COMPRESSOR STATION EXPANSION
Designing for future plug & play
LOCATION: Wyoming
MARKET: Natural Gas Gathering
THE CHALLENGE:
Growing gas production necessitated our client expand one of their compressor stations, doubling the capacity and total installed horsepower. The original low-pressure inlet was updated to allow for multiple inlets to feed gas compression and dehydration. The high-pressure inlet was modified to allow for blending should it need additional dehydration. Late into execution of the project, the existing high-pressure 3-phase separator was upsized to improve liquid removal and dehydration performance.
THE EXECUTION
Develop a Plan
• Executed onsite visits and as-built documentation of existing facility
• Reviewed operational improvements for the expansion
• Developed design basis to capture required project technical requirements
Source New Equipment
• Low-Pressure Inlet Slug Catcher
• High-Pressure 3-Phase Separator
• Motor Control Center (MCC) Expansion
Execute Value Engineering to Support the Project Schedule
• P&ID generation
• Equipment evaluation
• PSV sizing calculations and safety review
• Engineered Valve specification
• 3D modeling
• Construction packages for electrical, mechanical, and civil bids
THE SOLUTION
Engineering
✓ Up-to-date engineering package for the site
✓ Future compressor additions require no additional mechanical design
✓ Developed plan for short shutdown window for tie-ins
Operations
✓ Addressed issues with high-pressure drains to VRU
✓ Improved isolation and access to compressor packages
✓ Consolidated planned equipment for a two-inlet design to a single inlet
