Two-dimensional and three-dimensional approximate hydroelasticity theories are used to predict the dynamic response of 5- and 16-module very largefloating structures in regular waves. For the two-dimensional approach, strip theory is combined with a beam model of the structure to determine the dynamic response. However, the fluid forces from strip theory are augmented with "surge" forces calculated from Morison's equation. For the three-dimensional approach, a rigid module, flexible connector structural modelis used with fluid loading obtained with the three-dimensional double composite source distribution technique. Fluid-structure interaction effects are studied and connector moments are obtained. These approximate methods of hydroelastic analysis offer alternatives to the more computationally demanding, fully three-dimensional flexible module, flexible connector modelin which linear potential theory is used.
