Abstract

New approaches to the information support of navigators are considered in the paper. They can positively influence the increase in the level of providing the modern navigators with the navigation information necessary for making decisions that make it possible to safely perform maneuvers when passing navigational hydraulic structures on inland waterways using 3D electronic navigational charts. As such approaches, a number of constructive proposals for the following methods modernization have been proposed: controlling the vessel in course, controlling the vessel in speed, controlling the velocity vector of the vessel, as well as controlling the bow and stern ends of the vessel. When navigating a vessel in course, a sequence of actions when the vessel is turning is disclosed. When considering the control of a vessel in speed, an example of displaying information on a change in the navigation situation with a change in the water level, which is important in ensuring the safety of navigation, is considered. When considering the control of the ship’s velocity vector using the 3D image of the Bagaevsky waterworks as an example, the possibility of performing a visual assessment of the spatial dimensions of objects and ships when implementing the method is emphasized. In addition, the fragments of 3D electronic navigational cartography those display the maneuvers of vessels entering a double-lane lock, showing the implementation of controlling the bow and stern ends of the vessel are presented. In the proposed study, based on the application of elements of situational analysis and methods for assessing the navigation situation by the skipper, when performing maneuvers, the recommendations that will improve the navigation safety through the use of standard electronic navigational charts and the latest 3D navigational charts are suggested.
