A recently granted patent (Publication Number: US11965300B2) discloses a system for controlling a motion-compensated pile guide for a floating vessel during the process of driving a monopile into the seabed. The system includes a pile guide, an actuator for horizontal movement, a control unit, and sensors for determining the inclination angle of the monopile and the force exerted on the pile guide. The control unit is designed to maintain the horizontal position of the pile guide by compensating for the vessel's motion, minimizing the inclination angle by adjusting the force applied, and moving the pile guide accordingly.

Furthermore, the patent details additional features such as setting a predetermined force level, using hydraulic cylinders as actuators, employing pressure sensors for measurement, determining the desired force based on soil structure, and incorporating an algorithm for vessel motion compensation. The system aims to optimize the driving process by ensuring the monopile remains in a vertical orientation, thus enhancing the efficiency and effectiveness of pile installation operations in offshore environments. The patent also covers a method for implementing the system, emphasizing the importance of controlling the force applied to the monopile based on its inclination angle and the soil conditions, ultimately improving the stability and accuracy of the installation process.
