THE ROLE OF MODEL TESTS AND THEIR CORRELATION WITH FULL SCALE OBSERVATIONS

The behaviour of offshore floating structures is partly static and partly dynamic. To benefit fully from the results of experiments or calculations, model tests and an analysis by computational methods should be conducted in accordance with a theoretical model of the occurrences. To construct a theoretical model of this type it is advisable to deal with the two parts separately. This procedure is justified by considering the environmental conditions more closely. The statics of the performance can easily be determined by calculations or by model experiments. The cyclic oscillations of a quantity produced by waves should be studied by spectral techniques and statistical methods. The ultimate result is a stochastic variation around a certain non-zero level. Due to the random character of sea waves a deterministic description cannot be given. To illustrate the above procedure a correlation is made between calculations and full scale measurements of the values of parameters such as horizontal and vertical motions and anchorline forces on some floating structures.
