A method for decreasing accidences in propulsion of surface or underwater vessel relates to shipbuilding and ship navigation, especially in potentially dangerous emergency situations. The method consist in three-dimensional imaging of potentially dangerous objects due to mounting azimuth search sonars at backward and forward semispheres and along left and right side as well. This enables to get accurate, detailed and current three-dimensional information in front, at the back, from the left and from the right of moving vessel. If potentially dangerous objects are detected near the vessel supplementary operations such as water jets are used to avoid collision with potentially dangerous object, and air cushions are actuated at the place of possible collision of shipboard with potentially dangerous object. The method provides increase of probability of accident-free propulsion of surface and underwater vessel in different dangerous emergency situations, including situation when vessel collision with potentially dangerous object is impossible to avoid. |
