Brownfield Modifications
& Management of Change (MOC)
Engineering and execution of facility retrofits, upgrades, and brownfield modifications.
- Overview
Engineering and execution of facility retrofits, upgrades, and brownfield modifications.
Gas Liquids Engineering (GLE) provides engineering and project execution services for facility retrofits, debottlenecking programs, and Management of Change (MOC) modifications across oil, gas, liquids processing, and industrial facilities.
Operating facilities must continually evolve to meet changing production requirements, regulatory standards, and operational improvements. GLE has extensive experience executing modifications to existing facilities — ranging from small equipment replacements to major brownfield expansions — while maintaining safe operations and minimizing disruption to ongoing production.

Brownfield Facility Modifications
GLE regularly executes retrofits and upgrades within operating facilities including gas plants, oil batteries, fractionation facilities, terminals, pipelines, compressor stations, and industrial processing plants. These projects often involve integrating new process equipment, modifying existing systems, or upgrading facility infrastructure while maintaining safe and reliable operation of the plant.
- GLE's experience with existing facility layouts, tie-ins, and operating constraints allows retrofit projects to be executed efficiently and safely.
- Management of Change
Management of Change (MOC) Projects
GLE frequently supports clients with engineering for Management of Change (MOC) projects, ensuring facility modifications are implemented safely and in compliance with regulatory and operating requirements.
MOC projects often involve targeted changes to equipment, piping, instrumentation, or operating systems that improve safety, reliability, or performance of existing facilities. Typical MOC work includes:
- Process and piping modifications
- Pressure protection system upgrades (PSVs, ESDVs)
- Control system changes and automation upgrades
- Equipment replacements and system upgrades
- Tie-ins for new wells, pipelines, or process equipment
- Regulatory compliance upgrades
- GLE works closely with facility operators to develop modifications that are practical, constructible, and compatible with existing plant systems.
- Optimization
Debottlenecking & Capacity Improvements
Many retrofit projects focus on improving facility throughput, reliability, or energy efficiency. GLE routinely evaluates operating facilities to identify opportunities for:
- Project Execution
Efficient Brownfield Project Execution
Retrofit projects require careful planning to minimize facility downtime and operational risk. GLE develops detailed engineering packages and construction strategies that allow modifications to be completed efficiently, often during short outage windows.
Our multidisciplinary engineering teams coordinate process, mechanical, electrical, instrumentation, controls, and drafting activities to ensure modifications integrate smoothly with existing facilities.

- Procurement Assistance
- Regulatory Coordination
- Construction & Commissioning
- Execution Capability
Proven Track Record
GLE has executed thousands of projects across Western Canada and internationally, ranging from small facility upgrades to large-scale brownfield expansions. Our teams regularly work within operating facilities where safety, constructability, and operational continuity are critical considerations.
With extensive experience in gas processing, liquids facilities, fractionation plants, pipelines, terminals, and industrial energy systems, GLE delivers retrofit and MOC projects that improve performance, reliability, and long-term operability of existing facilities.
