Description
Tailing Lug Design Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Designs the tailing lug welded near the base of a tall pressure vessel — used by the auxiliary crane during vessel rotation from horizontal to vertical erection orientation. The tailing lug is the second pick point that complements the main lifting lugs near the vessel top.
What’s Inside the Excel File
- Inputs — vessel weight, vessel length, lug location, sling angle to ground, lug plate dimensions, pin diameter, material grade, dynamic factor
- Tailing load calculation from rotation geometry
- Net section tension at pin hole
- Pin bearing on lug plate
- Shear-out at lug edge
- Weld capacity at lug-to-shell connection
- Shell local stress contribution check
Who This Is For
- Pressure vessel design engineers
- Vessel erection and rigging engineers
- EPC mechanical teams on tall column installation
- Vessel fabricators supplying erection lugs
Codes & Standards Referenced
- ASME BTH-1 — Below-the-Hook Lifting Devices
- ASME VIII Division 1 — vessel shell stress principles

Frequently Asked Questions
Rotational erection vs vertical lift?
Tailing lug specifically supports the rotational erection where one crane holds the top and a second (tailing) crane controls the bottom. For straight vertical lift see our Vessel Erection — Rotational Lift sheet.
Local shell stress (WRC 107)?
This sheet handles the lug itself. For local shell stress per WRC 107/297, dedicated FEA or WRC methodology is needed.
