3 Simulation Method
Below we consider only the sea wave loads in evolutionary operator in (1). This operator acts on
every node V of CN: the coordinates of the nodes are changing every time step. Thus, the links break
when the distance between nodes are greater than the sight limit. When the was out of sight again
(which it is possible due to periodicity of wave motion), the links restore. It should be noted that we
have considered only the wave load. Wind and tidal currents are not taken into account .
