Operational voltage levels can force a.c. power systems into non-linear behaviour. The system global characteristics are presented in bifurcation diagrams, generated using an electromagnetic–transients program. They reveal the onset of ferroresonance, period-doubling and chaos when series capacitance is present between the supply and saturating transformers.
The numerical prediction of green water loads on super-structures is challenging due to the high number of required calculations to identify the critical operational conditions in the seaway which lead to overcoming seawater on deck. Further, the simulation of the non-linear behaviour of water on the deck and the prediction of impact loads require high computational effort. This paper presents an efficient three-step approach to simulate green water loads. The application of the developed procedure will be demonstrated on a mega yacht geometry.
