The vertically connected pipe jumper system consists of a pipe spool between two vertically oriented downward looking hydraulic or mechanical type connectors with metal-to-metal seals for piping connections between subsea facilities (e.g., tree to manifold, manifold to pipeline, etc.).

The actuated half of the connector is part of the retrievable jumper assembly with the mating hub attached to the subsea equipment.  The jumper connectors are landed onto upward looking hubs, made up, and tested to verify seal integrity.
