STRUCTURAL was contacted by a major refinery in Texas to perform work to their Delayed Coking Unit (DCU) and Sulfur Recovery Unit (SRU) structures during a scheduled shutdown. More than eight offices provided project management and field labor to complete the work.

The scope of work for the SRU included the repair and installation of a 4-inch thick durability liner to the walls of the 10-plus year old sulfur pit. The scope also included the casting and replacement of eight pre-cast roof panels, as well as exploratory beam, column and soffit repair.  STRUCTURAL’S StrongPoint Engineering supplied the engineered design.

Work on the DCU included the installation of new grout rings for the coke drum replacement project.  The team utilized a 4300 Te crane to remove and replace the derrick structure and the six coke drums.

Teamwork, pre-planning, project execution, and safety were essential features of these two major projects.
