Opis:
This article presents basic principles of using simulation research in marine traffic engineering and describes a simulation method of waterway design. The author indicates the most common errors made when the procedures of simulation research are not followed, despite advanced ship handling simulators used, which makes it impossible to satisfy the criterion of conformity between the examined system and its model. Practical use of results thus obtained leads to the breach of safety criteria or overdimensioning of waterway system. The presented simulation method of waterway design has been developed by this author. Applying the procedures of the method ensures that the mentioned conformity criterion is fulfilled.

Opis:
This paper concerns an algorithmic method for preliminary selection of parameters of ship propulsion system fitted with fixed screw propeller in the case when the ship’s operation is associated with significant changes of waterway depth and width, hull resistance of the ship and its service speed. Mathematical model arguments of the considered design problem are main ship design parameters identified in the preliminary design stage. Structure of the formulated model complies with formal requirements for continuous- discrete mathematical optimization problems. The presented examples of application of the method concern an inland waterways ship fitted with compromise screw propeller optimized in the sense of minimization of fuel consumption for passing a given route distance within a given time. The elaborated method may be especially useful in designing such ships as : coasters, inland waterways ships, tugs, pushers, trawlers, mine sweepers, icebreakers etc.

Opis:
This paper presents a proposal of a parametric method for predicting the characteristics of wake fraction, w(x) and thrust deduction, t( ) x , of ship hull of the draught close to waterway depth. The method makes it possible to take into account an influence of low waterway depth in preliminary selecting propulsion system parameters of ships intended for operating in shallow waters, e.g. of inland waterways ships. The mathematical model of the problem was determined with taking into account the aspect of coding easiness of calculation algorithm to be applied to computer software useful in computer aided design. Application of the method was demonstrated with the use of the example characteristics of the passenger ship intended for operating in shallow waters on Berlin-Kaliningrad route, whose design was elaborated in the frame of the EU Eureka INCOWATRANS E!3065 project.

Opis:
This paper presents a method for estimation of mass characteristics of vessels, elaborated with the use of an algorithm based on requirements of the Rules for the Classification and Construction of Inland Waterways Vessels of Polish Register of Shipping, and on a simplified method [6] for determination of mass of hull plating stiff"eners. The dimensioning method of hull structure scantlings based on this algorithm concerns classical vessels intended for the carrying of general cargo, dry and liquid bulk cargoes, which determine the range of the method application. The method does not cover vessels of different construction, e.g. roll-on-roll-off type vessels equipped with heavy decks, as the dimensioning of their scantlings is based on different relationships and models.

Opis:
This paper presents a method of predicting effective power demand (brake horse power – B.H.P.) for propulsion of inland waterways push train, useful in the preliminary design stages. By using it, on the basis of known main particulars of a given push train, i.e. its length, breadth, draught and speed, a generalized Admiralty formula can be determined and then the pusher propulsion power can be preliminarily predicted by making use of the elaborated structure of the formula. Application of the method is illustrated on the example of a two-segment push train of inland waterways passenger ship designed in the frame of the Eureka INCOWATRANS E!3065 project.

Opis:
The increasing sizes of ships and lack of functionality of the existing solutions determine the interest in rebuilding the already existing solutions. Simulation models allow to analyse the possible modernisation variants taking into account the variability of elementary parameters. The article presents analysis results for the Przemyslowy Canal in Szczecin with respect to navigation safety and regulating traffic regulations in the Przemyslowy Canal taking into consideration the interests of all subjects involved. The paper applies real-time simulation methods based on manoeuvring simulators. After a thorough analysis that took into account the safety of navigation, further possibilities of development have been determined. Study results are aimed at designing new solutions in case of modernization of the Przemyslowy Canal in Szczecin.

Opis:
This article aims to analyse the statistical parameters of waterways forming the entrance to the port and the construction of a model for determining the optimum parameters of the entrance to the port. It has been analyzed parameters of the entrances to the 100 selected global ports, based on the analysis it was examined the interdependence between certain parameters and the impact they have on the maximum size of the ship which can enter to the port. This analysis allowed to develop a model, which can possible to be applied to the entrance of initial port design.
