Tank Remedial Work Signoffs

Elevate your operations with our premium tank solutions. Storage tanks play a vital role in many industries, storing everything from fuel and chemicals to food and water. But with time and use, storage tanks can become damaged, posing a risk to safety and reliability. That’s where storage tank repair comes in. By having your storage tanks regularly inspected and repaired by a qualified contractor, you can help to ensure that they remain safe and reliable for years to come.

Addressing common causes of Storage Tank failure

We recognise the crucial role of storage tanks in various industries, handling hazardous materials and substances. We adhere to stringent EEMUA 159 and API 653 standards. These internationally recognised standards provide detailed guidance on ensuring the safe and reliable design, construction, inspection, and repair of storage tanks.

Our comprehensive remedial work services address a wide range of factors that contribute to storage tank failures, including:

Corrosion: Corrosion is a prevalent cause of tank wall weakening and increased susceptibility to failure. Our team employs advanced NDT methods to detect corrosion and implements appropriate repair techniques to restore the tank’s integrity.
Weld defects: Weld defects can arise during fabrication or as a result of operational damage, creating weak points in the tank walls. We utilise expert welding techniques and rigorous inspection procedures to eliminate weld defects and ensure structural integrity.
Dents and gouges: Dents and gouges in the tank walls compromise structural integrity and increase the risk of failure. Our team employs precise repair methods to eliminate dents and gouges, restoring the tank’s strength and serviceability.
Environmental damage: Storage tanks can be subjected to environmental hazards such as lightning strikes, earthquakes, and floods. We assess the extent of environmental damage and implement appropriate repair measures to safeguard the tank’s integrity.

Key benefits of our Tank Remedial Work Signoffs

Assurance that repairs are to code

The service ensures that repairs are completed in accordance with the applicable standard, such as EEMUA 159 or API 653. This helps to avoid poorly designed or completed repairs that could potentially cause further damage to the tank or lead to safety or environmental concerns.

Extended service life / best practice

Having repairs completed to code helps to extend the service life of the tank and ensure that it is operating in a safe and reliable manner.

Documentation and sign-off

The service provides clients with a documented record of the repair work and the results of the NDT inspection. This documentation is important for insurance purposes and for demonstrating compliance with regulatory requirements.

Step 1: Inspection
Step 2: Preparation
Step 3: Repair
Step 4: Testing
Step 5: Documentation

Thorough Visual Inspection: Our team conducts a comprehensive visual inspection of the tank’s exterior and interior to identify any visible damage, such as dents, gouges, cracks, or corrosion.
Advanced NDT techniques: We employ a range of advanced NDT methods to detect hidden defects or anomalies that may not be visible to the naked eye. These methods include:
- Ultrasonic Testing (UT): UT measures the thickness of the tank wall, providing insights into the extent of corrosion or damage.
- Magnetic Particle Testing (MPI): MPI detects surface discontinuities in the tank’s material, such as cracks or delaminations.
- Dye Penetrant Testing (DPI): DPI highlights cracks and defects by penetrating into the tank’s surface and revealing them under ultraviolet light.
- Radiographic Testing (RAD): RAD uses high-energy X-rays to create detailed images of the tank’s internal structure, revealing any hidden defects or voids.
Data analysis: The collected NDT data is meticulously analysed to assess the severity of the damage and determine the appropriate repair approach.
Root cause analysis: Our team conducts a root cause analysis to identify the underlying factors that contributed to the tank damage. This helps to prevent similar issues from reoccurring in the future.

Cleaning and decommissioning: The tank is thoroughly cleaned to remove any dirt, debris, or contaminants that could interfere with the repair process. If necessary, the tank may be temporarily decommissioned to ensure a safe and efficient repair environment.
Material removal: Damaged material, such as corroded sections, weld defects, or dents, is carefully removed from the tank using appropriate methods, such as grinding, cutting, or chipping.
Area preparation: The surrounding area is prepared to accommodate the repair process, including setting up workspaces, erecting barriers, and ensuring adequate access to the tank.

Repair plan implementation: The approved repair plan, developed based on the inspection findings and root cause analysis, is meticulously implemented.
Welding techniques: Precise welding techniques are employed to restore the tank’s integrity, ensuring structural soundness and leak-tightness.
Patching and material replacement: Appropriate patching materials, such as steel plates or composite materials, are selected and applied to the damaged areas to restore the tank’s structural integrity.
Compliance with industry standards: The repair process adheres to stringent industry standards, such as EEMUA 159 and API 653, ensuring the safety and reliability of the repaired tank.
Material certification: All materials used in the repair are certified to meet the required standards for safe and reliable operation.

Rigorous NDT verification: The repaired areas are subjected to comprehensive NDT testing, including ultrasonic testing, magnetic particle testing, dye penetrant testing, and radiographic testing, to verify the effectiveness of the repair and confirm the tank’s structural integrity.
Pressure testing: The tank undergoes pressure testing to ensure its ability to withstand the operating pressures and avoid sudden failures.
Hydrostatic testing: For water tanks, hydrostatic testing is conducted to ensure the tank can withstand the maximum operating pressure while maintaining its structural integrity.
Compliance with regulatory requirements: The test results are reviewed against relevant regulatory requirements to ensure compliance and demonstrate that the tank meets all applicable safety standards.

Comprehensive report preparation: A comprehensive report is prepared, documenting the entire repair process, including the inspection findings, repair methods, test results, and sign-offs.
Detailed NDT reports: Detailed NDT reports are generated for each NDT method, providing clear documentation of the test results and their interpretation.
Regulatory compliance documentation: All regulatory compliance documents are included in the report, demonstrating adherence to relevant safety standards.
Insurance purposes: The report serves as valuable evidence for insurance purposes, demonstrating the thoroughness and compliance of the repair work.
Maintenance records: The report is integrated into the tank’s maintenance records, providing a complete history of the tank’s condition and repairs.
