BOP Control Integration Using Rig Data for Drawworks Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing well construction systems lack effective communication and data integration between the rig control system and the blowout preventer (BOP) control system, leading to suboptimal control of BOP equipment and potential damage due to limited sensor data availability.
Innovation Solution
A system is introduced that integrates a pressure control system, a BOP control system, and a rig control system, enabling communication and data sharing between them. The BOP control system includes sensors for operational status and a human-machine interface (HMI) to monitor and control BOP equipment, while also receiving data from the pressure and rig control systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the BOP control system operates independently with limited sensor data, then the system complexity is reduced, but the control optimization and operational efficiency deteriorate
Solution Approach 1:
The patent merges the BOP control system with the rig control system by establishing communicative connection between them. This allows the BOP control system to access rig sensor data and implement optimized control strategies based on comprehensive wellbore conditions, thereby improving operational efficiency without significantly increasing overall system complexity.
Solution Approach 2:
The BOP control system is enhanced with multi-functionality by enabling it to not only control BOP equipment but also to receive and process data from both BOP sensors and rig sensors. This universal data access capability allows the system to optimize control decisions based on comprehensive information from across the entire drilling operation.
2Reliability
If the BOP control system accesses comprehensive sensor data from rig and pressure control systems, then the control optimization improves, but the device complexity increases
Solution Approach 1:
The patent introduces a communication interface as an intermediary between the rig control system and the BOP control system. This intermediary enables data exchange and integration, allowing the BOP control system to access comprehensive sensor data from rig and pressure control systems while maintaining modular system architecture and avoiding excessive complexity increase.
3Ease of operation
If limited sensor data is used for BOP control, then the ease of operation is improved, but the risk of suboptimal control and equipment damage increases
Solution Approach 1:
The patent implements comprehensive feedback mechanisms by enabling the BOP control system to receive real-time sensor data from both BOP sensors and rig sensors. This feedback loop allows the system to continuously monitor wellbore conditions and adjust BOP control decisions accordingly, improving equipment safety while maintaining ease of operation through automated control.

AI summary
A system includes a rig control system for controlling rig equipment operable to perform drilling operations to drill a wellbore at a wellsite, and a blowout preventer (BOP) control system for controlling BOP equipment that is communicatively connected with the rig control system. The rig equipment includes a drawworks for conveying a drill string, at least one sensor operable to output rig data related to the rig equipment, and a rig control workstation to monitor and control the rig equipment. The BOP control system includes at least one sensor operable to output BOP data indicative of operational status of the BOP equipment. When the BOP data indicates that the BOP equipment is closed, the rig control system is operable to display on the rig control workstation information indicative of the BOP equipment being closed, and limit use of the rig control workstation to operate the drawworks.
