The final qualification work of the bachelor: 47 pages., 27 ill., 8 tab., 12 sources, 6 appl. Object of the research: ice-resistant stationary platform located in the Caspian Sea. Aims of the work: evaluation the effect of external loads on the operation of the iceresistant stationary platform during operative conditions and analysis of platform stability during transport mode. For this research were used such theoretical methods as analysis, synthesis and generalization of the research results to study the properties of ice-resistant stationary platform by the effect of external loads. In the course of the work, the following external loads acting on the object were calculated: current loads; ice loads; wind loads; wave loads. Based on these calculations, the ice-resistant stationary platform was tested for overturning and shearing stableness. The calculation showed that the platform conforms the requirements for both conditions. Also an analysis of the stability of the object in transport mode was performed. A three-dimensional model was designed in AutoCad to determine righting moments under a variety of heeling angles of the platform. Based on the determined results a curve of righting moments was built; static heeling angle, dynamic heeling angle were calculated. Based on the results obtained, the ice-resistant stationary platform will be stable by the effect of external loads and will have stability in transport mode within the heeling angle from 0º to 30º. The results of this bachelor's work can be used as a structure in calculating the stableness and stability analysis of the ice-resistant stationary platforms. |
