The paper will address a spools & jumpers sizing methodology and present an innovative design tool. Spools and jumpers are used subsea to connect subsea Trees to Manifolds or to Flowlines. The analysis of the spools and jumpers requires a large number of calculations to be performed at each stage of the spool design process: 1. Preliminary phase: Screening of several types of geometry in a large number of configurations (shortest & longest geometry for different types of soils and sensitivities) to gather the spools in groups corresponding to specific types of geometry. 2. Detailed phase: Within each group, all the spools are verified in their specific configuration, for all the potential misalignment cases and during all the potential operating phases (Stroking, hydrotest, operation, shutdown). Therefore, when designing a large number of spools and jumpers, the number of calculations to be performed can be extremely time consuming.
