## Working on now

- Integrated field-plus-shop delivery: combining heat-exchanger manufacturing, repair/modification, piping-spool fabrication, and field execution through one source.
- Turnaround, maintenance, emergency/unplanned-outage, and capital-project support, including rapid-response manufacturing and repairs and off-site staging.
- Shop capability remains centered on highly engineered heat-transfer equipment: shell-and-tube exchangers, vessels/reactors, towers/columns, coke-drum components, repairs, machining, testing, cleaning, and decontamination.
