Design Parameter Characteristics in a Subsea Rigid Jumper

Jung Kwan Seo, Dong Woo Kim and So Young Bae

Functionally, subsea jumpers in a short pipe connector are used to transport production fluids between two subsea components such as a tree and manifold, manifold and manifold or manifold and export sled. In the design of a rigid jumper system, all parts of the system should be analyzed with respect to reliability, safety, costs and expected failure rates and to minimize failures and maintenance for the life of the design. Rigid jumpers are standard shaped pipes that can withstand high static and dynamic loads generated by internal pressure, temperature and external fluid effects. This paper describes a fluid structure interaction modeling technique that incorporates all of the significant behavioral effects that influence the thermal and geometric characteristics of jumpers for operating, hydraulic and service fluids. The use of nonlinear finite element code allowed the creation of a jumper model of a coupled fluid structure interaction problem. The results and recommendations presented in this paper will provide assistance to the industry in the design and analysis of subsea jumpers.
