Abstract
A seabed flowline is connected to a substantially conventional tanker serving as a floating storage facility by a system comprising a three-leg mooring and a flexible riser. The mooring comprises anchors connected by anchor risers to a common node, and a mooring pendant extending from the node to the tanker. The flexible riser comprises a flexible rubber hose extending from the seabed to the tanker, and a single rotational coupling. The hose has a top section secured along part of the mooring pendant, and an intermediate section provided with buoyancy and restrained by a tether to maintain it clear of the anchor risers.
