WebSep 16, 2024 · Dynamic positioning (DP) for station-keeping control keeps the position and heading of the vessel constant regardless of environmental disturbances from wind, waves and currents. If the point of interest on the vessel has a significant vertical offset, it will be influenced also by the roll, pitch and heave motions. Although such motions are usually … WebApr 13, 2024 · It is used to describe the blade pitch motion. The six DOFs motions of the floating platform are composed of three translational components (surge, sway, and heave along the O-XYZ axis) and three rotational components (roll, pitch, and yaw around the O-XYZ axis). The key inertial parameters of the FOWT system are presented in Table II.
