description: Objective: development and optimization of system of deduction of the semisubmersible drilling rig for the modes of operation and survival on the set water area point. In the real work limit wind-wave conditions for the set water area are defined; the restrictions set on linear and angular movements of the platform in the modes of operation and survival are analyzed. Besides, within work the research of behavior of PPBU under the influence of wind, currents and disorders is conducted by methods of mathematical modeling by results of which optimization of the chosen system of deduction has been performed. Specification of extreme parameters of external influences at which safety of the platform in the modes of operation and survival is ensured is also executed. At the end of work conclusions are drawn on the most suitable parameters of system of deduction of semisubmersible installation in the set point of statement necessary for ensuring safe functioning in the modes of operation and survival.
