Title
(EN) METHOD FOR LAYING AND/OR RECOVERING A FLEXIBLE LINE IN A BODY OF WATER AND ASSOCIATED SYSTEM
(FR) PROCÉDÉ DE POSE OU/ET DE RÉCUPÉRATION D'UNE LIGNE FLEXIBLE DANS UNE ÉTENDUE D'EAU ET SYSTÈME ASSOCIÉ
Abstract
(EN)
The method comprises at least one phase of quasi-immobilisation or immobilisation of the line comprising the following steps: - activating the motor (110) of at least one upper tensioner (72A) and/or of at least one lower tensioner (72B) by means of a control unit in order to apply a torque for retaining the line against its own weight to the movement member of the upper tensioner (72A) and/or of the lower tensioner (72B); - at least spot controlling, by means of the control unit, at least one motor (110) of an upper tensioner (72A) and/or of a lower tensioner (72B) in order to move a movement member of the upper tensioner (72A) and/or of the lower tensioner (72B) or to modify the retaining torque applied to the movement member of the upper tensioner (72A) and/or of the lower tensioner (72B).

Procédé de pose ou/et de récupération d'une ligne flexible dans une étendue d'eau et système associé Le procédé comporte au moins une phase de quasi-immobilisation ou d'immobilisation de la ligne comportant les étapes suivantes : - activation du moteur (110) d'au moins un tensionneur supérieur (72A) ou/et d'au moins un tensionneur inférieur (72B) par une unité de commande, pour appliquer sur l'organe de déplacement du tensionneur supérieur (72A) ou/et du tensionneur inférieur (72B), un couple de retenue de la ligne à l'encontre de son poids; - pilotage au moins ponctuel par l'unité de commande d'au moins un moteur (110) d'un tensionneur supérieur (72A) ou/et d'un tensionneur inférieur (72B) pour engendrer un déplacement d'un organe de déplacement du tensionneur supérieur (72A) ou/et du tensionneur inférieur (72B) ou pour modifier le couple de retenue appliqué sur l'organe de déplacement du tensionneur supérieur (72A) ou/et du tensionneur inférieur (72B).
