    The paper presents the results of experimental investigations of the flow generated by the controllable pitch propeller. The influence of the propeller pitch, rate of turn and rudder angle on the velocity filed measured behind the rudder for two different water depths were investigated. The model tests were carried out using twin propeller twin rudder car-passenger ferry model in 1:16 scale. The results of the experimental analysis allowed for the quantitative assessment of the velocity components distribution. The predicted flow field generated by the propellers near the quay wall during unberthing has been computed using CFD methods

    The paper discusses the influence of the main vessel operational parameters on fuel consumption. These parameters are the speed trough the water, mean draft and trim. The focus is set to the flow phenomena around certain elements of hull geometry as they are sensitive on the selection of discussed parameters. Therefore, the understanding of the flow properties and their impact on ship resistance thus the fuel consumption and emission is crucial taking into account legislative changes imposed by IMO with respect to carbon dioxide emissions from ships

    The paper presents the theoretical and experimental methods used in scientific and operational practice to predict the hydrodynamic loads generated by propellers and thrusters on the hydrotechnical constructions. The influence of different parameters: pitch and rotational speed of the propeller, aft body form of the ship hull and shallow water effect on the velocity field are discusse

    The paper presents environmental factors influencing the safety of ship access to a port. The factors are classified into real time, short and long term ones from the point of view of modeling and real time risk assessment. An example of a long term prognosis for a surface current is given. The risk assessment of ship approach to a port based on a stochastic model of ship motions under wind and wave is proposed.

    The paper presents the state of art on three dimensional transient flows induced by a ship approaching a berthing structure. The results of full scale measurements of the velocity field obtained during the trials conducted in Gdynia Port with the motor ship “Horyzont II” are given. At the present stage of research the results of measurements have been used for the qualitative assessment of phenomena and making preliminary conclusions regarding the hydrodynamic forces.
