A SYSTEM FOR THE ANALYSIS OF THE DYNAMICS OF VESSELS AND PLATFORMS MOORED OFFSHORE

A systematic approach for the numerical simulation of the behaviour of vessels or platforms moored offshore is presented. The paper illustrates how different analytical techniques are used in various applications. Among the applications discussed are those of vessels moored to conventional pier-type offshore loading terminals, vessels or platforms moored to offshore multi-point moorings and finally single-point moorings. The theoretical background for each of the analyses is presented. The hydrodynamic coefficients and wave excitation are evaluated by both strip theory and 3-D source distribution and the suitability of each approach is discussed. Cases of applicability of the frequency-domain solution versus the time-domain analyses are discussed for regular and irregular sea conditions. Finally, results from Computer Software Package VESDYN which incorporates the analytical techniques presented in the paper are compared with experimental results.
