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.
LEARNING OUTCOMES
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.

CONTENT, ASSESSMENT AND WORKLOAD
Content
Valid 01.08.2020-31.07.2022:
Ship theory in terms of seakeeping and loading. Linear surface wave theory. Ship motions in 6 degrees of freedom. Strip theory, 3D panel methods for the evaluation of rigid body motions and hull girder loads. Introduction to hydroelasticity of ships. Equipment for motion control. The non-linear effects of surface waves, ship dynamics and motions and loads. In the assignments, students assess the seakeeping and hull girder loads of their concept ship by applying state of the art hydrodynamic modelling principles. Introduction to experimental and full-scale measurement methods.
