The concept of dynamic ship positioning systems dates back to 1960, when there was a need to ensure a ship’s position relative to the seabed for drilling units in the fuel industry in deep-water areas, where positioning using deployed anchors proved unfeasible. The technical capabilities of that time were limited, especially in determining the exact position of the ship. As a result, in coastal waters, the ship’s position was determined using land-based reference points and radio beacons, and then the ship’s position was corrected using propulsion. The accuracy of the ship’s positioning was poor and exceeded 100m from the designated location.It was only with global satellite positioning systems (American GPS, Russian (…)
