DOI: https://doi.org/10.37890/jwt.vi77.452

Abstract

The paper considers the effect on water resistance of the movement of a semi-submersible floating crane model on quiet deep water in working and transport positions and different heading angles. The research was conducted in the experimental pool of Sevastopol State University. The performed towing tests of the model made it possible to plot the dependence of the coefficient of impedance on the Froude number. Each of the presented graphs refers to a certain horizontal clearance and heading angle, as well as the number of intermediate stabilization columns. According to the obtained graphs, it is possible to estimate the power of the power plant, mainline and shunting engines of a semi-submersible floating crane of the selected design scheme at the initial stages of design. In the future, it is planned to carry out research to determine the coefficient of additional resistance from the excitement of the considered cases of the hull shape.

Keywords: crane vessel, double-hulled semi-submersible vessel, model tests, instruments, experimental pool, water resistance, similarity criteria, resistance coefficient
