The paper presents possibilities for improving the positioning accuracy of ships equipped with dynamic positioning systems by using other methods or systems. In extremely unfavorable situations, where it may be impossible to maintain the operation of the industrial part of multifunctional ships, there is a need to support positioning systems with additional systems that will maintain acceptable operating conditions. Furthermore, after exceeding critical parameters, they will help ensure the safety and survival of the ship and its crew. There are several possible solutions, which are indicated in the paper. An attempt has been made to analyze this problem.
The propulsion system of a multifunctional ship should meet the obtained dynamic positioning class during operation under specified external conditions, designed for a given type of ship, along with the reliability of supplying the industrial part with electrical energy of appropriate quality [5]. The development of ship thrusters has enabled the construction of ships that can independently meet the requirements for accuracy in maintaining speed and the required heading (movement of the hull relative to the cardinal directions) or maintaining a position relative to a specific point on the seabed [3,6,7].
