The Saudi Aramco Rigger Level 3 (Rigger III) certification is a foundational credential required for personnel performing basic rigging and lifting tasks within Aramco facilities. A Rigger III typically handles standard loads up to 10 tons under direct supervision, focusing on equipment inspection, safe hitching, and clear communication with crane operators. Core Responsibilities of a Rigger III
Safe Handling: Move heavy equipment using specialized tools like cranes, hoists, and wire ropes.
Load Management: Accurately assess load weights and identify the Center of Gravity (CG) to ensure balance during a lift.
Equipment Inspection: Perform pre-use inspections on all rigging hardware, including slings, shackles, and hooks, and remove any defective gear from service.
Communication: Use standardized hand signals to direct crane operators and conduct pre-lift toolbox talks to inform the team of risks. Essential Technical Knowledge
The Aramco Rigger Level 3 exam focuses heavily on the following technical standards: Safety Factors: General Lifting: 5:1 safety factor for wire rope. Personnel Lifting (Man-Basket): 10:1 safety factor. Sling Angles:
Tension increases as the sling angle from vertical decreases.
Maintain a minimum sling angle of 60° whenever possible; never go below 30° without engineering approval. Hitch Types:
Basket Hitch: Distributes load across two parts of the sling, providing maximum capacity and stability. rigger level 3 aramco notes
Choker Hitch: Wraps around the load, which significantly reduces the sling's rated capacity. Hardware Color Coding: Green: Valid for use. Yellow: Approaching expiration. Red: Expired; do not use. Aramco Critical Lift Definition
A lift is classified as "Critical" if it meets any of the following criteria, requiring advanced planning and higher-level rigger oversight: Loads exceeding 90% of the crane's capacity. Lifting personnel. Tandem lifts (using two or more cranes).
Lifting near live equipment, power lines, or high-risk areas. Exam and Training Structure
The certification process generally involves both written and practical components:
Written Test: Approximately 50 multiple-choice questions to be completed in 2 hours. The passing score is typically 75%.
Practical Performance: A 3-day individual assessment where candidates demonstrate equipment setup and execution of various lifts.
Standard PPE: Mandatory site requirements include a safety helmet, safety shoes, safety glasses, and a full-body harness for work at heights. Certification Scheme Rigger Level 3 - EUROLINK SAFETY
Saudi Aramco Rigger Level 3 certification focuses on the safe execution of basic rigging tasks, including load weight estimation, equipment inspection, and standard hand signaling. This level typically authorizes riggers to handle loads up to 10 tons under direct supervision. Core Certification Topics The Saudi Aramco Rigger Level 3 (Rigger III)
Preparation for the Aramco Rigger III exam requires a deep understanding of the following areas: Load Calculations & Weight Estimation:
Formula: Weight = Volume × Density. For example, steel has a density of approximately Metric Conversion: Rigging Equipment Inspection:
Wire Rope Slings: Check for "bird-caging," kinks, and cut wires.
Synthetic Web Slings: Check for broken stitches, melting/charring, or cuts.
Hardware: Inspect shackles for worn pins or damaged threads and turnbuckles for distorted frames.
Color Coding: Verify that tools have current Aramco-approved color coding indicating they have passed recent inspection. Safe Lifting Practices: Critical Lift Plans: Required for lifts exceeding
of the crane’s capacity, tandem lifts (two cranes), or lifts over sensitive equipment.
Safety Factors: The standard Factor of Safety (FOS) for most rigging hardware is 5:1. Mastering Rigging Operations: A Technical Guide for Saudi
Outriggers: Must always be fully extended and supported by pads or mats. Signal & Communication:
Only one designated rigger should give signals to the crane operator at a time, unless an emergency "Stop" signal is needed (which anyone can give). Sling Capacity Quick Reference (Nylon Web Slings)

Introduction In the oil and gas construction and maintenance landscape of Saudi Aramco, rigging is not merely a mechanical task—it is a critical safety discipline. A Rigger Level 3 (often referred to as a Master Rigger or Senior Rigger in Aramco’s grading system) is expected to perform complex lifts, direct crane operators via hand signals, and inspect lifting gear without supervision. This article outlines the core competencies, load chart calculations, and permit requirements mandated by SAEP-358 (Lifting Equipment and Rigging) and the Saudi Aramco Safety Handbook.
According to Saudi Aramco’s Safety Management System (SMS) and GI (General Instruction) 7.1, a Rigger Level 3 is authorized to handle complex, multi-crane lifts, critical picks, and load calculations that exceed standard chart values. While a Level 2 knows how to tie a knot, a Level 3 knows why the knot fails under specific angles.
The official Aramco training notes categorize the Level 3 curriculum into four distinct pillars:
Unlike Level 1 (basic) or Level 2 (intermediate), the Level 3 Rigger must demonstrate:
In Aramco, a lift becomes "Critical" (requiring an Engineered Lift Plan) if it meets any of the following criteria:
