Account of navigational hazards when the ship and the target are avoiding collision at small distances

Keywords: navigation safety, navigation in confined waters, consideration of navigational hazards, prevention of ship collisions at sea, safe evasive maneuver


Successful, fast and high-quality solution of the important problem of ensuring the safety of navigation and navigation leads to a significant improvement in the protection of human life at sea, as well as to a constant reduction in harm to the environment, property and other equally priority production processes in maritime transport.

The navigation of modern large-capacity and high-speed ships of large sizes in cramped and limited areas is complicated by intensive navigation, with a much greater presence of navigation hazards and navigational obstacles that create the prerequisites for the occurrence of complex, non-standard and, sometimes, even emergency situations. Therefore, more than 80 % of all navigational accidents occur every year in cramped and difficult for safe navigation waters, which confirms the great complexity and danger of navigation conditions in cramped and limited waters.

This article is devoted to taking into account various navigational hazards when choosing a safe maneuver for divergence between the ship and the target at small distances between them.

The case of taking into account a point navigational hazard in the case of an excessive approach of a ship to a dangerous target is considered. For a situation of emergency divergence of a ship with a dangerous target, a choice of a safe evasive course is proposed, taking into account the linearly distributed navigational hazard.

The aim of the article is the procedure for analytical accounting of navigational hazards when the ship and the target diverge at short distances
