Modular Hydraulic Pumping Unit for Well Site Footprint Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hydraulic fracturing fluid pumping units are cumbersome, difficult to maneuver, require special permits for transport, and are complex and costly to operate, monitor, and repair due to their large size and weight.
Innovation Solution
A mobile hydraulic fluid delivery system with a modular design featuring a chassis with quick-release sub-assemblies for the power, pump, and cooling systems, allowing for easier transportation, maintenance, and reduced equipment footprint, including a towable platform with a power sub-assembly, pump sub-assembly, and cooling sub-assembly that can be easily detached and reattached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional trailer or skid mounted hydraulic fracturing fluid pumping units are used, then the system can provide high pressure fluid delivery capability, but the units become quite long and difficult to maneuver at well sites
Solution Approach 1:
The pumping unit is divided into separate functional modules (power module with engine and transmission, pump module with high pressure pump, cooling module with radiators) that can be independently positioned on the chassis. This segmentation allows each module to be optimized for compactness while maintaining overall system functionality, reducing the total length and improving maneuverability at well sites
2Weight of moving object
If traditional trailer or skid mounted hydraulic fracturing fluid pumping units are used, then the system can provide high pressure fluid delivery capability, but the weight requires special operating permits for transport
Solution Approach 1:
The system is segmented into separate modules that can be independently secured to the chassis. This modular architecture allows for optimized weight distribution across the chassis frame, enabling the use of smaller, more maneuverable vehicles that fall within standard transportation weight limits, thereby eliminating the need for special operating permits
Solution Approach 2:
The modular design allows the configuration and weight distribution of the system to be dynamically adjusted by repositioning or removing specific modules based on operational requirements. This flexibility enables the system to meet varying transportation regulations without sacrificing core functionality
3Device complexity
If traditional trailer or skid mounted hydraulic fracturing fluid pumping units are used, then the system can provide high pressure fluid delivery capability, but the complex design renders the units difficult and expensive to operate, monitor, and repair
Solution Approach 1:
By segmenting the pumping unit into distinct functional modules (power, pump, cooling), each module can be designed, tested, and maintained independently. This reduces overall system complexity as each module has fewer components and simpler interconnections, making operation, monitoring, and repair more straightforward and cost-effective
Solution Approach 2:
The modular design allows individual modules to be easily extracted from the chassis for maintenance or repair without affecting the other modules. This extraction capability simplifies repair operations by isolating the problematic component, reducing downtime and maintenance costs while maintaining the high pressure fluid delivery capability of the overall system

AI summary
The application is directed to a system and method for hydraulic fluid delivery including the delivery of high pressure fluid in hydraulic fracturing operations. The system of this application is operationally configured to reduce the footprint at a well site and, in one aspect, includes a towable platform carrying a power sub-assembly, a pump sub-assembly and a cooler sub-assembly each of which is releasably attachable to the platform. Each sub-assembly may be removed from the platform without disturbing the relationship between the platform and the remaining sub-assemblies attached thereto.
