Shackle Inspection & Certification in Ras Tanura
A shackle is a U-shaped forged steel connector closed with a pin, used to join slings, hoist rings, hooks and rigging in lifting, towing and anchoring. Dee and bow patterns, with screw pins or bolt, nut and split pin, are found across Saudi construction, offshore support, marine and oil and gas sites. Shackles are small and often reused without records, so an independent examination that checks the marking, the pin and the body geometry catches worn, bent or mismatched shackles before they reach a critical lift. Site of one of the world's largest oil refineries and export terminals, with continuous maintenance and turnaround activity.
Shackle inspection in Ras Tanura: local context
Wire rope slings, webbing slings, shackles and hooks left out in yards or coastal laydown areas around Ras Tanura face strong sun and salty air, which degrade synthetic slings and corrode steel fittings. When several crews draw from the same sling store, it is easy for an item's inspection history to be lost. EES carries out thorough examination of slings and rigging gear, removes defective items from service and tags compliant gear, so crews work with sets that are current and traceable.
Shackle inspection scope in Ras Tanura
- ✓Body for wear at the crown and the bow where the sling bears, and for ovality or spreading of the legs
- ✓Pin straightness, thread condition, shank wear and fit, confirming it is the original pin made for that shackle
- ✓Nut, split pin or locking arrangement on bolt-type shackles
- ✓Cracks, nicks, gouges and weld repairs, with magnetic particle inspection when there is doubt
- ✓Distortion of the eye holes and opening of the legs
- ✓Markings showing WLL, size, manufacturer, grade and traceability code
- ✓Screw pin fully engaged and the collar seated against the shackle ear
- ✓Corrosion pitting and loss of galvanising, particularly in coastal and marine service
Defects commonly found
- ✓Crown or pin worn so that the cross-section is reduced
- ✓Bent or stretched pin, or a pin replaced with a non-matching bolt
- ✓Legs spread or body twisted from side loading or overload
- ✓Stripped pin threads, or a missing nut or split pin on bolt-type shackles
- ✓Missing or illegible WLL marking
Standards
- ✓ASME B30.26 (Rigging Hardware)
- ✓EN 13889 (Forged steel shackles for general lifting purposes)
- ✓Manufacturer specifications and load charts
Testing
Where required for new, repaired or certified lots, a proof load test is typically applied at around twice the working load limit depending on the standard and client, with magnetic particle inspection added where cracking is suspected.
Frequency
Typically examined at least annually, with a pre-use visual check by the rigger, and more frequent re-inspection where client or site rules require it.

FAQs
Can you inspect a shackle on site in Ras Tanura?＋
Yes. Our inspectors travel to your yard or project site in Ras Tanura, including Ras Tanura Refinery and Ras Tanura Terminal, so the equipment does not need to be moved.
Which industries in Ras Tanura request shackle inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Ports, Logistics & Warehousing.
Can I replace a lost shackle pin with a bolt from the store?＋
No. The pin is a rated part of the shackle, and an ordinary bolt may not match its strength, diameter or fit. Use only the original or manufacturer-supplied pin, or replace the whole shackle.
What does the WLL on a shackle mean?＋
WLL is the working load limit, the maximum load the shackle is designed to carry in normal service when loaded in line, with a safety margin built in. The usable capacity falls if the shackle is side loaded or the sling angle is wide, so check the manufacturer's guidance.
