| description | The invention relates to a method of installing an underwater riser. According to the method, an installation is anchored to the seabed; a tubular pipe intended to be coupled to the said installation and to be equipped with a submersible float is provided; the said float and the said pipe are then submerged, while the said float and the said pipe are held from a surface vessel; a cable is supplied and return means are installed on the said seabed installation so that the said cable can be connected to the said pipe; according to the invention, a submerged hauling buoy is attached to the said hauling cable; ballast is then removed from the float in order to compensate for the tensile forces corresponding to the weight of the said float and of the said pipe and to some of the load applied to the cable; and finally, the said hauling buoy is anchored to the said installation and the float is gradually released.
L'invention concerne une méthode d'installation d'une colonne sous-marine. Selon Ia méthode, on ancre une installation (24) sur le fond marin; on fournit une conduite tubulaire (20) destinée a être raccordée a ladite installation et a être équipée d'un flotteur immergeable (18); puis, on immerge ledit flotteur et ladite conduite, tandis qu'on retient ledit flotteur et ladite conduite depuis un bâtiment de surface; on fournit un câble (32) et on installe des moyens de renvoi (34) sur ladite installation de fond de manière a pouvoir relier ledit câble a ladite conduite; selon l'invention, on accroche une bouée de tirage (36) immergée audit cable de traction; ensuite on déleste le flotteur pour compenser les efforts de traction correspondant au poids dudit flotteur et de ladite conduite et a une partie des efforts exercés sur le câble; et, enfin, on amarre ladite bouée de tirage a ladite installation et on libère progressivement le flotteur. |
