	abstract = {The Dynamic Positioning System is classified into three types: DP class A, B, and C. DP class A vessels hold an overwhelming market share, but it lacks redundancy and is prone to failures. Therefore, in case of failure, there is a possibility of loss in positioning. Herein, we postulated that training Dynamic Positioning Operators (DPOs) for emergencies should mitigate maritime incidents. Accordingly, simulators have been proposed for achieving this objective. Using an experiential approach, nine DPOs were exposed to DPS simulation emergency response training at a lab in Japan. Each participant was given four tasks and a checklist to assist in decision-making to avoid collisions in various scenarios involving marine structures. An analysis of the simulator experiments and outcomes indicated that the length of experience in ship handling and prior training influenced DPOs performance. The study concluded that DPOs should take more effective training to maintain proper positioning for the safe operation of DP vessels.},
