What Is The Parametric Rolling?
A vessel has six degrees of motion namely surge, sway, heave, roll, pitch and yaw. The port to starboard rotation about the centerline is called roll motion and the forward and aft motion about the midship is called pitch motion, both of which are associated with parametric rolling. Understanding Parametric Rolling Parametric rolling is a…
