USI Industrial Services

What USI Industrial Services does

USI Industrial Services is a privately held specialty mechanical contractor that delivers turnkey construction, maintenance, and turnaround services to major U.S. oil refineries. The company is headquartered in Marksville, Louisiana and operates as a wholly-owned subsidiary of Everus Construction Group, which is in turn controlled by MDU Resources Group, Inc. (NYSE: MDU). USI's core work centers on the most schedule-critical and craft-intensive refinery activities: turnkey plant turnarounds, FCCU and coker unit outages, heat exchanger extraction and replacement, process column revamps, specialty piping, Delta Valve installation, and specialty welding. It supports these activities with over 350 certified weld procedures covering exotic alloys (Chromes, stainless steel, Titanium, Inconel) and holds NBIC R-Stamp and ASME S, U, and PP certifications, which together authorize it to perform coded repair, alteration, and fabrication work on boilers, pressure vessels, and power piping — a qualification set that materially narrows the field of competing contractors.

The company's technical platform combines certified labor, owned specialty equipment, and disciplined pre-project planning. It maintains truck-mounted and aerial heat exchanger extraction equipment, bundle trailers, certified heavy rigging components capable of single-piece lifts up to 500 tons at 430-foot radius, and a computerized on-board tool inventory system that tracks job-site tooling to reduce loss. Project execution is anchored by Primavera P6-based planning, with work-package development and man-hour estimation beginning up to 18 months ahead of a planned outage, and crews are integrated with client engineering, operations, and maintenance teams under a "Total Partnered Management Team" model. The signature reference project — the Phillips 66 Coker Drum replacement at Ponca City, completed in September 2013 within a 33-day outage window — illustrates the scale at which USI operates: two 230-ton Coke Drums transported from Japan, a 231-ton Super Structure, and a 500-ton Penthouse/Derrick structure.

Commercially, USI operates a project-based, professional-services revenue model. Pricing is negotiated per project scope and is not publicly disclosed; quotes are typically obtained prior to commencement. The go-to-market motion is enterprise field sales, with direct engagement of refinery operations and maintenance leadership and on-site delivery of services across multiple U.S. sites. The customer base is concentrated in a single vertical — major oil refineries — and is led by an enterprise sales team structured around President Michael C. Murphy Sr., President of Business Development Marvin Turner, and Safety Director Nathan Terrell. Marketing channels are minimal, relying on safety record, project references, and direct relationships rather than digital campaigns, consistent with a reputation-driven B2B industrial services business.

Direct peers

• Matrix Service Company: Matrix Service Company builds and maintains storage tanks, terminals, and refinery/petrochemical process infrastructure, executing turnkey mechanical and turnaround scopes. Direct competitor in refinery mechanical construction and turnaround execution.
• Turner Industries Group: Turner Industries is one of the largest US specialty industrial contractors providing mechanical, piping, welding, scaffold, and turnaround services to refineries, petrochemical plants, and gas processing facilities. Directly comparable to USI in scope (piping, welding, vessel, turnaround) and customer base (major US refiners), though operating at significantly larger scale.
• Performance Mechanical, Inc. Performance Mechanical is a refinery-focused mechanical contractor specializing in piping, welding, and turnaround work for major US refiners. Smaller-scale direct peer to USI with overlapping craft-heavy refinery mechanical service offering.
• Austin Industrial: Austin Industrial provides mechanical, piping, structural, and turnaround services to refineries, petrochemical, and power clients nationally. Operates a multi-division craft services model that overlaps directly with USI's combined mechanical/welding/rigging offering to refining customers.
• Saulsbury Industries: Saulsbury is an EPC and specialty contractor delivering turnkey mechanical, tank, piping, and turnaround services to US refineries and midstream operators. Closely aligned with USI's capital-project-and-turnaround model and refining customer segment, with broader EPC reach.
• Brand Industrial Services: Brand Industrial Services delivers on-site industrial services including mechanical construction, welding, rigging, and turnkey turnaround execution to refineries and petrochemical operators across the US. Direct peer to USI in delivering multi-discipline refinery outage and capital project work under similar craft-intensive models.

Emerging players

• Mistras Group, Inc. Mistras Group provides inspection, mechanical integrity, and specialty services to refineries and petrochemical operators. Adjacent rather than identical to USI's mechanical construction focus, but serves the same refining customers with complementary outage-phase services.

Broad incumbents

• Day & Zimmermann: Day & Zimmermann's Industrial Services division delivers maintenance, modification, and construction services to refining, chemical, and power customers nationally. Broader portfolio than USI but operates a directly overlapping refinery mechanical/maintenance practice.
• Fluor Corporation: Fluor is a global EPC incumbent executing large-scale refinery and petrochemical capital projects, often self-performing mechanical and turnaround scopes that compete with USI for major outage and capital work packages.
• Worley Limited: Worley is a global energy, chemicals, and resources project delivery and advisory firm that competes for refinery capital project and turnaround work where it integrates with USI's market. Overlapping customer set and capability scope, scaled globally.
