<p>A pipeline laying operation wherein a continuous pipeline bundle comprised of a plurality of conduits is payed out from a floating vessel onto a submerged surface under the control of a tensioned flexible cable. The conduits are strapped to an alignment and spacer member at a plurality of longitudinally spaced bundling zones. The cable, the spacer and the pipeline bundle are placed in a force transmitting relationship, i.e., the weight of the pipeline bundle is transmitted to the cable at the spacer locations. Tension is applied to the cable at the floating vessel, to react the applied pipeline bundle weights at the spacers, maintaining the pipeline bundle conforming to a chosen configuration, which will keep the pipe stresses within a given level. Feed paths, defined by roller assemblies, for each of the conduits on the vessel maintain the end portions of the conduits laterally spaced and induce convergence of the conduits toward a bundling station.</p> |
