AN ADVANCED METHODOLOGY FOR PRELIMINARY HULL FORM DEVELOPMENT

ABSTRACT A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping‐optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping‐optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point‐design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer‐supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.
