The subject matter are mainly in understanding of the fundamental principles of ship construction, theories and factors affecting trim and stability and necessary measures to preserve trim and stability. It includes the knowledge and understanding of ship welding, important uses of bulkheads, characteristics of watertight and weathertight doors, ship corrosion and its prevention, surveys and dry docking. The purpose of inclining experiment, effect of beam and freeboard calculations corresponding to pressure in liquids. Students will be able to calculate the effect of flooding on transverse stability, shearing forces, bending moments and torsional moments. torsional moments. They will be able to understand how to use (ADB) automatic database equipment and to determine the effect of flooding on trim calculations. More importantly are to determine the theories affecting trim and stability and the responsibilities under the International Convention Code.
