The purpose of the work is to study the behavior of a jack-up rig during operation at a given point in the water area, taking into account the action of the current, wind and waves using mathematical modeling, as well as checking the conditions for safe operation of the jack-up rig in extreme conditions. The work analyzed the external conditions of the staging area, considered the basic design features of the jack-up rig. The introduction of jack-up jack supports into the bottom soil was simulated, and the behavior of the platform during its operation under the influence of external forces was studied. In parallel, the safety factors for rollover, subsidence and shift of the support feet were found when the jack-up drill was on the bottom soil. |
