Memorizing standardized hand signals and radio communication protocols.
Snags, punctures, tears, or cuts exposing the internal red warning yarns. Broken or worn stitching in the load-bearing splices. Distortion or damage to fittings.
In the high-stakes environment of Saudi Aramco’s oil and gas facilities, precision is not just a metric—it is a currency. Among the various safety-critical roles, the stands out as the apex of lifting operations. Unlike Level 1 (basic signaling) or Level 2 (intermediate load handling), the Level 3 Rigger is expected to possess the tactical foresight of an engineer and the practical execution of a master technician. For candidates preparing for the Aramco Rigger Level 3 assessment, the "Aramco Notes" are not merely study guides; they are the operational bible.

T=Total Weight of LoadNumber of Slings×SAFcap T equals the fraction with numerator Total Weight of Load and denominator Number of Slings end-fraction cross SAF Example Problem: 4,000 kg Number of Sling Legs: 2 Sling Length (L): 3 meters Vertical Height (H): 2 meters Calculate SAF: Calculate Tension:
| Criteria | Threshold | | --- | --- | | Lift weight | ≥ 75% of crane capacity | | Load out of view | Blind lift | | Personnel lifting | Man basket operation | | Proximity hazard | Within 6 meters of live process lines or energized substations | | Tandem lifts | Any use of two cranes |
If a manufactured capacity tag is missing (though prohibited in actual field use), the rule of thumb formula for Wire Rope SWL in tons is:
Forearm vertical, forefinger pointing up, move hand in a small horizontal circle. Distortion or damage to fittings
The crane hook must be placed directly over the Center of Gravity.
The Rigger Level 3 Aramco notes cover a range of topics, including:
Tears, cuts, snags, or punctures that expose the internal red warning yarns.
No personnel are allowed under a suspended load. 4. Key Differences: Rigger III vs. Rigger II Rigger Level 2 Rigger Level 3 Lift Complexity Simple/Standard Complex/Critical Load Weight Typically 40 tons (and critical) Calculation Advanced (Multi-crane, COG) Authority General Rigging Specialized/Supervisory Rigger 5. Tips for Passing the Aramco Rigger 3 Exam create detailed lift plans
Miscommunication is a leading cause of crane accidents. For the practical exam, you will be tested on standardized crane hand signals:
At the end of the course, candidates are prepared to lead rigging teams, create detailed lift plans, and ensure safe working conditions throughout operations.
Identifying failures in various rigging components.
