Major Maintenance and Integrity of Storage Tanks
We guarantee the service life and operational safety of your storage systems. We execute major crude oil tank recovery projects, integrating precision engineering, qualified welding, and advanced surface treatments to ensure the safe containment of your hydrocarbons.
1. Preparation and Initial Diagnostic Phase
-
Degassing and Mechanical Cleaning: Sludge removal and deep cleaning of walls and floor to create a safe working atmosphere.
-
Inspection under API 653 Standard: Technical evaluation using Non-Destructive Testing (NDT) to determine the condition of the shells, structural profiles, and foundation.
-
Verticality and Settlement Studies: Geometric verification to detect deformations in the tank body or failures in the concrete ring.
2. Structural and Mechanical Repairs
-
Replacement of Floor and Hull Plates: Replacement of corroded or damaged plates using certified welding.
-
Roof Repairs (Fixed or Floating): Maintenance of pontoons, tire sealing systems, and support structures.
-
Manway and Fitting Interventions: Replacement or reinforcement of manways, inlet/outlet connections, and drainage systems.
-
Maintenance of Protection Systems: Repair of ladders, railings, and grounding systems.
3. Civil Works and Containment
-
Adaptation of Safety Dikes: Redesign and reconstruction of containment walls to comply with environmental regulations.
-
Repair of Concrete Rings: Crack injection and leveling of the tank's support base.
4. Surface Treatment and Coatings
-
Surface Preparation (Sandblasting): Abrasive cleaning to white metal or commercial grade as required by technical specifications.
-
Application of Epoxy Coatings: High-performance paint systems resistant to chemical and environmental corrosion (internal liners and external paint).
5. Final Testing and Commissioning
-
Hydrostatic and Leak Testing: Verification of structural integrity through controlled filling.
-
Vacuum Testing: Inspection of bottom welds to guarantee zero leaks.
-
Certification of Fitness for Service: Delivery of a quality dossier and final post-repair inspection report.
