The object under consideration is a semi-submersible floating drilling rig of the "Pentagon" type, located in the water area of the Sea of Okhotsk. The paper analyzes the existing types of platforms, identifies, collects, and calculates possible external loads acting on the structure, calculates the stability against overturning and shear on a flat surface when landing on the seabed and calculates the stability in conditions of floating an object with a draft of 20 m. As a result of the work, the values of the acting external loads were obtained, a conclusion was made about ensuring the stability of the structure against overturning and shear, the values of the roll and pitch angles were determined, corresponding to the permissible values of the deflection of the structure under the influence of external loads. |
