Summary:In subsea drilling operations, workover control systems may include deployment of an umbilical from a deepwater drilling vessel. Such an umbilical provides support functions for deepwater drilling operations. In the practice of the invention, a new method, system and apparatus may be employed to deploy the umbilical independently of the drilling riser, which provides commercial and operational advantages. That is, the umbilical may be deployed at a different time than the riser is deployed, and also without intimate close connection from the umbilical to the riser. Dans les opérations de forage sous-marines, les systèmes de commande de reconditionnement peuvent comprendre le déploiement d'un ombilical à partir d'un réservoir de forage en eaux profondes. Cet ombilical fournit des fonctions de service pour les opérations de forage en eaux profondes. Dans la mise en oeuvre de l'invention, une méthode, un système et appareil nouveaux peuvent être utilisés pour déployer l'ombilical indépendamment de la colonne montante de forage, ce qui offre des avantages commerciaux et fonctionnels. C'est-à-dire que l'ombilical peut être déployé à un autre moment que la colonne montante, et également sans liaison très étroite entre l'ombilical et la colonne montante.
