ABSTRACT:
A shoe for adjustably supporting a pipeline relative to a ramp of a lay vessel is comprised of a cradle which supports the pipeline in longitudinally movable relation with the ramp. The cradle contacts the pipeline intermediate the longitudinal axis of the pipeline and the surface of the ramp. An elongated lever is pivotally connected at one extreme to the ramp and at another extreme to the cradle. The elongated lever is rotated by rotating means about the pivotal connection with the surface of the ramp to alternately raise and lower the cradle and thereby adjustably support the pipeline relative to the ramp.
According to the method of the invention, a pipeline can be adjustably supported relative to a ramp of a lay vessel by first cradling the pipeline above the surface of the ramp in longitudinally movable relation therewith. This step may be accomplished by a cradle having two degrees of freedom relative to the ramp and pivotally connected thereto through an elongated lever. The cradle can be raised or lowered to adjustably support the pipeline relative to the ramp of the vessel by rotating the elongated lever.
