Tank Terminal EPC Companies North America: 2026 Market Outlook
LNG export terminal construction remains the highest-value segment for tank terminal EPC companies in North America, with several Gulf Coast projects in active development or pre-FEED phases. Alongside LNG, hydrogen storage, carbon capture containment, and renewable diesel terminal conversions are driving a new wave of specialist fabrication demand that favours contractors with both conventional API 650 capability and cryogenic design experience.
Digital construction management, modular fabrication, and advanced coating systems are increasingly standard across this group — reducing field installation time and improving QA outcomes on projects where schedule overrun carries significant financial penalties.

Who is the largest tank terminal EPC company in North America?
CB&I, operating within McDermott International, is widely regarded as the largest and most technically advanced tank terminal EPC contractor in North America. The company has built more full-containment LNG tanks than any other contractor globally and has over a century of storage tank engineering experience across the Gulf Coast and international markets.
What does EPC stand for in tank and terminal construction?
EPC stands for Engineering, Procurement, and Construction. In tank and terminal projects, an EPC contractor takes responsibility for the full project delivery — from front-end engineering design through equipment procurement and field construction to commissioning. This single-contract model reduces client risk and consolidates project management accountability.
What standards do North American tank terminal EPC companies build to?
The primary standards governing storage tank construction in North America are API 650 (welded aboveground storage tanks for oil), API 620 (large low-pressure and cryogenic tanks), and AWWA D100 (water storage tanks). LNG containment also requires compliance with NFPA 59A and EN 14620. Major EPC contractors hold certifications under ASME, AWS, and OSHA across their fabrication and field operations.
Which North American EPC companies are involved in LNG terminal construction?
CB&I (McDermott), Bechtel, Kiewit, and McDermott International are the primary North American EPC contractors with demonstrated LNG terminal delivery capability at scale. Tarsco and Matrix Service Company have also completed LNG storage facility projects, particularly for smaller-scale and peak-shaving LNG applications.
How has the TRC Companies acquisition affected its position in this ranking?
TRC Companies was acquired by WSP Global in February 2026. Its core engineering and environmental consulting capabilities — including hydrogen project development and CCS infrastructure — continue under WSP ownership. TRC retains its place in this ranking on the basis of those continuing capabilities, now with the additional resource base of one of the world’s largest professional services firms behind it.
