Riser Design

Abstract

The general elements and step‐by‐step procedure for designing riser systems will be described. The variety of configurations of subsea riser systems is broad, and thus, the detailed design procedure must adapt to the specific issues. Every element covered in this article should nonetheless be considered all for all types of risers. The concept of a global riser analysis is presented. Key failure modes are listed along with failure criteria. The key design parameters are numerous, and thus, with any open‐ended problem, the design procedure can be iterative and fraught with missteps. A rational step‐by‐step design procedure is shown to help ensure a straightforward process with minimal iterations.

“…For each state of wave surface elevation, the associated horizontal velocity and acceleration of the water particles are determined from the basic wave theory [35]. Assuming an one-dimension sea where all waves are running in the same direction, the horizontal water velocity (u) and acceleration (a) in the direction of wave propagation are given at an elevation (z) by the equations:…”
