Sinkage of anchored vessels in waves

The sinkage of selected five different displacement of container ships, tankers and bulk carriers in different waves and depth are respectively calculated by using SESAM software based on three-dimensional potential flow theory of ship hydrodynamics, and the curves of which the draft rate of the ship's vertical motion changed with displacement are obtained. And then the mathematical relationship between the sinkage of anchored vessels in waves and the ship's draft is summarized.
