Ship motion calculation
WebThe mathematical model, which describes the ship maneuvering motion, is developed employing the coupled equations of surge, sway, yaw, roll and propeller revolution. … WebGenerally, ships can experience three types of displacement motions (heave, sway or drift, and surge) and three angular motions (yaw, pitch, and roll) as shown in Figure 1. The general equations of motion have been developed either by using Lagrange's equation (see, e.g., [1–4]) or by using Newton's second law (see, e.g., [5–7]).
