Pessoa, J., Fonseca, N. and Guedes Soares, C. (2008), “Hydrodynamic Interaction and Drift Forces on a Rectangular Barge and Modified Wigley Hull Arranged Side-by-Side”, Proceedings of the 27th International Conference on Offshore Mechanics and Arctic Engineering (OMAE´08), 15-20 June, 2008, Estoril, Portugal, ASME, New York, Paper OMAE2008- 57943
The paper studies the hydrodynamic interactions between two bodies in close proximity oscillating on the free surface due to the incident harmonic waves, inspired in the problem of offloading From a LNG floating platform to a tanker. It deals with a modified Wigley hull and a rectangular barge arranged
side by side. The numerical results include hydrodynamic coefficients, exciting forces, absolute motions, and drift forces, and they are compared with published experimental data followed by further analysis of the effects of free surface elevation between the two bodies. The calculations are carried
out with the WAMIT® code, which is based on a panel method, or boundary integral method.
