W artykule przedstawiono wyniki badań eksperymentalnych, dotyczących współoddziaływania konstrukcji zbiornika z cieczą. Analiza ta dotyczy badań modelowych. Badanie tego zjawiska ma odniesienie do często spotykanych zdarzeń praktycznych, jak zderzenie zbiornikowca z innym statkiem lub nabrzeżem portowym, gwałtowne hamowanie cystern samochodowych lub kolejowych itp. Rozpoznanie zjawiska doprowadziło do jednoczesnych pomiarów następujących wielkości: a) wymuszanych amplitud układu generator-ciecz b) ciśnień hydrodynamicznych na ścianie zbiornika c) kształtu powierzchni swobodnych d) rozkładu prędkości cieczy w pobliżu ścianki.

The article presents The results of experimental investigations of interactions between structure tank and a liquid. The analysis is based on modelling research. The investigation of this phenomenon has direct reference to frequently recorded real events, such as collision of a tanker with another ship ora a harbour berth, rapid braking of a road or rail tanker, etc. Recognition of this phenomenon is based on simultaneous measurements of the following parameters: a) excited amplitudes of the generator-liquid system b) hydrodynamic pressures on the wall tank c) elevation of the free surface d) distribution of the velocity of water particles around the tank surface.

This paper presents methods and results of the 1st series of tests of acoustic emission (AE) signals, aimed at assessing degree of corrosion protection of a tank made of hull structural steel, protected by means of a protective coating combined from polyurethane layer and concrete filler. The tests were carried out in compliance with a method specially elaborated for application to the work in question. In the method were used requirements of the standards in force, as well as experience gained during realization of the research project CORRSHIP, included in 5th Frame Program of European Union. The application of the AE method to detect and localize corrosion sources during exposure of specimens to corrosive mixture confirmed its high usefulness for the carried-out tests on corrosion protection effectiveness of new types of protective coatings.

Greater and greater number of cargo ships sailing over small, restricted water areas can endanger the environment - in the case of disaster - by spilling fuel oil, carried in the ship’s bottom tanks for its propulsion. In this paper is proposed an alternative solution (against that of double plating) in the form of the second, elastic protective barrier which would be able to decrease risk of spilling in the case of loss of ship’s plating tightness due to collision or grounding.

Small closed sea shipping regions (such as the Baltic Sea) are specially vulnerable to consequences of ecological disasters due to spills of fuel oil used for ship propulsion and carried in single-plating double-bottom tanks. An alternative solution (against the recommended double- plating structure) was proposed. It consists in applying the second, elastic protection barrier to decrease risk of oil spills resulting from loss of tightness of ship plating in consequence of e.g. collision or grounding.
