Dynamic Analysis of Interaction between Linear Waves and Spar Floating Platform

Spar platforms are large structures which are used in deep waters. Because of their large dimension, Morrison’s Equation is not suitable to estimate hydrodynamic forces on this kind of platforms. Therefore in this study wave forces and hydrodynamic coefficients of a spar platform have been estimated in six degree of freedom using diffraction theory. The incident wave is assumed to be harmonic and linear. Diffraction and radiation velocity potential were solved with finite difference method. The results showed that the developed model is able to estimate the wave forces and hydrodynamic coefficients on large structures considering diffraction theory with acceptable accuracy.
