Abstract
Abstract Buoyant bodies such as those used for drilling oil and gas wells in water-covered areas are moored to the floor of the body of water with lines in the catenary configuration. Rotational motions induced by such configurations are reduced by providing for vertical adjustment in the point of attachment of the lines on the buoyant body.
