A subsea production system that facilitates the cost effective development of offshore hydrocarbon reserves. The system includes a template base, a wellhead assembly, a saddle manifold, flowlines, a subsea tree assembly, and a control center. The system facilitates phased development by allowing control over timing for the installation of system components and by providing extendibility to additional wells developed after installation of the system.

[ What is claimed is:] [1.] A subsea template/manifold system for phased development of subsea well at a first site capable of being expanded to develop one or more additional wells at a second site, the system comprising:at least one flowline extending downwardly from a surface facility to the first well site for directing flow away from the first well site;at least one subsea wellhead;a template base having one or more receptacles capable of receiving a wellhead;a subsea tree assembly mounted on said wellhead and having a tree-to-manifold connection port;a saddle manifold mounted on said template base and having at least one production header for directing flow from said tree assembly to said flowline, said manifold also having a valve for isolating the production header from said tree assembly;said production header having (a) a first end in fluid communication with said flowline, (b) a connection providing fluid communication with said tree-to-manifold connection port, and (c) a second end; said second end being extendable to the second site without preventing a well receptacle from being able to accommodate a well; anda remote control center for controlling operation of said tree assembly.
