Dynamic Component of Ship’s Heeling Moment due to Sloshing vs. IMO IS-Code Recommendations

Krata P.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2010

Vol. 4, no. 3

363--368

The comparative study of the dynamic component of heeling moment due to sloshing in ships’ partly filled tanks is presented in the paper. The characteristics of heeling moment are obtained in the course of experimental tests and numerical simulations. The heeling moment is decomposed and the research is focused on the dynamic component resulting from liquid movement. The results of the research are compared to the computations performed in accordance with the IMO IS-Code recommendations. The need for amending of the intact ship stability assessment procedure is suggested.

Model of Interaction of Water and Tank’s Structure in Sloshing Phenomenon

Krata P.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 4

389--395

The paper presents the model of interaction between ship’s tank structure and water contained in the tank. The experimental investigation of sloshing loads in ships’ tank is characterized and the need for description of mutual influence is underlined. The model of interaction is made up for rectangular ship’s tanks and it is assumed to be in time-domain and nonlinear. The solution is based on the data obtained by the experimental research and numerical simulation. The study may be the contribution to more sophisticated estimation of ship’s stability than it takes place nowadays.
