Influence of convex structure on drilling riser construction

With the successful application of three-in-one technology in the domestic offshore oil field, This style technology will become more and more widely used in offshore oil development. This paper has studied the drilling riser construction under the influence of convex structure. A mechanical model for inner riser construction has been established. The method of solving restrictive thickness of the convex structure has been got. Examples are analyzed to verify the theory, and the results of the projects has a certain value in the application.
