Fully coupled CFD/FEA investigations to predict the wave loads on a flexible containership
Fully coupled CFD/FEA investigations to predict the wave loads on a flexible containership
Increase in computational power has resulted in employing RANS/CFD codes for research and development of marine and offshore units. These applications also include the fluid-structure interactions of large ocean going vessels which require the hydroelastic effects and their associated nonlinearities to be modelled accurately. This paper investigates the symmetric motions and wave-induced loads of a flexible S-175 containership by coupling RANS/CFD and Finite Element software. The numerical predictions of the pitch and vertical bending moment RAOs are compared against experimental measurements and other available numerical predictions. The results indicate that the present two-way coupled method can model with good overall accuracy the nonlinearities associated with the wave bending moments and also predict the 2-node component contribution to good accuracy.

Abstract
Increase in computational power has resulted in employing RANS/CFD codes for research and development of marine and offshore units. These applications also include the fluid-structure interactions of large ocean going vessels which require the hydroelastic effects and their associated nonlinearities to be modelled accurately. This paper investigates the symmetric motions and wave-induced loads of a flexible S-175 containership by coupling RANS/CFD and Finite Element software. The numerical predictions of the pitch and vertical bending moment RAOs are compared against experimental measurements and other available numerical predictions. The results indicate that the present two-way coupled method can model with good overall accuracy the nonlinearities associated with the wave bending moments and also predict the 2-node component contribution to good accuracy.
