Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mineral extraction systems face challenges in efficiently managing and diverting mud, cuttings, and natural resources during drilling operations, particularly in offshore environments, where equipment needs to be adaptable to different drilling methods and conditions, and there is a need for modular and integrated solutions to reduce complexity and maintenance.
Innovation Solution
A modular riser gas handling system that includes separable and integrated assemblies such as rotating control units, annular blowout preventers, and diverters, allowing for configuration changes based on drilling operations, and an integrated assembly that reduces height and weight, facilitating different drilling techniques and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separable and integrated assemblies are used in the riser gas handling system, then adaptability to different drilling methods is improved, but device complexity increases
Solution Approach 1:
The riser gas handling system is divided into separable assemblies including rotating control units, annular blowout preventers, and diverters. These modular components can be independently configured and reconfigured based on different drilling operations, allowing the system to adapt to various drilling methods while managing complexity through standardized modular units.
Solution Approach 2:
The integrated assembly design allows a single unified structure to perform multiple functions including rotation control, pressure prevention, and flow diversion. This multi-functional approach reduces the number of separate components needed while maintaining adaptability across different drilling techniques.
2Weight of moving object
If integrated assembly is used, then height and weight are reduced, but manufacturing complexity increases
Solution Approach 1:
Multiple functional components (rotating control units, annular blowout preventers, and diverters) are merged into a single integrated assembly structure. This consolidation reduces the overall height and weight of the equipment while the modular design within the integration maintains relative ease of manufacturing through standardized sub-components.
3Ease of repair
If modular separable assemblies are used, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The system uses separable modular assemblies that can be independently removed and maintained. Each module (rotating control unit, blowout preventer, diverter) can be serviced separately without dismantling the entire system, improving maintenance efficiency while the standardized modular interface keeps overall system complexity manageable.

AI summary
An integrated assembly for a mineral extraction system includes an annular blow out preventer (BOP) portion that includes a BOP body coupled to a first portion of an one-piece body, where the annular BOP portion is configured to seal an outer drill string of the mineral extraction system, a diverter portion formed at least partially by a second portion of the one-piece body, where the diverter portion comprises one or more openings, and a rotating control unit (RCU) assembly portion comprising a third portion of the one-piece body coupled to a rotation enabled portion, where the RCU assembly portion is configured to divert drilling fluid through the one or more openings of the diverter portion.
