A method for providing guaranteed trouble-free movement of a surface or underwater vessel in various emergency situations in presence of underwater and surface potentially dangerous objects (PDO), including emergency situations, when using conventional ship maneuvering it is impossible to avoid a collision with a PDO, includes constant data reception of satellite navigation systems, data from radars, automatic identification system, positioning of the vessel, calculation of the vessel speed, depth under a keel. In order to increase probability of collision avoidance of a surface or underwater vessel in waters with underwater or surface potentially dangerous objects the following additional actions are carried out: receiving a three-dimensional image of the underwater situation, not only under the keel of vessel, but on all sides: in front, aside and from the rear using sonar in front, back, left and right areas; in case of PDO identification they are recognized or by skipper himself, or a recognizing device and an optimal method is selected to avoid a collision of the vessel with the PDO followed by calculation of the trajectory of deviation from the PDO. |
