Routine mechanical planning covers day to day and PM work. Internal inspections of columns, reactors, and exchangers are usually turnaround scope, listed here so the full equipment picture is in one place. Ownership varies by site. Vessels, tanks, and piping often sit with the fixed equipment or inspection group; pressure relief valves may sit with a dedicated valve shop. Tag prefixes vary by site; check the site equipment numbering standard. Intervals must follow manufacturer guidance, API and code requirements, inspection plans, and site procedures.

Ownership of some devices varies by site. Relief valves, motor operated valves, thermowells, and analyzers may sit with fixed equipment, electrical, inspection, or analyzer groups rather than the instrument shop. Tag letters are a guide, not a site rule. PM tasks and intervals must follow manufacturer guidance, regulatory requirements, safety integrity requirements, and site procedures. Safety instrumented function components (sensors, logic solvers, and final elements) carry proof test requirements in addition to routine PM.
