We rely on our core supervision and managers to deliver safe, efficient, cost effective projects at an accelerated rate, no matter what challenges may arise.

Low-Temp & Cryogenic Storage

TIW engineers, fabricates and erects API 620 tanks for low temp and cryogenic storage. Satisfying unique requirements for storage and containment, this standard allows for the design and construction of a broad range of tank shapes and sizes with operating pressures up to 15 PSI.

Misc. Fabrication & Field Erection

TIW custom fabricates and erects steel plate structures of all types, in a wide range of shapes and sizes. We generally provide fabrication of plate components requiring field erection, with the exception of some specific replacement vessels for turnaround maintenance events in oil refineries and pulp & paper mills.


TIW brings decades of experience and expertise in the fabrication and field construction of hydroelectric penstocks. Penstocks play a critical role in helping water get to a powerhouse – the heartbeat of a hydroelectric facility. Required to withstand high hydraulic pressure under both static and transient conditions, penstocks are designed, fabricated, and erected to precise specifications for maximum safety and lifespan. Steel is a material of choice for construction of penstocks due to its durability.

Pressure Vessels

TIW comonly designs, fabricates and field erects pressure vessels for turnaround maintenance events in oil refineries along with the Oil Sands, Pulp & Paper, Wastewater & Biological Treatment, and other industries.

Storage Spheres

TIW designs, engineers, fabricates and constructs high quality pressurized ambient and low-temperature spheres for liquid and gas storage in the Petrochemical/Refining, Chemical, and Wastewater & Biological Treatment industries.

Tank Maintenance & Repair Services

TIW is renowned for its expertise in repairing API tanks and ASME Pressure Vessels at petrochemical plants, refineries and tank farms. With more than a century of experience in the aboveground storage tank industry, we’ve performed tank repairs and modifications on API tanks for a wide range of customers.

Turnaround Projects & Maintenance Events
