A submarine pipeline being laid from a barge forms an "S" curve from the barge to the ocean floor, of which the lower part is the sag-bend (Abstract No. 19-50465) and the upper part the over-bend. Control and support for the over-bend must be provided from the barge. For shallow water a long straight support called a "stinger" is sufficient, but as depth increases, the stinger is modified to fit the curvature of the over-bend, perhaps by articulation of a segmented stinger, and the need for an excessively long stinger is reduced by providing tension on the lay barge. Analysis of the interaction between the buoyant stinger and the tension system reveals that tension must support only the vertical component of the suspended pipe weight. The barge positioning system provides the anchoring forces that ultimately produce the horizontal tension in the pipe.
