ABSTRACT:
This invention provides a production riser system that enables fluid communication in a deepwater drilling environment through the use of a variable buoyancy device supporting both a hybrid riser tower and an steel catenary riser (SCR) system. Fluid communication is enabled between a surface production facility or unloading buoy and local and remote subsea (or remote non-subsea) production and export systems.
