Top 10 tank construction companies North America collectively service a market estimated to exceed $8 billion annually, driven by a replacement cycle for ageing aboveground storage tanks (ASTs), LNG infrastructure buildout across the US Gulf Coast, and continued petrochemical terminal expansion. From field-erected API 650 tanks to cryogenic LNG storage and specialised floating roof systems, these companies form the operational backbone of North America’s oil, gas, and liquid storage infrastructure.
How We Ranked the Top 10 Tank Construction Companies in North America
AST construction standards in North America are governed by API Standard 650, which sets the design and fabrication requirements for field-erected welded steel storage tanks across the oil, gas, and petrochemical sectors.
Rankings are based primarily on revenue and backlog size where disclosed in public filings or company reports. For privately held companies where financial data is not available, ranking criteria include project scale, geographic reach, specialism in oil and gas and petrochemical storage, and market reputation. All entries are active in the construction of aboveground storage tanks to API 650, API 620, or equivalent standards.

Top 10 Tank Construction Companies North America: What to Watch in 2026
Three forces are shaping the near-term project pipeline for the top 10 tank construction companies in North America. The US LNG export buildout — with multiple Gulf Coast terminals in active construction or pre-FID — represents the most significant single source of new cryogenic and LNG storage demand. Simultaneously, the AST replacement cycle is accelerating: a large proportion of the existing petroleum storage tank fleet was built in the 1960s and 1970s and is approaching or exceeding API 653 inspection-driven replacement thresholds. Petrochemical terminal expansion, particularly for ethylene derivatives and ammonia, adds a third demand vector. For the companies on this list, capacity constraints and competition for experienced field labour — rather than project demand — are the primary limiting factors. For a broader view of how storage infrastructure is evolving, see the Tank Terminals: The Complete Global Guide 2026.

Matrix Service Company ($1.1bn backlog) and Kiewit Corporation ($17bn total revenue) provide verifiable financial benchmarks. For privately held companies — including Fisher Tank, Tarsco, and Tanco Engineering — ranking is based on project scale, geographic reach, market specialism, and industry standing.
Which tank construction companies specialise in API 650 field-erected tanks?
CB&I, Tarsco (TF Warren Group), Fisher Tank Company, HMT Tank, and Tanco Engineering all hold strong API 650 field-erected tank credentials. CB&I and Tarsco are among the most active field-erected tank contractors in North America across oil, gas, and petrochemical sectors.
What is the difference between a tank EPC contractor and a tank construction specialist?
A tank EPC (engineering, procurement, and construction) contractor manages the full project lifecycle — engineering design, material procurement, and on-site construction — typically on large or complex terminal projects. A tank construction specialist focuses primarily on field fabrication and erection, often working as a subcontractor or under a client-supplied design. CB&I and Matrix Service Company operate as full EPC contractors; Tarsco and Tanco Engineering operate primarily as construction specialists.
Which North American tank construction companies also offer AST inspection and repair services?
HMT Tank, Matrix Service Company, Tarsco, and Tanco Engineering all offer inspection, maintenance, and repair services alongside new tank construction. HMT Tank added non-destructive testing and drone inspection capability through its 2023 acquisition of Weld Spec Inspection Services.
