Students will get acquainted with different types of maritime structures, their function,
installation procedures and sub-systems. They will learn to understand the physical
and mathematical modelling of maritime systems exposed to a marine environment
including waves, wind and ocean currents. These models are the basis for the
analysis of hydrodynamic and aerodynamic loads on ships and marine structures as
well as their wave, wind and current induced motions. Furthermore, students gain indepth
knowledge of linear and nonlinear mathematical models as well as selected
experimental methods. They will be able to predict loads and movements of maritime
structures, floating and fixed, selecting and applying the most suitable methods
according to the specific technical task. Finally, they will be able to evaluate and
synthesize the results of theoretical and experimental analyses in a professional and
qualified manner.
