From Our Partners

“Our 2021 turnaround was one of the largest midstream TARs in 2021. Sierra used 2D/3D waterjetting technology to clean some of our most difficult and largest vessels in our plant. From Sierra’s clean-in-place chemical circulations to their waterjetting technology, we were pleased with results from their cleaning techniques. Sierra not only finished within schedule but under budget.”
