**Assumptions:**

- A barge like vessel is floating on the still water surface, the motion, induced wave and added mass effect is neglected

- It's calculated a time series of linear roll and heave, with three degress of freedom (x, y and rad)

- Model is considered stable (GM > 0), and Roll ressonates when GM < 0

- Block Coefficient is used in calculations, but not plotted in the transversal and longitudinal animations

- The body fixed reference frame is located at the geometric center of the vessel
