Abstract

L'invention concerne un système (1) d'extraction d'hydrocarbures sous-marins comprenant cinq éléments sous-marins discrets (10, 12, 14, 16, 18) d'extraction d'hydrocarbures reliés à quatre installations de réception (2, 4, 6, 8) par un réseau de pipelines (94). Chaque élément sous-marin (10, 12, 14, 16, 18) comprend un collecteur auquel les pipelines du réseau (94) sont connectés et une paire de modules récupérables (22) installés sur le collecteur. Chaque module comporte un ensemble de régulation permettant de réguler le débit des fluides entre les éléments sous-marins et les installations de réception, et chaque ensemble de régulation est connecté à des dispositifs de surveillance afin de suivre les paramètres concernant les éléments sous-marins. Les paramètres sont suivis à un premier élément sous-marin et on identifie une condition pour un premier type de fluide et on suit les paramètres à un second élément sous-marin et on identifie un surplus concernant le premier type de fluide. Les ensembles de régulation concernés sont alors manoeuvrés afin de permettre de convoyer une quantité du premier type de fluide du second vers le premier élément sous-marin via le réseau de pipelines (94).
