Abstract

A lean-to well protector apparatus for use on offshore wells having a generally vertical upstanding conductor pipe extending between the sea bed and the water surface includes a pair of jacket legs defining a plane that is angularly oriented with respect to the conductor pipe forming an acute angle therewith. A first plurality of structural chord members interconnects the jacket legs and can occupy the plane defined by the jacket legs. The first plurality of chord members and the jacket legs form a truss that leans towards the conductor pipe during operation of the offshore well. A first clamp connector is positioned at the middle portion of the conductor pipe and a second clamp connector is positioned at the upper portion of the conductor pipe generally near the water surface area. A second plurality of structural chord members interconnects the conductor pipe with the truss at the clamp connectors. At least some of the plurality of structural chord members extends between the truss and the first and second clamp connectors. The apparatus thus uses the conductor pipe as one of the legs of a structural assembly for protecting offshore oil wells.
