ABSTRACT:
This invention relates to a floating production system for offshore development of oil and gas wells which employs an underwater buoy to decrease tension on flexible riser pipes used to connect a subsea pipeline to the floating vessel. The underwater buoy utilizes a cradle assembly having a drag balancing tail assembly to counteract the twisting moment applied to the cradle by current drag forces.
