A 130m long ship has a radius of gyration of kyy 31.392m, a longitudinal metacentric height GM of 130m and a displacement force of 125000kN. If the damping moment for pitching motion b is 9417600 kN. if the damping moment gor pitching motion b is 9417600 kNms and and the amplitude of pitching moment Mo is 1300000 while the ship is pitching in head seas (x=180 degree), determine the amplitude of pitching motion (theta)?The added mass moment ofinertia is 50% of the mass moment of inertia of the ship.
