ABSTRACT
Hydrostatic curve is one important technical data for vessel design, vessel building, marine transportation and other related business. With hydrostatic curve, parameters about performance of vessel navigation can be computed, which can improve navigation safety and complete scientific cargo distribution. Compared to traditional conversion from 3D vessel hull to 2D plane computation methods, this study, by applying affine transformation theory, presents water-line plane equation determined by floating parameter, calculates precisely vessel hydrostatic properties under arbitrary floating condition by using the intersection algorithm of the plane and the surface as well as the universal algorithm for arbitrary sealed polygon and arbitrary sealed polyhedron. Hydrostatic performance computation results of sample real vessels including cargo arrangement and stability curve under given loading condition confirm the validity of these proposed algorithms.
