Abstract

A method for conducting offshore well operations is disclosed in which a compliant platform is restrained out of its normal position substantially over a well pattern by adjusting a first lateral mooring system connecting the compliant platform to a first array of anchors secured to an ocean floor. An offshore drilling vessel is then positioned over a selected well site of the well pattern at a location at the surface of the water not accessible to the offshore drilling vessel with the compliant platform in its normal position by adjusting a second lateral mooring system connecting the compliant platform to a second array of anchors on the ocean floor. Well operations are then conducted through a substantially vertical riser while maintaining a clearance to prevent direct contact between the compliant platform and the offshore drilling vessel.
