Abstract: Traditional ship design optimises the design of ship hull and propeller for calm water conditions and then applies a suitable empirical margin to account for the influence of seastate and wind on the ship resistance. An alternative approach is to understand the unsteady flowfield generated around the hull for each wave and how this impacts on the net energy requirement for propulsion.
This talk will examine the possible analysis tools both computational and experimental for investigating such a design strategy. Computational results will be presented for validation exercises run under the auspices of the International Towing Tank Conference and discussion of possible approaches to incorporating such calculations in a ship design process.
