... Heave plates are installed in Spar platforms to improve the heave motion performance of the platforms. The heave plates not only increase the equivalent added mass of the platform but also provide extra damping to the system. This article presents an experimental study on the hydrodynamic...

... equation is done, using the weighted summation of the product of the beam modes. The accuracy of the frequencies is compared with those from FEA studies. The radiation pressure on the bottom side of the plate is included to reduce the frequencies by the added-mass effect. The plate is then subjected...

...-submersible are calculated for free vibration in air. The fundamental frequency was 1.9 Hz for the beam element model and 1.5 Hz for the shell element model. When weights corresponding to a submerged structure in operation mode are considered, including the effects of added mass, the fundamental frequency...

... Navier Stokes Equations (RANSE). The free surface is modelled by a Volume of Fluid (VOF) approach. The results in this paper show a good agreement between experimental results and numerical results of both methods for aircushion pressure variations, added mass, damping and wave elevations inside...

First and second order results are presented and conclusions are drawn regarding the robustness of these codes. Diffraction Radiation Shallow Water LNG Carrier Added mass Radiation...

... 04 03 2009 Vortex Induced Vibrations (VIV) of elastically mounted rigid cylinders, with low mass-damping parameter values, are strongly dependent on the added mass coefficient. This paper aims to contribute to the technical literature by presenting some results from experiments carried...

... 05 01 2009 In simulation of 1 st -order wave-induced motion of vessels it is sometimes necessary to express frequency-dependent added mass and damping in time-domain formulation. One way to do this is to transform the frequency dependence into retardation functions. During simulation...
