Textured deep subsea pipelines

In contrast to a conventional cylindrical pipe, a textured pipe is proposed for deep subsea operations. The basic geometric parameters, the stiffness properties and the stress distribution in the textured pipe are presented. The propagation buckling response of the textured pipe is analysed and compared to equivalent cylindrical pipe. The effects of geometric imperfection and the basic geometric parameters defining the textured pipe on the propagation response are evaluated. The textured pipe offers a substantial increase in propagation buckling capacity when compared to equivalent cylindrical pipe.
