Computation of design load and motion for floating structures navigating in waves

Analytical and numerical investigation is made of the source potential for- floating structure with forward speed in waves. A particular form is select ed for numerical applications, where the double integral of the Green funct ion is transformed into the single one and the oscillation characteristics for integrands in the specific computation domain are treated numerically. A comparison of calculated examples with published data is given and it sho ws that the numerical simulation is satisfactory and the accuracy is adequa te to engineering application.
