Abstract:This paper presents an effective model-based thruster failure detection and isolation method for dynamically positioned (DP) offshore surface vessels. A DP vessel is supposed to maintain its position and heading at a reference point exclusively by means of thrusters. The occurrence of thruster failure may cause significant performance losses. Therefore, it is of great practical importance to timely detect and isolate thruster failures. In our proposed method, according to the prior knowledge of mathematical mo… Show more
