Based on the NURBS representation of the ship hull surface and deck, polyhedron representation of the inner bottom & shell, the efficient plane-surface intersection algorithm and the geometric properties calculation method, the virtual subdivision and hold capacity calculation method for arbitrary shapes of compartments are presented.

At same time, there are more and more shipwrecks and people have realized the importance of protecting environment experts begin to put their strength on VLCC s subdivision and stability.
