Investigation of various pipe materials for riser operation in the arctic seas

А riser, which is an offshore water separation column the main difference between drilling and onshore drilling. The idea of research to calculate stressed-deformed state a riser made various materials identify technological advantages during on shelf at sea in Arctic. article result conducted Mathematica application program determine operating stresses that depend process conditions external environment. Modern technologies are designed increase capacity equipment or use alternative materials. Given pace development fields Northern Shelf Russia, there need explore for such marine as risers.
