Summary on Grant Application Form |
|
For a workover riser system, one of the key design issues is the requirement of top tension. The top tension is affected primarily by the riser's own wieght and current induced hydrodynamic forces. The current induced hydrodynamic forces acting on a pipe clamped with a piggyback line has not been thoroughly investigated nor is it well understood. The present design practice simply ignores the piggyback line and uses the drag coefficients derived for an isolated circular cylinder. The mean lift force due to the asymmetric orientation of the piggyback riser with respect to the current is entirely unaccounted for. It is to this end that an experimental study is proposed in this document to investigate the current induced drag and lift forces for a typical 5x2 inch workover riser configuration.
