Summary

Several analyses have been carried out validating the ability of AquaSim to calculate response of large mass moored vessels. The hydrodynamic loads to the vessel is calculated integrated with motion and forces in the mooring system such that nonlinear response is accounted for. This document shows how forces from hydrodynamic loads are introduced to AquaSim. The document describes the options AquaSim users have to account for the load components which are of importance for response.

Relevant natural periods of systems and loads occurring should be carefully evaluated by the analyst to ensure that all relevant load-response-effects are considered.

The importance of velocity and mass of floating object, stiffness properties of moorings are shown both through analysis and analytical formulae. Analysis using AquaSim compares well with analytical formulae for cases where analytic formula can be established.

AquaSim shows good versatility.
