PROCESS AND DEVICE FOR LAYING SUBMARINE PIPELINES

摘要

A method and apparatus are provided for positioning an underwater pipeline. The pipeline is initially buoyant and a force distribution cable is used. This cable extends over the full length of the submerged part of the pipeline and is attached to the pipeline hangers. The hangers can be used in conjunction with heavy chains acting as guide ropes and anchoring blocks and a further cable attached to the head of the pipeline transmits a part of the haulage force directly to the pipeline.
