Title
(EN) A MOBILE OFFSHORE DRILLING UNIT AND METHOD OF CONTROLLING A PROCESS AUTOMATION SYSTEM
(FR) UNITÉ MOBILE DE FORAGE EN MER ET PROCÉDÉ DE COMMANDE D'UN SYSTÈME D'AUTOMATISATION DE PROCESSUS
Abstract
(EN)
The invention is related a floating mobile offshore drilling and a method of controlling a process automation system thereon. The floating mobile offshore drilling rig comprising a wave prediction system, a movement predictor unit, a process automation system configured to perform at least one operational sequence on board the mobile offshore drilling unit within a predetermined safe operating envelope. The process automation system is configured to enable at least one operational sequence when predicted movement of the mobile offshore drilling unit is within a predetermined safe operating envelope for the at least one operational sequence.

La présente invention concerne un forage en mer mobile flottant et un procédé de commande d'un système d'automatisation de processus associé. L'appareil de forage en mer mobile flottant comprend un système de prédiction d'onde, une unité de prédiction de mouvement, un système d'automatisation de processus configuré pour exécuter au moins une séquence fonctionnelle à bord de l'unité de forage en mer mobile à l'intérieur d'une enveloppe de fonctionnement sûre prédéterminée. Le système d'automatisation de processus est configuré pour permettre au moins une séquence fonctionnelle lorsque le mouvement prédit de l'unité de forage en mer mobile se trouve à l'intérieur d'une enveloppe de fonctionnement sûre prédéterminée pour l'au moins une séquence fonctionnelle.
