DESCRIZIONE
A device for operator guidance of a ship, comprising: means for providing an indication of the sea wave motion; means for determining rigid body ship motions, said means being operatively connected to said means for providing an indication of the sea wave motion; first means for determining and providing structural stresses of the ship operatively connected to said means for determining the ship motions; means for determining and providing an indication of wave impacts on the ship operatively connected to said means for determining the ship motions; second means for determining and providing structural whipping stresses of the ship operatively connected to said means for determining and providing an indication of wave impacts on the ship; means for determining and providing the combination of the stresses operatively connected to said: - first means for determining and providing structural stresses of the ship operatively connected to said means for determining the ship motions and to said - second means for determining and providing structural stresses (whipping) of the ship operatively connected to said means for determining and providing an indication of wave impacts on the ship; means for the graphical and/or numerical display operatively connected to said means for determining and providing the combination of the stresses.
