. A Level 3 rigger is expected to independently perform basic rigging functions, including equipment inspection and the execution of non-critical lifts. Core Responsibilities & Scope
According to official Saudi Aramco study guides, the Rigger III certification test is divided into two main parts:
Aim for a horizontal sling angle of 45 to 60 degrees whenever possible to maintain a safe margin of tension. 4. Rigging Mathematics and Formulas
Lifting near , power lines, or high-risk areas. Exam and Training Structure rigger level 3 aramco notes
Level 3 riggers are responsible for and quarantine decisions . The notes contain detailed rejection criteria:
Any lift exceeding 40 tons automatically becomes a Critical Lift and requires a formal, written critical lift plan signed off by a Rigger Level 1.

is mandatory during mobile operations and must wear a reflector vest and carry red and green flags. Scaffolding Rules
The examiners will test your .
With arm extended downward, forefinger pointing down, move hand in small horizontal circle. With arm extended downward
The sling cradles the load with both eyes attached to the hook. Note: This 200% rating only applies if the sling legs are completely vertical (90 degrees to the load). 5. Saudi Aramco Safety Protocols & GI Requirements
You must account for corrosion allowance and internal packing (catalyst, etc.) as live loads.
The sling wraps around the load and chokes back onto itself. This reduces the sling's capacity to approximate 75% to 80% of its vertical rating because of the sharp bend created at the choke point.
