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.

  • valid for whole curriculum period:

    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.

Assessment Methods and Criteria
  • valid for whole curriculum period:

    Marking scheme 1 - 5 ; Mark awarded by examinations (30% 1st mid term exam, 30% 2nd mid term exam OR 60% from final exam) and compulsory assignments (20% from group assignments 1 - 5 ; 20% from submission of final group assignment).

  • valid for whole curriculum period:

    The course comprises of 10 lectures, 5 assignments submitted bi-weekly, a final reportand exams.Under the assignments the students work in groups to develop ideas on how ship dynamic considerations influence the ship design they developed under MEC-E2001 (Principles of Naval Architecture). These group work efforts usually run in parallel to the ship design portfolio course (MEC-E2011) and ship structures (MEC-E2007). Therefore the final report is a summary of their overall study in these courses.
