It is often necessary in dynamical analyses to take into account their flexibility. A convenient and efficient method for modelling them is the rigid finite element method in a modified form. The rigid finite element method allows us to take into account the flexibility of the beam system in selected directions while introducing a relatively small number of additional degrees of freedom to the system. This paper presents a method for modelling the pedestal, the frame and the boom of an offshore column crane, treating each of these components in a slightly different way. A custom approach is applied to the pedestal, using rigid finite elements of variable length. Results of sample numeric computations are included.}, type={Artykuły / Articles}, title={Application of the rigid finite element method for modelling an offshore pedestal crane}, URL={http://rhis.czasopisma.pan.pl/Content/84780/PDF/10_paper.pdf}, doi={10.2478/meceng-2013-0028}, keywords={offshore pedestal crane, dynamics, modelling, rigid finite element method}, }
