DYNAMIC POSITIONING (DP) DRIVE-OFF (DO) MITIGATION WITH INERTIAL NAVIGATION SYSTEM

摘要

Systems and methods for determining if a vessel is experiencing a drive-off event, identifying a subsystem causing the drive-off event, and controlling a vessel to correct the drive-off event are disclosed. The determining may include processing, with a processor of the dynamic positioning control system, a modeled vessel motion and a measured vessel motion to determine whether there is a discrepancy between the modeled vessel motion and the measured vessel motion. The dynamic positioning (DP) control system may then take action to control vessel motion based, at least in part, on the processing of the modeled vessel motion and the measured vessel motion.
