HMT Tank, headquartered in The Woodlands, Texas, is the global leader in aboveground storage tank solutions — a position it has held since its founding in 1978 and reinforced through a strategy of product innovation, strategic acquisitions, and an expanding international service footprint. With approximately 1,200 employees and operations across the US, Europe, and the Middle East, HMT Tank serves refineries, marketing terminals, chemical plants, and pipeline operators that collectively hold billions of barrels of liquid hydrocarbon storage capacity.
HMT Tank: Company Overview
HMT LLC was founded in 1978 with a specific mandate: to deliver better technology to the aboveground storage tank market. The company’s founders identified emissions control and floating roof reliability as the two dominant pain points for tank operators and built a product portfolio designed to address both. That original focus on emissions reduction and operational efficiency remains the core of the business nearly five decades later.
The company is backed by Tailwind Capital, a New York-based private equity firm, and has raised $130 million in total funding. In October 2022, Veronique Trudeau joined as Chief Executive Officer, bringing experience from Johnson Controls and GE affiliate FieldCore. Revenue is estimated at $750 million annually, placing HMT among the largest specialist tank technology businesses in North America.
Products: Floating Roofs, Dome Systems, and Emissions Reduction
HMT Tank’s product portfolio centres on aboveground storage tank components designed to reduce vapour loss, improve operational efficiency, and extend maintenance intervals. The core range includes internal and external seal systems — including gas-tight primary seals — pontoon floating roofs, full contact floating roofs, skin and pontoon roof systems, and seamless composite roofs. Each product line is engineered to reduce hydrocarbon emissions at the tank boundary, an increasingly critical compliance requirement across US and European regulatory frameworks.
On the structural side, HMT manufactures aluminium geodesic dome roofs — free-spanning structures that eliminate internal support columns and reduce maintenance access requirements. The company also produces floating suction systems, drain systems, and emissions reduction devices covering every penetration point on a storage tank. For operators managing large terminal inventories, HMT’s full-contact floating roofs are specifically designed to minimise stranded inventory — liquid product trapped below the suction point that cannot be recovered without manual intervention.
The complete product suite is supported by an engineering team that provides tank capacity optimisation analysis, emissions modelling, and system design for both new-build and retrofit projects. The global tank terminal market increasingly demands this type of integrated product and engineering support, particularly as environmental compliance requirements tighten across the US, EU, and Gulf states.
Field Services: Tank Construction and Repair Across the US
Beyond its product manufacturing operations, HMT Tank runs a substantial Field Services division covering new tank construction and repair and maintenance of aboveground storage tanks throughout the Continental US and Caribbean. The division provides turnkey construction capability — engineering, foundations, fabrication, coatings, linings, and product installation — for both field-erected and shop-fabricated API 650 tanks. Specialty fabrication shops are located in the Midwest and Gulf Coast to support project delivery across both regions.
Repair and maintenance services include tank bottom repair and replacement, floating roof repair, fixed roof repair, and appurtenance servicing. For terminal operators managing ageing tank infrastructure under API 653 inspection cycles, HMT’s Field Services team provides a single-contractor solution across construction, inspection, and remediation. Companies such as Matrix Service Company and Tarsco (TF Warren Group) operate in adjacent segments of this market, but HMT’s combination of proprietary tank products and field service capability is a differentiator that pure-play construction contractors cannot replicate.
Inspection Services: The Weld Spec Acquisition
In March 2023, HMT Tank acquired Weld Spec, Inc., a Lumberton, Texas-based inspection services provider with capabilities spanning third-party inspection, non-destructive testing (NDT), mechanical and metallurgical laboratory testing, rope access, and drone-based inspection services. The acquisition extended HMT’s service offering into pipeline, refining, petrochemical, wind energy, and manufacturing sectors beyond its core oil and gas storage client base.
Operating as Weld Spec — An HMT Company, the division gives HMT a full-service inspection proposition to sit alongside its product and field service capabilities. The combination of tank technology products, construction services, and independent inspection represents a genuinely integrated offering — one that supports operators across the full asset lifecycle from new-build commissioning through to inspection-driven maintenance and eventual decommissioning.
HMT Tank in the Global Market
HMT Tank’s primary market is North America, where the Field Services division operates exclusively across the Continental US and Caribbean. Internationally, the company’s product lines — floating roofs, dome systems, seal systems, and emissions reduction devices — are deployed across Europe and the Middle East through its global engineering and project teams. Clients include marketing terminal operators, refinery owners, petrochemical plant operators, and pipeline companies managing bulk liquid storage assets.
The company’s engagement with major terminal operators is well documented. HMT’s team participated in LBC Global Safety Day events at LBC’s Seabrook, TX and Sunshine, LA facilities, reflecting an active client relationship with one of the sector’s leading independent terminal operators. As the North American tank and terminal EPC market continues to absorb new capital across LNG, renewable fuels, and chemical storage, HMT’s integrated product and service model positions it to capture both greenfield construction work and the growing wave of inspection-driven maintenance across the existing asset base.
