Rigger Level 3 Aramco Notes (2024)

This content is structured as comprehensive study notes for an Aramco Rigger Level 3 (Rigger III) certification or examination. Rigger III is considered an advanced level, focusing on complex lifts, critical lift planning, and supervisory responsibilities. These notes align with Saudi Aramco Engineering Standards (SAES) , Saudi Aramco Inspection Procedures (SAIP) , and standard rigging physics.

Aramco Rigger Level 3 – Comprehensive Study Notes 1. Roles and Responsibilities (Aramco Hierarchy) Rigger Level III (Advanced/Supervisor):

Authority: Can direct Level I and II riggers. Planning: Responsible for planning "Standard" and "Non-Critical" lifts (and assisting Engineers with "Critical" lifts). Inspection: Authorized to perform and document periodic inspections of rigging gear. Calculations: Must be proficient in calculating load weights, center of gravity (CG), and sling tension. Safety: Authorized to issue Permits to Work (PTW) related to lifting and serve as the "Lift Supervisor" or "Person-in-Charge" (PIC).

Distinction from Level II:

Level II can perform routine lifts and signal crane operators but cannot plan complex lifts or supervise a crew formally. Level III is a requirement for supervising lifts involving Mobile Cranes > 80 tons or Tower Cranes .

2. Aramco Lift Classifications Understanding lift categories is vital for Aramco exams. The classification dictates the engineering paperwork required. A. Standard Lift

Definition: A lift that does not meet the criteria for Critical or Non-Critical. Criteria: rigger level 3 aramco notes

Load is ≤ 75% of the crane’s rated capacity. No complex rigging required. No potential to damage critical plant equipment if dropped.

Requirement: A Lift Plan is required. Rigger III can approve it.

B. Non-Critical Lift

Definition: A lift involving unusual complexity or risk but not deemed "Critical." Criteria:

Load is between 75% and 90% of rated capacity. Use of two or more cranes (tandem lift). Blind lifts (where the operator cannot see the load). Lifting over live operating plants.
