Opis:: W opracowaniu przedstawiono rezultaty badań dynamicznego oddziaływania strumienia powietrza na model okrętu projektu 888. Badania przeprowadzono na stanowisku znajdującym się w Akademii Marynarki Wojennej. Wyniki wykonanych pomiarów porównano z obliczeniami teoretycznymi kąta przechyłu dynamicznego. Parametry wejściowe do badań i obliczeń określono zgodnie z zaleceniami przepisów Polskiego Rejestru Statków oraz IMO. Kluczowym zagadnieniem było określenie wartości momentu przechylającego od działania wiatru. Przeprowadzone badania wykazały, że przyjęty przez IMO i PRS sposób określania kryteriów stateczności dynamicznej okrętu zawiera margines bezpieczeństwa.
The paper deals with investigations into dynamic stability carried out for a model of type 888 ship. The investigations take into account geometric and dynamic similarity problem. Angle of heel caused by air flow is recorded and compared with calculations carried following recommendations by IMO. The results obtained indicate that the way to determine ship dynamic stability criteria adopted by IMO and PRS includes a margin of safety.

Opis:: Liquid sloshing phenomenon taking place in partly filled ships’ tanks directly affects the stability of a vessel. However, only static calculations are carried out onboard ships nowadays and static transfer of liquid weight is taken into account in the course of routine stability calculation. The paper is focused on a dynamic heeling moment due to liquid sloshing in tanks onboard ships. A number of numerical simulations of liquid sloshing taking place in a moving tank is carried out. The wide range of ship’s tanks is taken into account. The conducted CFD simulations are experimentally verified. Finally, the method of an assessment of the liquid sloshing impact on ship transverse stability is worked out. The key point of the method is a dynamic coefficient describing relation of the researched dynamic heeling moment and the quasi-static one in terms of dynamic stability of a vessel which is related to the weather criterion of ship stability assessment.

Opis:: Liquid sloshing phenomenon is a result of partly filled tank motions. As a tank moves, it supplies energy to induce and sustain a fluid motion. Both the liquid motion and its effects are called sloshing. The interaction between ship’s tank structure and water sloshing inside the tank consists in the constant transmission of energy. As the ship rolls, the walls of a partly filled tank induce the movement of water. Liquid sloshing phenomenon occurring in partly filled ships tanks directly affects the stability of the vessel. However, only static calculations are carried out onboard ships nowadays and static transfer of liquid weight is taken into account in the course of routine stability calculation and assessment. Since previous researches reveal the necessity of dynamic approach towards liquid movement onboard ships, the investigation is focused on problems related to time dependent wave-type phenomena. This aspect is omitted in the course of standard ship stability calculations. The set of numerical simulations of liquid sloshing taking place in moving tanks is carried out. Among many obtained characteristics, the heeling moment due to sloshing is emphasized and thoroughly investigated. The realistic range of possible metacentric heights and rolling periods is examined. The influence of ship’s rolling period on the heeling moment due to liquid sloshing is analyzed for one exemplary seagoing vessel as a case study. However, the conclusions can be generalized to some degree and comprise many other ships.

Tytuł:: An investigation into the influence of tank filling level on liquid sloshing effects onboard ships – static and dynamic approach

Opis:: The commonly discussed main features of maritime transport are usually its safety and effectiveness. One of the most critical features of seagoing ships related to her safety is stability influencing ship's overall sea keeping performance. Vessels' stability calculation and evaluation, made on-board nowadays, is based on the stability criteria published by the ship’s classification societies. According to the IMO recommendations, the righting lever curve should be corrected for the effect of free surfaces of liquids in tanks. IMO-recommended methods of free surface correction calculation consider the static attitude towards the liquid sloshing phenomenon only. They also do not consider the location of the tank within the hull of the ship and the location of a rolling axis. The more precise and more realistic approach towards liquid movement is complex analysis of liquid sloshing phenomenon. As liquid sloshing taking part in partly filled ship's tanks is an important element affecting safety of maritime transportation process, there is a need for detailed analyses related to crucial parameters of the considered phenomenon. The paper is focused on an influence of tank's filling level on effects of aroused and sustained movement of ballast water, fuel and other liquids carried onboard ships. Both static and dynamic approaches towards the problem are utilized. The analytical methods for liquid weight transfer calculation and numerical simulations of the liquid sloshing phenomenon are applied. The simulations of liquid sloshing are based on Reynolds-averaged Navier-Stockes equation and they take into account the viscosity of liquid. The resultant heeling moment is decomposed into components enabling extraction of dynamical component differentiating the applied method from old static ones. The results of the study contribute to more precise ship safety evaluation.

Opis:: According to some authors it is estimated that around 80% of accidents at sea are caused by human and organizational errors (HOE). In order to gain knowledge of phenomena that occur during ship operations, a decision was made to design and build a test site for carrying out model-based investigations of ships, including in situations of hazard to buoyancy. The model-based investigations are used as the basic and universal method for forecasting ship dynamic properties. The results of initial research on the dynamic impact of air flow on an 888 project type ship model are presented in the elaboration. The research has been executed at a test stand located in the Polish Naval Academy. The experimental results have been compared with theoretical calculations for angle of dynamic heel. Input parameters for the tests and calculations have been defined in accordance with recommendations of the Polish Register of Shipping (PRS) and International Maritime Organization (IMO) (IMO Instruments).
