Vessels
Column and vessel services refer to the specialized mechanical activities involved in the inspection, maintenance, repair, modification, and installation of vertical process columns and pressure vessels used in refinery operations. These components are critical for separation, reaction, and storage processes, and require high standards of safety, precision, and compliance.
