Modelation of the oscillatory motions of the ship for the Mediterranean Sea navigation conditions, using the Octopus software

The paper presents a complex study about oscillatory motions of a ship for offshore industry in the Mediterranean Sea conditions of navigation. Geometrical, constructive and hydrodynamic particularities of these special vessels make it interesting and also necessary – for the safety of the navigation and operation of the ship – this study for the ships movements, considered as a rigid body with six degree of freedom. The study provides information regarding RAO (Response Amplitude Operator) operator of the ship for the displacement of gravity centre of the ship, related with the incident wave systems in the Mediterranean Sea, interpreted by the Jonswap energy spectrum, and other several conclusions. For the study, are used features offered by OCTOPUS as a tool for modelling and simulation – software that allows the study of the computerized behaviour of the ship on the waves in the real sailing conditions. Program library was used for both the vessel itself and navigation modelling environment (for regular waves as well for the irregular waves which was modelled using Jonswap energy spectrum).
