This paper presents an approximate method for taking into account finite stiffness of bottom grillages in strength calculations of ship installed on one keel track in the dry dock. It compares the approximate method and FEM results for the docking of a 600 t barge platform. The results have shown good correlation. It has been demonstrated that local stresses in the keel near transverse bulkheads might become quite significant.
