THE BENDING OF A NEUTRALLY BUOYANT, TENSIONED PIPE IN A STEADY CURRENT

The stresses and flexures induced in a submerged neutrally buoyant pipe by a planar current are calculated. The pipe considered in this study is restrained at two points by a buoy-cable system which tensions that part of the pipe between the points. The points are located symmetrically with respect to the center of the pipe. The conditions that the maximum flexure and that the maximum fiber stress not exceed some specified values are then imposed. The results show that a considerable reduction in pipe diameter can be achieved by employing an untensioned pipe, to meet the specified flexure and stress requirements. This result has immediate application to the design of many oceanographic and acoustic experiments where it is desired to suspend a long horizontal array of instrumentation in the water column.
