Description
Vessel Erection — Rotational Lift Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Analyses the rotational erection of tall vertical pressure vessels — the typical lift configuration where a main crane holds the upper trunnions/lugs and a tailing crane controls the bottom, rotating the vessel from shipped-horizontal to installed-vertical. Calculates crane loads at every rotation angle, plus vessel bending stress during the lift.
What’s Inside the Excel File
- Inputs — vessel weight, vessel length, CG location, top lug location, tailing lug location, dynamic factor, sling lengths
- Main crane load vs rotation angle (0° to 90°)
- Tailing crane load vs rotation angle
- Critical angles — maximum main crane load and tailing release point
- Vessel bending moment during lift — checks vessel itself doesn’t fail
- Lug load envelope for top and tailing lugs
- Crane selection support data
Who This Is For

Frequently Asked Questions
Two-crane only?
Standard rotational lift uses main + tailing crane. Single-crane vertical lift is a different methodology.
Replaces full lift study?
This sheet handles the engineering check. Final lift studies typically include site-specific obstructions, ground bearing, and method statements which the rigging contractor produces.
