Abstract
An articulated riser including at least two framed structures comprised of a plurality of fluid-handling lines connected by multiple fluid-handling line flexible joints. The articulated riser of the present invention provides a system wherein fluid-handling lines may be connected between a structure on the subsea bottom and a floating vessel either for the production of crude oil and natural gas offshore, or for the operational functions before or after producing a subsea well, or any combination thereof. The articulated riser of the present invention may extend to a foundation structure situated on the subsea bottom or to an upright self-standing riser, providing a manifold for a plurality of fluid-handling lines to be connected to a floating vessel. Means may be provided for either partially or substantially totally providing buoyancy for the articulated riser.
