ABSTRACT:
An apparatus and method for towing a pipeline in a body of water to a place where the pipeline is to be laid on the bed of the body of water, the pipeline having a positive buoyancy and being provided with trail-ropes distributed therealong which drag on the bed while the pipeline is being towed and maintain it at a certain distance above the bed, wherein some at least of the trail-ropes are connected to the pipeline at points spaced apart therein in such manner that such trail-ropes are formed with arcuate portions extending between the points of attachment to the pipeline so that when said arcuate portions drag upon the bed they are retained substantially parallel to the longitudinal axis of the pipeline thereby to oppose drift by a transverse current, said trail-ropes also optimally comprising means for penetrating the bed so as to offer increased resistance to drift.
