ABSTRACT:
A subsea production system for handling produced well fluids from a number of individual deep water wells drilled in different parts of a field and providing the produced well fluids to a surface production platform through a central riser. The apparatus includes a manifold section on a multi-faceted central manifold base. A plurality of booms are articulated to the manifold base at the periphery thereof, with a single boom being articulated to each facet. Each boom extends radially outward from the manifold base and has a temporary guide base and subsea tree mounted to the outer end. Extending along each boom from the manifold base is a pre-installed flow line which terminates in a connection to the tree. The lengths of the booms are alternated to provide a predetermined minimum spacing from the center of each well site to any other well site or the manifold base. Alignment of the manifold section with respect to the manifold base and hard guidance in landing the manifold section is provided by a downwardly facing, pyramid shaped funnel on the manifold and an upwardly extending pyramid shaped structure on the manifold base which is insertable in the funnel.
