Validation Studies of the Numerical Tool PANSHIP for Predicting the Calm Water Resistance of the Armidale Class Patrol Boat
Abstract
DSTO has recently joined the International collaborative consortium FAST3.JIP with the aim to develop a numerical capability for the prediction and analysis of the resistance, seakeeping and seaway loads of high speed semi-planing hullforms. It has been reported previously that DSTO has undertaken a series of calm water resistance scaled model tests on the Armidale Class Patrol Boat (ACPB). In addition to this, DSTO has also undertaken a series of full-scale calm water resistance trials onboard an ACPB. Both the experimental data and full-scale powering trial data has been used to validate the numerical tool PANSHIP. It was important to ensure that the calm water behaviour across the range of speeds is predicted correctly as this ensures the correct pressure distribution under the hull is predicted and hence the ship motions are accurate. Once fully validated this tool can be utilised to increase the understanding of any potential fuel saving strategies for the ACPBs and the through-life structural management of the platform. This report presents the outcomes from this validation study showing the results of the PANSHIP predictions for experimentally obtained running trim, rise of centre of gravity and total resistance versus speed relationships and for running trim and total resistance versus speed relationships obtained from full-scale trials.
