ModFlex
Advanced Modular Fabrication for Upstream Oil and Gas Infrastructure
ModFlex by Petrosmith delivers a standardized, modular approach to upstream oil and gas facility development, transforming traditional stick-built construction into installation-ready modular production systems. By integrating lean facility design with in-house engineering and fabrication, we manufacture modular tank battery systems, pressure vessels, and process equipment that accelerate project schedules, reduce field labor, improve quality control, and enhance long-term operational reliability.
Our capabilities include modular facility layout design, tank battery configuration, vessel and piping sizing, process flow diagram (PFD) development, piping and instrumentation diagrams (P and ID), fabrication drawing packages, and modular skid-mounted piping systems. Built in a controlled manufacturing environment and delivered installation-ready, ModFlex modular production facilities reduce construction risk, improve cost predictability, and provide scalable infrastructure as production requirements evolve.

Modflex benefits
Faster Construction and Installation
ModFlex reduces installation timelines by delivering prefabricated tanks, vessels, and modular skids that simplify site work and minimize the impact of weather delays and variable field conditions.
Consistent Quality Across Tanks, Vessels, and Process Systems
Indoor fabrication ensures consistent weld quality, coating performance, dimensional accuracy, and testing. Every module arrives field ready with predictable performance.
Reduced Engineering Hours and Document Control
Standardized drawing packages reduce revisions, minimize change orders, and ensure predictable engineering costs.
Improved Inventory and Material Management
ModFlex centralizes material tracking, equipment staging, and logistics coordination to reduce lost parts, late deliveries, and field rework.
Safer Construction with Fewer Onsite Exposure Hours
Modular installation requires fewer onsite welders and fitters and results in lower staffing requirements and improved jobsite safety outcomes.
Lower Operational Costs Through Repeatable Layouts
Consistent modular layouts simplify maintenance, troubleshooting, training, and long-term operation.
Modular Mobility for Extended Asset Value
Modules can be relocated and reused as production changes which extends the life and value of tanks, vessels, and modular systems.
Reduced Total Cost of Ownership
The ModFlex approach lowers capital cost and improves lifecycle performance through standardized fabrication, reduced field labor, and faster time to operation.
Modflex By Petrosmith
Delivering Installation Ready Production Systems Built for Performance
ModFlex transforms traditional oil and gas facility construction into a streamlined build strategy. Engineering, fabrication, and assembly are completed in a controlled manufacturing environment before equipment is delivered to the field as installation ready systems, enabling faster deployment and more efficient facility construction.
