Variation of Hydrodynamic Load on Vertical Riser
Abstract: The main purpose of risers on offshore structures is to transport hydrocarbon from the reservoir to the topside. Vertical risers are usually made of steel and vertically attached to the main structure at specific locations. In this paper, the variation of hydrodynamic load on a fixed vertical riser is studied. The main force experienced by the riser is the drag force since the riser is made of a small diameter tubular member. The largest horizontal force on the riser with a diameter of 14 inches is found to be 22.5 kN at an elevation of 76 m. Time variation effects on riser von-Mises stresses were variation was also investigated. Maximum von-Mises stress is 54 MPa on element 90 at the mean water level.
Keywords: jacket structure, fixed verticalriser, hydrodynamic load, riser deformation, von-Mises stress
