| Abstract | A numerical model for the coupled dynamics of a small liferaft and fast rescue craft in a surface wave is presented. The equations are formulated in 2D using the methods of Kane and Levinson (1985) and solved numerically using a MATLAB® Runge-Kutta routine. It is assumed that the motion normal to the wave surface is small and can be neglected, i.e. the bodies move along the propagating wave profile. The bodies are small so that wave diffraction and reflection are negligible. A Stokes' second order wave is used and the wave forces are applied using Morison's equation for a body in accelerated flow.Wind loads are similarly modeled using drag coefficients. Comparison with model tests performed at the Institute for Ocean Technology shows good agreement. The model provides guidelines for predicting the tow loads and motions of small craft in severe sea states. |
