Sažetak
Modern container ships are designed to meet the requirements of increased capacity and to achieve high speed, whereby causing a relatively low block coefficient. Due to such features, they become
most susceptible to the impact of parametric rolling. In addition to the structural features of the ship, parametric rolling is also affected by characteristics of successive waves either from the fore or aft
part. The appearance of parametric rolling can threaten the people on board, the ship and her cargo. Therefore, the IMO has been actively involved in providing support for study of this phenomenon. The systems, which are used for prevention and mitigating the consequences of ship’s parametric rolling, can be regarded as systems for monitoring the characteristics of waves and those of the ship that have an effect on the occurrence, and also as systems seeking to reduce ship’s rolling that occurs as a consequence of the observed phenomena.
The aim of this paper is to define the characteristics of container ship, and the characteristics of waves that directly affect the appearance of ship’s parametric rolling. The paper also analyzes technical
solutions that can be used to obtain data relevant for the development and technical solutions which may reduce the effect of the phenomenon.
