<p>A hybrid riser tower is disclosed with a rigid riser column and a buoyancy tank positioned to apply tension to the riser column by buoyant upthrust when the tower is in an upright orientation for use. At least one jumper support structure is attached to a side of the buoyancy tank between upper and lower ends of the buoyancy tank when the tower is oriented for use. At least one riser connection extends outside the buoyancy tank from a riser pipe of the riser column to the jumper support structure, where it connects to a flexible end fitting carried by the jumper support structure. The riser connection splays laterally moving from the riser pipe toward the jumper support structure.</p> |
