A subsea production system and method includes a wellhead field having multiple wellheads and utilizes a stackable guide funnel system for sequential tying back of those wellheads. A storage frame retains several guide funnels that are nestably stacked one upon the other. The frame is made up of a plurality of guide members that are secured to the exposed tubular conductor of a wellhead. A pair of annular rings surrounds portions of each of the guide members. A riser having a riser connector is lowered to the central location. The riser connector latches onto the uppermost guide funnel within the frame. The riser, together with the affixed funnel, is then lifted upwardly, removing the affixed funnel from the frame. The riser is then moved laterally through the sea until the funnel and riser are proximate a second wellhead within the wellhead field.
