Direct prismatic coefficient variation to hull form surface

International Journal of Naval Architecture and Ocean Engineering
The initial ship design process aims to optimize the hull form to enhance ship efficiency. During this phase, hull form variations are executed based on a reference ship to meet shipowner requirements, such as altering the CP (prismatic coefficient) to ...

Hull form optimization with a new three-dimensional deformation strategy [PDF]

Scientific Reports
As a variant of the Lackenby method, the shifting method is widely used for global geometric deformation in hull form optimization. However, similar to the traditional approach, it is confined to longitudinal transformations, limiting adjustments in beam

Effects of Hull Form Variations on Resistance and Seakeeping Performance of Planing Hulls with and without Incoming Regular Waves [PDF]

Journal of the Society of Naval Architects of Korea, 2014
Planing hull forms have significant influences on those hydrodynamic performances in calm water and in waves. Therefore, the hydrodynamic performance of a planing vessel should be predicted by model tests or theoretical calculations, and be confirmed whether it shows the performance requirements at the design stage.
