Abstract
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.
