U.S. Patent Number: 5342148

Abstract: A method and system are disclosed for establishing hydrocarbon production for offshore reservoirs in which a compliant platform is installed at a selected site, an offshore drilling vessel is docked to the compliant platform and the vessel is positioned over a selected well site for conducting drilling operations, and the production riser is transferred from the vessel to the compliant platform and secured there. Communication between a surface tree installed on the production riser and facilities supported by the compliant platform is established and these steps are repeated for each selected well site served by the compliant platform.
