Lorneville

What Lorneville does

Lorneville is an employee-owned industrial mechanical contractor founded in 1977 by Rosaire and Rejean Dumouchel in New Brunswick, Canada. The company delivers a unified portfolio of construction, maintenance, turnaround, pipe and pressure vessel fabrication, and specialty services (turbines, heat exchangers, electrostatic precipitators, rigging) to enterprise clients in four primary verticals: petrochemical, power generation, pulp and paper, and mining and minerals. Notable technical capabilities include proprietary phased-array ultrasonic weld inspection procedures that delivered 15% productivity gains on LNG tank construction, specialized fabrication and welding techniques for nuclear CANDU 6 refurbishment, and a TSSA-approved Alternative Piping Process Quality program. The company operates a 16,000 sq ft ISO 9001-certified fabrication facility in Saint John, NB and a 20,000+ sq ft fabrication facility in Edmonton, AB, supported by regional offices in Saint John, Burlington, and Edmonton.

The business model combines project-based construction and turnaround work (one-time scope contracts) with recurring managed services for facility maintenance, including Tank Life Extension programs and multi-year maintenance agreements. Pricing is negotiated per-project based on scope, complexity, and schedule, with no public rate cards. Revenue is generated through direct enterprise sales, where Project Core Teams (Senior Project Manager, senior trade supervisors, project engineers) provide on-site leadership from planning through execution. The company has logged nearly 1.7 million petrochemical field hours, 1.5 million maintenance hours, and over 1 million turnaround hours in the past five years, with peak workforce scaling to 2,700 workers on the 2015 Irving Oil turnaround.

Lorneville maintains a deep certification stack (ISO 9001:2015, CSA W47.1/W47.2, CSA N285 nuclear, ASME across all 10 provinces, Lloyd's Register, COR) that prequalifies it for high-risk industrial work, and has been named one of Canada's 50 Best Managed Companies (Platinum). Customer logos include Irving Oil, Canaport LNG, NB Power, AECL, Suncor, Imperial Oil, Irving Pulp & Paper, Vale INCO, PotashCorp/Nutrien, CNRL, and Resolute Forest Products. The company has begun repositioning toward energy transition and marine renewables, including an Offshore Wind Opportunities Guide and a December 2022 partnership with Saint John Industrial Parks.
