The purpose of the final qualification work is to calculate the loads on a self-lifting floating installation; calculate the stability of the structure for tipping and flat shear; calculate and compare the stability of the platform at the stage of storm sludge and at the stage of towing. With the help of theoretical information, in this bachelor's work, the properties and behavior of a self-elevating drilling rig were studied under the influence of external loads from wind, ice, currents and waves. In the process of work, the following studies were performed: 1. The external loads from ice, wind, currents and waves acting on Self-propelled floating drilling platform are determined. 2. Calculation of the stability of the Self-propelled floating drilling platform from the action of external loads on capsizing and shear. 3. The stability of the platform was calculated for the case when a storm caught it at the towing stage (storm sedimentation stage with an estimated draft of 15 m). The results of the final qualification work can be used to justify the choice of the Uranus self-elevating drilling rig in certain climatic conditions of the construction site. Based on the results of the above studies, it was concluded that the goals were achieved. This offshore platform will operate normally during its entire service life. It will be able to bear the storm that caught it at the towing stage, and will remain stable under the action of the specified loads from the wind and the current. Calculation of loads was carried out on the basis of current norms and rules. |
