Crucial issues for deep water rigid jumper design

The scope of this paper is twofold: 1) to present the FE model developed to quantify the strength and deformation capacity of induction bends subject to typical deep water installation and operational loads; 2) to describe how the Vortex Induced Vibrations phenomenon in complex 3D Subsea Rigid Jumpers can be treated to assess the fatigue damage at potential stress intensification. Both issues are pertinent to Subsea Rigid Jumper design, at the moment partially covered by specific project/company guidelines.
