The paper presents the consequences for DP systems during emergency or unexpected situations like failure one or more gensets, failure one of propulsion unit, overloading electric system, getting off the course, vessel abandonment of DP work, etc. The design of DP system takes into consideration required the DP system class, the requirements of adequate classification society under supervision the ship is built. It is necessary to fulfil the system redundancy in normal operation states. When failures occur in the vessel systems, it changes the possibility of DP work. There are three DP alert levels: green, yellow and red needed the proper responses. It was prepared required procedures for crew according to ISM Code, IMCA and IMO regulations. For the vessel safety, it is important the training process all crew members, especially one of the navigating officer as DP operator and one of the engineer or electrician. They ought to know their duties during alarms, exercises and real situations, especially in DP operation. The human factor ought to be taken into account as well. The DP operator may directly initiate the loss of vessel position or interact with technical failure events, which then contribute to a loss of vessel position. The important problem to solve is how to avoid emergency situations. It’s time for quick and important decisions for further vessel’s activity.
