Abstract

The Dynamic Positioning (DP) system is a vital technology on modern offshore vessels for automatically maintaining vessel position and heading without the assistance of anchors. The operational success of a DP Class 2 system depends heavily on the reliability of integrated components, including the control and steering systems. This study analyzes the failure risks of the control system and rudder blade during the Dynamic Positioning Trial on MV Walker Tide using an integrated Failure Mode and Effects Analysis (FMEA) and SWOT analysis. Actual testing revealed an anomalous phenomenon in test number 28 (Failure of Feedback Signal Test), in which disconnecting the feedback signal caused the propeller pitch angle to move uncontrollably toward a 45% reverse-pitch position and triggered a loss of position. Based on the FMEA analysis, the Rudder Actuator component has the highest risk priority with a Risk Priority Number (RPN) of 250, followed by the Communication Network and Redundancy System with an RPN of 200, and the Feedback Rudder Sensor with an RPN of 192. The IFAS and EFAS matrix analysis places the organization in Quadrant I (Growth Strategy), recommending an aggressive Strength–Opportunity (SO) strategy through optimization of digital predictive maintenance, strengthening of emergency redundancy systems, and improvement of certified crew competencies.
