Guedes Soares, C., Fonseca, N. and Pascoal, R. (2001), “Experimental and Numerical Study of the Motions of a Turret Moored FPSO in Waves”, Proceedings of the 20th International Conference on Offshore Mechanics and Arctic Engineering (OMAE’01), 3-8 June, 2001, Rio de Janeiro, Brasil, ASME, New York, Paper OMAE2001/OFT-1071.
The paper presents the results of an experimental program carried out with a model of an FPSO (Floating Production, Storage and Offloading) unit moored and subjected to incoming waves. In regular waves, a wide range of wave lengths were tested, and the effect of the wave amplitude was also investigated. In irregular waves the model was subjected to different seastates, including very severe significant wave heights. The measured responses include the six degrees of freedom absolute motions, relative motions, and the mooring forces. The experimental data of surge, heave and pitch is compared with calculated results from a Green function panel method and a strip theory program. In general the agreement between experimental and numerical data is very good.
