ONEOK Rockies Midstream, LLC – Compressor Station Program

Share Project:

Corval Group began working with ONEOK as a General Contractor on small projects, Today the relationship has grown into a $500 Million EPC program spanning over 19 compressor stations.
The Bakken is a resource-constrained area – the climate is harsh and materials are expensive. Corval implemented a proprietary product or ONEOK and cut overall construction-to-facility commissioning time by 25%. Corval’s relationships and overall experience evolved from a General Contractor to EPC Solutions Provider.
As Corval’s relationship with ONEOK developed we continued to seek better ways to deliver projects. Our EPC Team successfully worked with ONEOK Partners to provide multiple stations under some of the harshest conditions, and with aggressive timelines. Each facility was engineered, constructed, procured and commissioned in about (8) months. Corval became the preferred partner offering for Engineering, Procurement, Construction and Commissioning of each facility and all associated infrastructure, with a contract structure incorporating complete cost visibility and shared risk.
Corval supported ONEOK’s station objectives with a proactive team approach. Corval Group provided the engineering, site civil construction, process piping, electrical and controls, and sets all major equipment.
