The paper deals with use the satellite navigation system for increase safety of navigation in difficult areas. There have been presented an algorithm to ship control procedure during environmental disturbances in narrow passages.

The paper describes some specific manner of M/F “Polonia” manoeuvring at the Ystad harbour where she is regarded to be “over maximal ship” and also M/F “Gryf” manoeuvring at Trelleborg, taking part into consideration the effect of wind pressure into the ship’s superstructures and houses.

Content available remote On the Control of CPP Ships by Steering During In-Harbour Ship-Handling
EN
This paper describes the results of experimental and simulation studies that aimed at developing effective control methods for single-CPP single-rudder ships during the coasting manoeuvre and the stopping manoeuvre. In order to improve the manoeuvrability of CPP ships under coasting, the authors performed full-scale experiments and confirmed that CPP ships under coasting using the Minimum Ahead Pitch (MHP) of CPP are controllable by steering. A simulation study was also conducted to evaluate the ship-handling method during the stopping manoeuvre that applies a turning moment to the ship by the maximum rudder angle steering prior to the reversing operation of the CPP and it is confirmed that CPP ships can be controlled sufficiently by the proposed method.

The paper presents the problem of the influence of current on ship during the manoeuvre of the turning and influence on this manoeuvre. The test of the different qualification of the influence of current on the manoeuvre of the turning of the ship was undertaken. The analysis of the influence of the current was conducted on this manoeuvre.

Sea–river ships can connect the area inside of land with oversea places without of indirect trans- shipment. In many cases the sea-river ships move on waterways (natural and artificial) inside of land for hundreds kilometres. Navigation in inland waters has to meet the same requirements as those for pilot navigation. This is due to the relations between the ship size and other objects on water area. These ones caused the navigation more hard then on open seas. The paper presents the criterion of safety assessment of navigation during sea-river ships manoeuvring ship in inland waters.

Briefly characteristic of m/f „Polonia" ferry has been presented. For the port of Ystad, topographical, hydro and meteorological conditions have been described. Moorings of the “Polonia” ferry at the port of Ystad have been discussed. Researches based on experts’ questionnaire and statistical methods of analyses have been exemplified. Finally there are some conclusions concerning improvements of ferries manoeuvres safety.

Using modeling and simulations has established itself as the most effective approach of preparing personnel engaged with crisis management, including the training of port security responsible personnel. On the background of presenting the overall methodology of transforming Bulgarian Harbour Protection System, the paper formulates a set of requirements for port security related education and training and proposes a general model of a simulating complex supporting the education and training process.

Content available remote Analysis of Ships Turn Manoeuvres in Port Water Area
EN
The turning basin is a special part of port water area described by dimensions in horizontal and vertical directions. Such area should be insuring the proper level of safety due to ship manoeuvres. The paper presents the analysis of ships turn manoeuvres on aspect of turning basin designing. The examples of such basins in polish port are showed.
