METHOD AND APPARATUS FOR ATTACHING PIPELINES TO OFFSHORE STRUCTURES

摘要

A pipe guidance system is attached to an offshore structure. A remote pipe guide connected to a pipeline being laid underwater is pulled to and properly positioned adjacent the offshore structure by means of the pipe guidance system. A riser pipe is guided to a position for connection to the pipeline by means of a riser guide which is also attached to the offshore structure. Then the pipeline and riser pipe are connected together. The pipe guidance system includes at least one pulley connected to the offshore structure and a cable arranged about the pulley. One end of the cable is connected to power means for applying a pulling force on the cable and the other end is connected to the pipe guide.
