Abstract

Abstract: To improve the computational accuracy of ship floating condition, a method of ship floating calculation was proposed based on CGAL (Computational Geometry Algorithms Library). By using the slicing module in CGAL, the offset table was obtained through longitudinally slicing 3D design surface; The shell data were gained by simplification and equidistant offsetting; The Jacobi matrix coefficients were achieved by intersecting water plane and shell data; Ship floating condition equations were solved by Newton iteration method. Taking Bulk carrier "SHANDONG REN HE" as an example, ship floating calculations under ten typical loading conditions were carried out. The computational error between calculated results and those given by the loading manual was relatively small. Compared with traditional methods, the method can be used to calculate arbitrary floating conditions in real-time with high precision and has a certain engineering application value.
