AN INTEGRATED APPROACH TO ENSURING NAVIGATIONAL SAFETY OF LARGE-SIZED CONTAINER SHIPS IN CIRCULATION IN SHALLOW WATER AREAS

Abstract

The main task during navigation of big-size vessels is to ensure navigational safety in shallow water areas of waterside during turning. In the article objective reasons that influence on the safety of navigation of big-size carriers during turning in shallow water areas of water side which lead to increase of maritime accidents involving stranding and touching the ground, raids on hydraulic structures and vessels.

The analysis conducted revealed insufficient integrated approach to joint accounting of structural, maritime, hydrometeorological and hydrological factors and their impact on the management of big-size vessels and their movement along the planned safe trajectory. The question of hydrodynamic interaction of the vessel and the soil, operational stability of the vessel on the course, change of the parameters of turning in shallow water have been studied.

Mathematical dependences with the help of which it is possible to calculate some safe parameters of navigation in shallow water in the form of depths, speeds, changes of turning radius are analysed. Practically unexplored factors which influence the safety of navigation of big-size container carriers in turning in shallow areas of the water arrears have been identified.

A conclusion was made that the use of existing methods to ensure the safety of navigation in shallow waters is important, but does not cover the full range of safety measures that must be applied to keep the vessel on the planned trajectory. The list of different factors affecting the safety of navigation of big-size vessels, given in the analysis of recent studies and publications in this article, requires further research for their comprehensive accounting during navigation in shallow areas of water areas.
