Pro tip: The latest update (2024 edition) includes new sections on synthetic rope slings (Dyneema) and load monitoring with pin load cells.
Unlike Level 2, where you estimate simple shapes, Level 3 requires calculating CoG for complex asymmetric loads—heat exchangers with attachments, distillation columns with nozzles, or modular pipe racks. rigger level 3 aramco notes
Key formulas in the notes:
Aramco-specific note: You must account for corrosion allowance and internal packing (catalyst, etc.) as live loads. Beware of counterfeit or outdated notes circulating on
Based on aggregated data from Aramco's training centers in Dammam and Jubail, most Level 3 candidates fail on three specific scenarios:
Question: You are rigging a heat exchanger weighing 22,000 kg. You have two 8-foot wire rope slings (WLL: 15,000 kg each at vertical). The lift points are 3 meters apart. The hook height is 2.5 meters above the lift points. Is this safe? Contractor-sponsored classes (e
