Abstract

The article presents a method of estimating navigational safety in restricted areas using the method of navigational risk; a method of optimizing the designing of pilot navigational systems and prototypes of optimal pilot navigational systems (stationary and portable) constructed at the Maritime University. 1 Introduction The admissible size of manoeuvring vessels is decreased and their movement parameters are altered in restricted areas at night and in times of impaired visibility. In the case of vessels operated on regular routes, hydrometeorological conditions cause them to be delayed, and attempts at eliminating those delays lead to heightened navigational risk. The restrictions on admissible size of manoeuvring vessels in these areas and their delays are caused by: − inaccurate knowledge of the vessel manoeuvring in the area at each moment of performing the manoeuvre, − inaccurate knowledge of the vessel’s manoeuvring characteristics in particular navigational conditions. These restrictions can be eliminated by applying specially designed pilot navigational systems. The concept of a pilot navigational system consists in providing the master or the pilot conducting the vessel with information facilitating the safe performance of the planned manoeuvre in particular navigational conditions in set time. The information provided must be:
