For over 40 years, we have built large capital projects in the refining sector, including work on all major process units and technologies, comprised of new greenfield and brownfield capacity additions, environmental upgrades, revamps/modernizations, and feedstock flexibility conversions. Most of this work has occurred within operating facilities and included complex turnaround scope. We are one of the largest operations and maintenance service providers in the United States and are onsite at over 60 refineries and petrochemical plants.

Zachry Engineering has extensive refining experience, including performing engineering and design work for nearly 50 refineries globally. Our refining experience spans the complete project life cycle - from single process unit conceptual studies, large scale revamp and retrofit projects, turnaround engineering and design, to turnkey delivery of major capital expense projects. Zachry Group has the technical and project execution expertise to deliver on the most challenging refinery work.

Through our maintenance and turnaround businesses, we lower our customers’ total cost of ownership by working collaboratively on strategies to improve process and industrial safety performance, enhance ROI for project delivery and drive first quartile asset performance with reliability, maintenance and turnaround strategy/optimization, enhanced digitization, Advanced Work Packaging and other work management and operational excellence processes.
