Floating marinas, floating breakwaters and floating bridges are long structures made up of pontoons which are connected between them rigidly or with flexible connectors, and they are anchored at the bottom of the sea with mooring lines. They are usually placed in protected water regions. The waves in these regions are short crested waves. The dynamic analysis of long floating structures in short crested waves must take into account the special characteristics of the short crested wave loading, and the frequency depended load correlation along the structure. The structural modelling using finite element methods does not present any difficulties. However the part of the analysis which presents special problems is the modelling of the loading in a short-crested sea. General purpose finite element programs do not provide methods for calculating the loading in a stochastic, short crested sea,
