Abstract
(EN)
A subsea well intervention method implemented on a well (200) from a floating vessel (100), said floating vessel not comprising a derrick, the method comprising a step of connecting a power line (207) directly between a remotely operated vehicle (206) and the blowout preventer module (202) for powering the blowout preventer module, the remotely operated vehicle (206) being connected to a control unit (107) located on the floating vessel via a remotely operated vehicle umbilical (106).
(FR)
L'invention concerne un procédé d'intervention sur puits sous-marin, mis en œuvre sur un puits (200) à partir d'un navire flottant (100), ledit navire flottant ne comprenant pas de derrick, le procédé comprenant une étape de connexion d'une ligne électrique (207) directement entre un véhicule télécommandé (206) et un module de bloc obturateur de puits (202) permettant d'alimenter le module de bloc obturateur de puits, le véhicule télécommandé (206) étant connecté à une unité de commande (107) située sur le navire flottant par l'intermédiaire d'un câble ombilical de véhicule télécommandé (106).
