Dynamic positioning (DP) drive off (DO) reduction with inertial navigation system

摘要

A system and method are disclosed for controlling a ship to determine if a ship is experiencing a drive off event, identify a subsystem that causes a drive off event, and correct the drive off event. The step of determining is performed using a processor of a dynamic positioning control system to determine whether there is any discrepancy between the modeled vessel motion and the measured ship motion, And processing the measured ship motion. The dynamic positioning (DP) control system may then take action to control the ship's movement, at least in part, based on the modeled ship movement and the processing of the measured ship motion.
