Abstract
A subsea oil and/or gas production system comprises a template having a three-dimensional framework enclosing one or more production bays, each bay having a well slot and a manifold slot. The space above the well slot is occupied by a tree module fitted with a high pressure cap. The space above the manifold slot is occupied by a manifold header module positioned on the template and forming the base of the equipment in the area of the manifold slot(s), isolation valve module(s) positioned adjacent to the manifold header module and connected thereto, flow control modules(s) positioned adjacent to the isolation valve module(s) and connected thereto, production choke module(s) positioned adjacent to the flow control module(s) and connected thereto, and production control pod(s) positioned adjacent to the flow control modules(s) and connected thereto. The tree module(s) are connected to the flow control module(s). Individual modules can be disconnected and retrieved to the surface for repair or replacement of components.
