Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and expense of subsea hydrocarbon well operations are increased by the need for separate control systems and dedicated control lines for blowout preventers and telemetry systems, which can complicate communication between subsea and surface systems.
Innovation Solution
A subsea control and telemetry system that integrates a wireless telemetry system with a blowout preventer system, using acoustic or electromagnetic repeaters along the wellbore to relay control signals and data through a common umbilical, eliminating the need for separate telemetry cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control systems and dedicated control lines are used for blowout preventer and telemetry systems, then system reliability and control precision are improved, but device complexity and expense increase
Solution Approach 1:
The patent combines the blowout preventer control system and telemetry system into a single integrated system. The control head at the subsea location handles both BOP control functions and telemetry data acquisition/ transmission functions, eliminating the need for separate control systems and reducing overall system complexity while maintaining operational reliability
Solution Approach 2:
The control head is designed as a multi-functional device that performs both BOP control operations and telemetry data handling. This universal device consolidates previously separate functions into one unit, reducing the number of components needed while ensuring both control and telemetry operations can be performed reliably
2Reliability
If separate dedicated control lines and umbilicals are deployed for blowout preventer and telemetry systems, then communication reliability is improved, but installation complexity and cost increase
Solution Approach 1:
The patent merges the control line and telemetry cable into a single integrated umbilical connection. The control head receives both control signals and telemetry data through one unified communication interface, simplifying the deployment process while maintaining communication reliability through dedicated functional channels within the integrated system
3Adaptability or versatility
If multiple separate cables and control lines are routed from subsea to surface, then system functionality is improved, but expense and operational complexity increase
Solution Approach 1:
The integrated control and telemetry system enables a single umbilical to perform multiple functions - both BOP control and telemetry data transmission. This multi-functional approach maintains full system functionality while eliminating the need for multiple separate cables, thereby reducing deployment complexity and expense

AI summary
A technique facilitates communication in a subsea well application. The technique involves deployment of a blowout preventer subsea control and telemetry system to a subsea location proximate a wellbore. The blowout preventer subsea control and telemetry system is coupled to both a blowout preventer system and a wireless telemetry system. The wireless telemetry system has a plurality of repeaters deployed along the wellbore. The blowout preventer subsea control and telemetry system is used both to collect data from the wireless telemetry system and to control operation of the blowout preventer system. For example, the blowout preventer subsea control and telemetry system may receive control signals from a surface system and also relay data to the surface system through a common communication line.
