The Challenge
Growing gas production necessitated our client expand one of their compressor stations, doubling the capacity and total installed horsepower. The original design of the low-pressure inlet was originally designed for two slug catchers, leading to concern over liquid management onsite. The high-pressure inlet did not allow for blending for dehydration optimization. Late into execution of the project, the existing high-pressure 3-phase separator was upsized to improve liquid removal and dehydration performance.
The Solution
Developed a plan and budget:
- 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 Results
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 single inlet
