Diverless hard-pipe connection systems for subsea pipelines and flowlines
Hard-pipe tie-in jumpers, for diverless subsea connections between production manifolds and export pipelines (or satellite wells), are an economical alternative to traditional diverless connection methods life deflection and pull-in; and also to flexible pipe jumpers. A systems level approach to the design of the jumpers, which takes into consideration performance requirements, measurement methods, fabrication and installation constraints, as well as code requirements, is essential to making these connections economical and reliable. A dependable, ROV-friendly measurement system is key to making these connections possible. The parameters affecting the design of hard-pipe jumpers, and the relationship between these, are discussed in the context of minimizing cost while maintaining reliability. The applicability of pipeline codes to the design of hard-pipe jumpers is examined. The design, construction and installation of the Amoco Liuhua 11-1 pipeline tie-in jumpers are presented as a case study for applying these concepts.
