Diesel Desulfurization Unit (DDU)

This project involved construction of a new grass-roots modular Diesel Desulfurization Unit (DDU) for Tesoro's Kenai Alaska refinery. Haskell fabricated the sea-lift modules in Bellingham, WA, and then performed all on-site work in Alaska including foundations, structural steel, equipment setting, module setting, interconnecting piping, startup, and commissioning. The work included setting large distillation columns and also assembling fired heaters onsite. Haskell coordinated with other specialty subcontractors including electrical, insulation, painting, PWHT, and NDE.
