Application of Method of Statistic Testing in the Task of Load Lifting ‎from Deep Depth in Conditions of Random Sea State ‎

Sukhorukov A.L.

Nowadays, with account of depletion of hydrocarbon raw materials onshore there is a tendency to develop ‎deep oil and gas fields. In course of development of the fields, significant amount of various lowering-and-‎hoisting operations are fulfilled. The task of determination of the forces in load lifting from deep depth in the ‎conditions of random sea state is solved on the basis of statistic testing method (Monte Carlo method). Math-‎ematical model took into account non-linearities caused by jerking and non-linearities of forces of the load ‎hydrodynamic resistance. Comparison of the results with relevant solutions of linear tasks has been made.
