On the influences of loading cases and inertial characteristics on the behaviour of a floating crane

The evaluation of the dynamics of floating structures has to be investigated in order to define the operational index which is reflecting the ability to operate at certain sea state. The applications have been performed for a floating crane using a range of operational loading cases and sea states in the Black Sea coastal area. The influence of the way to evaluate the moments of inertia for the different loading cases is also systematically taken into account. The conclusions are formulated based on the comparative diagrams, incorporating the influences of the above mentioned parameters.
