PURPOSE:To reduce the cost of manufacturing greatly by suspending a pipeline under the surface of the sea from floating members of auxiliary unit pipes with both ends closed to be airtight for disusing floaters. CONSTITUTION:Unit pipes 3 are connected in series by connecting pipes 5 for constructing a pipeline T. This pipeline T is suspended from airtight unit pipes 3' and 3'' with two ends for each closed tightly via connecting chains 7. Meanwhile, airtight unit pipes 3' and 3'' are also connected with each other by a connector 8. This construciton permits to disuse floaters specially prepared, and reduce the cost of manufacturing greatly. |
