Risk-based decision-making support model for offshore dynamic positioning operations

چکیده
A Dynamic Positioning (DP) system enables vessels and rigs to accurately maintain a predetermined position heading or track. It precise operations under harsh environmental conditions. DP is used for variety of purposes; however, the role operator (DPO) considered same regardless type operation: monitor keep vessel in position. Some decisions that DPO makes are safety critical, example, about set-up can prevent from colliding with an offshore oil gas platform. Applied cognitive task analysis (ACTA) performed analyze how different operational settings influence decision-making DPO. Two DPOs experience five operation types were interviewed. The results ACTA compared respect technical steps, cues, steps components, actions, decisions. contextual factors evaluated using adapted version Rasmussen’s dynamic model. comparison evaluate current DPO, light operations. Recommendations improvement safety, design system, training formulated.
