Lifting and Rigging Calculations – Lugs, Padeyes, Beams and Lift Plans
Before you lift a vessel, skid or structure, the lifting points and lifting tools must be checked. SLETEC calculates and designs lifting lugs, padeyes, trunnions, tailing lugs, spreader bars and lifting beams.
We also prepare rigging studies, sling and shackle selection, centre of gravity reports and transport or sea fastening calculations, to ASME BTH-1, ASME B30 and DNV standards.

Frequently Asked Questions
Can you calculate one lifting lug quickly?
Yes. Single lifting lug or padeye checks are one of our most common small jobs.
Do you prepare lift plans?
Yes. We prepare rigging studies and lift plans for critical lifts.
Do you design lifting beams for load testing?
Yes. We design lifting beams and spreader bars with calculations and drawings ready for fabrication and proof load testing.
