The calculation model of strike risk at mooring
The paper considers the possibility of the strike of vessels moored to each other in the open sea from the point of view of their safety. The dependences defining mathematical expectation of a part of the moored vessel trajectory leading to a dangerous approach of vessels and possible strike have been obtained. The model of an interval estimation has been designed for increasing the veracity of the strike prediction.

On account of wind in the mathematical model of ship in order to estimate its influence on manouvring characteristics
The mathematical model of ship needs some parameters influencing on external factors, namely wind, in order to model the ship's movement while carrying out complex manouvring under real sailing conditions. The method of mathematical description of the wind influence on the ship manouvring characteristics has been given in the paper.

On account of shallow waters in the mathematical model of ship in order to estimate its influence on manouvring characteristics
The mathematical model of ship needs some parameters influencing on external factors, namely shallow waters, in order to model the ship's movement while carrying out complex manouvring under real sailing conditions. The method of mathematical description of the shallow waters influence on the ship manouvring characteristics has been given in the paper.

Loading diagram for modelling of operation of propulsion-steering complex of the "Astrakhan" type
The existing loading diagrams of determining the hydrodynamic characteristics of the vessel propulsion-steering complex are rather various. The authors have tried to find the most acceptable loading diagram accounting the design philosophy of the vessel.

On calculation of minimum allowable tanker speed at mooring at windy weather
The navigator should possess sufficient knowledge concerning vessel behaviour in different navigation conditions. To determine the minimum allowable speed of the vessel movement under conditions of wind influence is of great importance for safe mooring. The paper considers the solution of this task as applied to the conditions of point mooring of a tanker to a buoy which is an element of the tanker connecting device to the oil-pipe line.

Modelling of a tanker arrival at a conventional point according to the given trajectory
The paper considers the modelling of tanker arrival at a conventional point according to a given trajectory. The authors have proved that the most acceptable trajectory of tanker approaching to the conventional point is a pursuit path. The paper contains the results of this process modelling in the presence of the external disturbing factors (wind, heavy sea, current) in the manoeuvring region.
