Mechanical Service · Tower & Drum
Tower, drum,
and reactor execution.
Distillation towers, fractionators, reactors, coke drums, and accumulator drums — internals work, code repairs, head cuts, and tray replacements executed by crews who live inside this scope every turnaround.
Overview
Tower work is unforgiving on schedule. PSI prebuilds, sequences, and staffs tower scope so the critical path stays on the critical path — and every internal is signed off before the manway closes.
