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.

Abstract:
The disclosure is related to methods for testing and/or validating drill pipe and threaded and coupled connectors for use in subsea intervention system riser applications (open-water and through-riser). The methods are novel applications for testing and/or validating drill pipe and threaded and coupled connections that conform to Annex E of API 17G.
