Propulsion angle and propulsion control device and method of floating offshore plant

摘要

A pair of thrusters are placed at the same distance from the central axis of the turret in the stern section of a floating offshore plant moored at one point using a turret, and the direction of travel even when a straight thrust is generated with the same force. It relates to an apparatus and method for controlling the bow angle and propulsion of a floating offshore plant to prevent this inclination and to apply the same mathematical model for control, which can be operated and moored at sea, and can be swiveled on the bottom of the stern side. Control the bow angle and propulsion using a plurality of propulsion devices attached to the stern, but the plurality of propulsion devices are a pair of thrusters disposed at the same distance from the central axis of the turret for mooring on the inner bottom of the stern. Including, the bow angle and propulsion control device of the floating offshore plant are implemented.
