| 发明名称 | Method of abandoning an underwater pipeline on the bed of a body of water | ||
| 摘要 | A method of abandoning an underwater pipeline on the bed of a body of water from a laying vessel includes the steps of lowering the free end of the pipeline into the body of water and onto the bed of the body of water using a first and second rope, both connected to the free end of the pipeline and extending from the laying vessel to the free end of the pipeline. The method also includes disconnecting the first rope from the free end of the pipeline, once the free end of the pipeline is laid on the bed of the body of water; and rewinding the first rope onto the laying vessel, while the second rope is still connected to the free end of the pipeline. | ||
