Subsea riser system

Patent ·
OSTI ID:6474654

A subsea riser system is described for conducting petroleum or other fluid from the ocean floor to a floating loading and storage terminal or other facility at the water surface. The bottom end of the riser is connected to a subsea base by a hydraulic connector, and the lower portion of the riser is supported in tension between the subsea base and a submerged tension leg platform. The portion of the riser between the submerged platform and the floating terminal is flexible to accommodate relative movement between the platform and terminal, this flexibility accomplished by means of a series of pipe swivel joints spaced along the riser.
