Experimental assessment of critical stability parameters related to wave height

In the period of 1992-94 the team of Ship Hydromechanics Division, Technical University of Gdańsk carried out experiments with the free runnig ship model on the lake in various weather conditions. The aim of the model tests was to collect information about ship capsizing related to significant wave height and various stability parameters. The procedure of carrying out the investigations is described. Stability criteria in function of the wave height were established onthe basis of the experimental results. Compliance with the proposals is expected to protect the ship against capsizing at sea if the wave conditions are known.
