category III

Thorough Structural Integrity Assessment

We perform comprehensive visual inspections of all load-bearing components to ensure the structural integrity, safety, and reliability of your mast, derrick, or substructure systems.

Overview

Category III Inspection Overview

Category III inspections involve a detailed visual examination of all critical load-bearing components and structural members. The objective is to assess the overall condition, detect potential defects, and ensure compliance with safety and operational standards.

All findings are carefully documented using standardized checklists (Annex A–D), ensuring consistency and traceability across inspections.

Services Group

What’s Included in Category III Inspection

Structural Load Analysis

Detailed inspection of all load-bearing components to evaluate strength, stability, and overall structural integrity of the mast or derrick.

Rig-Up / Rig-Down Observation

Monitoring of rig assembly and disassembly operations to identify any operational risks, alignment issues, or safety concerns in real-time.

Mast & Derrick Inspection

Thorough visual assessment of mast and derrick structures to detect cracks, deformation, corrosion, or fatigue damage.

Substructure Evaluation

Inspection of the substructure to ensure proper support, alignment, and load distribution under operational conditions.

Safety Compliance Check

Verification that all components meet industry safety standards and regulatory requirements for safe operation.

Documentation & Reporting

All findings are recorded using standardized checklists (Annex A–D) and maintained in the permanent rig file for future reference.

Equipment Condition Assessment

Evaluation of overall equipment condition to determine maintenance needs and prevent unexpected failures.

Preventive Risk Identification

Early detection of potential issues to minimize downtime, improve safety, and extend equipment lifespan.
