Lawson, J

Apparatus for subsea production of fluids through a manifold and central riser from a plurality of individual wells drilled in different parts of a field in deep water, is described that is comprised of: a central manifold base having flow line connectors thereon; an elongated boom for each well to be produced in a field, each boom being rigidly attached to the manifold base; a temporary guide base mounted to the other end of each boom for establishing a well site; and a flow line extending along each boom from a flow line connector on the central manifold base. A method of producing well fluids from a number of individual wells drilled in different parts of a field located in deep water to a production platform via a central riser, which comprises the steps of: submerging to the ocean floor a subsea production apparatus which includes a central manifold base having an elongated boom for each well articulated thereto at one end and mounting a temporary guide base at the other end of the boom for establishing a well site, and a preinstalled flow line extending along each boom from the manifold base; landing a manifold section on the manifold; and landing a subsea tree on each temporary guide base.
