Project Description


Greenberry was contracted by Bechtel National Inc (BNI) to fabricate six large diameter alloy and stainless-steel corrosion-resistant process vessels for Hanford’s Waste Treatment and Immobilization Plant (WTP), also know at the Vit Plant. The vessels will help process liquids throughout the effluent management facility.

Design, fabrication, testing, and inspection of the ASME, Section VIII, Division 1 vessels were done at our Vancouver, Washington, and Corvallis, Oregon, facilities. The vessels were hydrotested, as well as inspected with RT, PT, and UT methods for quality control. Ranging in function and size, the over-dimensional vessels were transported by specialized transport trailers over-the-road to Richland, WA, with the largest vessel was moving at night to minimize traffic and safety impacts.
