Abstract
A method is disclosed for conducting offshore well operations from an auxiliary vessel in support of a compliant platform. The auxiliary offshore drilling vessel is docked to the compliant platform and is positioned over a selected well site for conducting drilling operations by driving the compliant platform out of alignment as necessary to bring the well operations facilities of the auxiliary vessel docked thereto into substantially vertical alignment. The production riser is transferred from the auxiliary vessel to the compliant platform after well operations are complete.
