<p>A plant comprising a post (2') with fixed sections attached thereto at various heights, and a horizontally distortable articulated pipe (3') attached to each of said sections. Other fixed sections (B'1 ... B'19) are arranged on a single level along a substantially horizontal reference line (L'). The end of each pipe is connected to a tubular column (8') extending up to the reference line. Each column is movable along the reference line and may be shifted transversely so that the columns can pass one another in the vicinity of said line. Said plant is particularly useful in the oil industry.</p> |
