Abstract

A sub-sea oil production system has a three-dimensional template with a framework of vertical and horizontal members. These members enclose one or more production bays each of which has a well slot and a manifold slot. Within each bay a well tree module may be installed vertically above the well slot and a manifold module vertically above the manifold slot, with a production bridge module linking them. The template and the modules are designed to be transported and installed by a semi-submersible drilling rig without the use of divers or guidelines. All access points are at the top of the modules so that the modules can be inspected, tested and serviced by a remotely operated vehicle, which can perch on raised guides on the top of hinged covers of the framework.
