EN-4151
Applied Naval Architecture for Marine Engineers
Course Description
The course includes general naval architecture nomenclature, ship sizes and geometry, hydrostatic curves, transverse and longitudinal stability calculations, identification of principal structural members, and calculations for ship strength curves. The course also studies resistance relationships between an actual ship and a ship model, ship propulsion design requirements, and sizing of a ship’s engine and power plant.
