Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


Can assess and explain the meaning of the general model of a rigid body motion in 6 degrees-of-freedom and its applicability in ship dynamics. Can describe common approximations to the general model known as linear seakeeping and assess their applicability and deficiencies. Can describe the general theory of surface waves and modelling of regular and irregular waves. Can assess, using the learned mathematical models, the dangers associated with ship operation in irregular surface waves. Can understand the concept of loading of rigid and flexible ship idealizations in waves and apply principles of hydrodynamic modelling for rational ship design. Can understand the basic principles of hydrodynamic model testing and full-scale measurements.
