Rigger Level 3 Aramco Notes ((exclusive))
For Saudi Aramco, a Rigger Level 3 (Rigger III) is a professional certified to handle basic rigging operations under the supervision of a Rigger Level 1 or 2 AlRashed Group
Critical Formulas from the Aramco Notes
The written exam for Aramco Rigger Level 3 is notoriously unforgiving. Candidates are not permitted to use mobile apps; they must memorize specific formulas. The notes emphasize the following constants: rigger level 3 aramco notes
- Shackles – Bend radius >5%? No. Wear >10% of diameter? Reject.
- Eye bolts – Shoulder type only. No wire-wrapped or homemade.
- Spreader bars & lifting beams – Annual NDT, visible weld cracks = immediate red tag.
- Synthetic slings – Broken stitching, UV degradation (color loss), or knots (absolute prohibition).
Couplers: The Safe Working Load (SWL) for a right-angle coupler is typically 9.4kn, while an adjustable/swivel coupler is approximately 5.3kn. For Saudi Aramco, a Rigger Level 3 (Rigger
Load Dynamics: Identifying the center of gravity—especially for asymmetrical loads—and positioning equipment for balanced weight distribution. Essential Technical Notes & Formulas Shackles – Bend radius >5%
Option 3: Formal Notice / Safety Bulletin (For a worksite or email signature)
Hitch Types: Understanding the capacity reductions when using a choker hitch vs. a vertical hitch.
- Rigging planning and execution: This includes load calculation, risk assessment, and planning for rigging operations.
- Load calculation and weight estimation: Rigging personnel must be able to accurately calculate load weights and determine the required rigging equipment.
- Rigging equipment inspection and maintenance: Regular inspection and maintenance of rigging equipment are critical to ensuring safe and reliable operation.
- Crane operation and safety: The notes cover crane operation, safety procedures, and load handling techniques.
- Load handling and control: This includes techniques for controlling loads during lifting, moving, and setting down.
- Emergency procedures: The notes cover emergency procedures, including loss of load, crane failure, and personnel injury.
Hand Signals and Radio Protocol
While hand signals are standard, the Aramco notes add a layer of linguistic nuance. Because crews are often multinational, the Level 3 Rigger must verify that the crane operator understands the signal language (English, Arabic, Urdu, or Tagalog) before the lift begins.
