Learning Outcomes


Acceptance criteria for vibrations on ships; methods for the calculation of natural frequencies and forced vibrations of sructural components and the entire hull girder; effect of exciting forces of the propeller and main engine and methods for their determination.


Acquaintance with methods for the calculation of natural frequencies and exciting forces and resulting vibrations of ship structures including their assessment; modelling of structures for the vibration analysis.


Ability to detect vibration-prone components on ships, to model the structure, to select suitable calculation methods and to assess the results.
