Major Overhaul and Field Engineering Services for Drilling Rigs
Electromechanical systems integration, structural inspection, and re-certification of onshore and lake drilling rigs and barges.
1. Operational Challenge
Continuous cyclic drilling loads combined with marine/lacustrine atmospheric attack cause structural fatigue on masts, substructures, and hoisting blocks, requiring periodic recertification.
2. Engineering & Execution Solution
Mobile multidisciplinary field teams executing Category III and IV inspections per API RP 4G, structural member repairs, crown block alignment, and drawworks and mud pump overhauls.
3. Quality, Inspection & HSE Protocol
- Visual inspection and phased array ultrasonic / magnetic particle non-destructive testing.
- Structural member cut-and-replace using certified high-strength structural steel.
- Major maintenance on rotary tables, top drives, and driller control consoles.
- Static and dynamic proof load testing using calibrated load cells.
4. QA/QC Deliverables & Dossier
Operational fitness certificate for mast and substructure endorsed by a certified mechanical engineer, updated life book, and complete NDT inspection dossier.
