Abstract
A hullform was developed for a new frigate based on the parent hullform of an existing design. The new hullform is able to provide higher payload and stability performance, consequently increase its adaptability capability. Initial bare hull resistance to the new hullform concept was estimated using CFD (Computational Fluid Dynamics). After the final fairing, a hydrodynamic campaign was defined to measure the hydrodynamic characteristics of the new concept. BAE Systems used, for the first time, numerical prediction methods to undertake a complete hydrodynamic campaign on a hullform. The campaign included Bare Hull Resistance, Propeller Nominal Wake Survey, Self- Propulsion, Appendage Alignment, Seakeeping and Manoeuvring. The current paper is focused on the Bare Hull Resistance Analysis. A validation was made against the available experimental results for the parent hullform. The validation showed a goodagreement. The validated numerical modelling was used in the new hullform evaluation. The results showed that despite the larger displacement, the new hullform hydrodynamic performance is similar to the parent hullform.
