Protecting the Integrity of Critical Infrastructure
Critical infrastructure changes throughout its operating life. Corrosion develops, materials degrade, equipment ages, structures deteriorate, technologies become obsolete, operating conditions change, and facilities may eventually be required to perform beyond the conditions for which they were originally designed. Argan Int. Group of Companies provides integrated asset integrity, inspection, engineering assessment and rehabilitation services to help owners understand these conditions and determine the appropriate technical response.
Our approach connects field inspection and condition data with multidisciplinary engineering analysis. Rather than identifying deficiencies in isolation, we evaluate what they mean for continued service, safety, reliability, remaining life and future investment. Where intervention is required, findings can be developed into engineered repair, replacement, rehabilitation, modernization or life-extension programs and progressed through procurement, field execution, testing and recommissioning.
From Condition to Engineered Action
Inspection Is the Beginning — Not the Outcome
Inspection data has limited value unless it leads to sound engineering decisions. Argan Int. approaches asset integrity as a structured progression from condition identification to technical assessment and ultimately to corrective action.
The process begins by establishing the asset history, design basis, operating conditions, previous inspection information and known areas of concern. Inspection and diagnostic activities are then selected according to the equipment, materials, deterioration mechanisms and technical questions that need to be answered.
Findings are evaluated by the appropriate engineering disciplines to determine their significance. This may include remaining thickness, structural capacity, material condition, equipment degradation, integrity threats, remaining service capability or suitability for changed operating conditions.
The resulting engineering assessment provides the basis for deciding what happens next: continued operation, additional monitoring, detailed investigation, repair, replacement, rehabilitation, modernization or life extension. Where physical intervention is required, Argan Int. can develop the findings into an executable rehabilitation scope rather than leaving the client with an inspection report alone.
Our Integrity Capabilities
Seven Integrated Capabilities
Asset Condition Assessment
Before decisions can be made about rehabilitation, replacement or continued service, the actual condition of the asset must be understood.
Argan Int. develops structured condition-assessment programs around the equipment, structures and systems being evaluated. The assessment begins with available design documentation, operating history, previous inspection records, modifications, failure history and known deterioration mechanisms before progressing into field verification and technical evaluation.
Our multidisciplinary approach allows mechanical equipment, piping, structures, electrical systems, instrumentation and other critical infrastructure to be considered within the wider operating context rather than as unrelated components.
The objective is to establish a defensible technical baseline: what condition is the asset in today, where has deterioration occurred, which findings are significant, and which areas require deeper investigation? This baseline provides owners with a clearer understanding of asset condition and creates the technical foundation for subsequent integrity assessment, rehabilitation planning, capital prioritization and decisions concerning future service.
Key Capabilities
Asset history and documentation review
Baseline condition assessment
Field condition surveys
Degradation and damage identification
Remaining-condition evaluation
Critical-system assessment
Technical findings and recommendations
Condition-based rehabilitation priorities
Inspection & Non-Destructive Examination
Effective integrity assessment requires inspection methods selected for the specific asset, material, geometry and deterioration mechanism under investigation.
Argan Int. coordinates conventional and advanced inspection and non-destructive examination programs through qualified specialist resources appropriate to project requirements. Depending on the scope, techniques may include visual examination, ultrasonic testing and thickness measurement, radiographic examination, magnetic-particle testing, liquid-penetrant testing and other specialized inspection methods.
The purpose is not to perform testing simply because a method is available. Inspection plans should be designed around a defined engineering question — locating corrosion, characterizing defects, evaluating weld condition, identifying cracking, determining material loss or establishing information required for further engineering assessment.
Inspection results are documented and transferred into the integrity-engineering process, where detected conditions can be evaluated according to their significance and the requirements of continued service.

Integrity Engineering & Fitness-for-Service
Finding a defect does not by itself determine whether equipment must be replaced. Integrity engineering evaluates detected deterioration against the design, material properties, operating conditions, applicable criteria and expected future service of the asset.
Argan Int. coordinates engineering assessments to determine whether affected equipment or structures remain suitable for continued operation and what limitations, corrective measures or further investigations may be required.
Where applicable, fitness-for-service methodologies and recognized engineering standards provide a structured basis for evaluating whether equipment can remain in operation, requires repair, should operate under defined restrictions, or needs replacement.
The objective is to replace assumption with engineering evidence — allowing owners to make better-informed decisions concerning safety, continued operation, intervention requirements and capital expenditure.

Engineering recommendations
Corrosion & Materials Integrity
Corrosion and material degradation can progressively reduce the integrity of piping, vessels, tanks, structures and other infrastructure long before the effects become obvious through operating performance.
Argan Int. supports the assessment of corrosion mechanisms, material condition and degradation patterns to help determine the cause, extent and significance of deterioration, including review of materials of construction, process and environmental conditions, corrosion history, coatings, linings, cathodic protection, previous inspection data and the effectiveness of existing protection measures.
Where degradation is identified, engineering evaluation can determine whether the appropriate response is continued observation, improved protection, material replacement, localized repair, coating renewal, cathodic-protection improvement or broader system rehabilitation. Understanding the deterioration mechanism is particularly important — replacing damaged material without addressing the cause can simply recreate the same problem later.
Key Capabilities
Corrosion-mechanism assessment
Materials-condition evaluation
Corrosion-rate review
Coating and lining assessment
Cathodic-protection evaluation
Material-selection review
Degradation root-cause assessment
Corrosion-control recommendations
Structural & Civil Integrity
The integrity of process equipment and mechanical systems ultimately depends on the structures and foundations supporting them. Age, environmental exposure, settlement, corrosion, cracking, vibration, loading changes and previous modifications can affect concrete, steel structures, foundations, pipe supports, equipment supports and other civil infrastructure.
Argan Int. coordinates structural and civil assessments to identify deterioration, evaluate its significance and determine whether existing infrastructure remains capable of supporting current or proposed future service. The process may include visual surveys, review of original design information, dimensional verification, material-condition assessment, structural analysis and evaluation of changed loads or operating requirements.
Where deficiencies are identified, recommendations can be developed for structural strengthening, concrete rehabilitation, steel replacement, foundation remediation, support modification or other corrective measures. This capability is particularly important when existing facilities are being upgraded or repurposed, because new equipment and operating requirements can impose conditions that were not part of the original design.

Rehabilitation & Engineered Repair
The real value of integrity assessment is realized when findings are converted into effective corrective action. Where assessment identifies deterioration that requires intervention, Argan Int. can develop rehabilitation requirements into defined engineering scopes covering repair, replacement, strengthening, renewal or system modification.
The solution is selected according to the condition identified, technical risk, expected remaining service, operating requirements, constructability and lifecycle economics. A localized repair may be appropriate in one situation; complete replacement or broader rehabilitation may provide better long-term value in another.
Engineering development can include design calculations, drawings, specifications, material requirements, work packages, construction methodology and testing requirements. Through the wider capabilities of Argan Int. Group of Companies, approved rehabilitation scopes can then progress into procurement and field execution with technical continuity between the team that evaluated the problem and the teams implementing the solution.

Modernization & Life Extension
Some assets remain fundamentally sound but require modernization to continue operating effectively, meet changed requirements or remain economically competitive. Argan Int. supports owners in evaluating whether existing infrastructure can be upgraded or life-extended rather than replaced entirely.
The assessment considers current asset condition alongside future operating requirements, equipment obsolescence, maintainability, system limitations, technology availability and the investment required to achieve the desired service life. Modernization may involve replacement of obsolete equipment, electrical-system renewal, instrumentation and control upgrades, structural modifications, equipment improvements or wider brownfield integration.
Life-extension decisions require particular discipline. Extending operation should be based on evidence that critical equipment and systems remain suitable for the intended future service and that identified deficiencies can be appropriately addressed. By combining condition assessment with engineering and execution capability, Argan Int. helps clients establish a practical roadmap for extending productive asset life while directing capital toward the areas that provide the greatest technical and operational value.

Swipe through the 5 stages
Argan Int.'s approach is designed to maintain continuity from the first indication of deterioration through final technical resolution. Inspection findings are not treated as isolated data points; they become inputs to engineering decisions that determine the most appropriate path forward. Depending on the assessment, the answer may be continued service, further investigation, repair, rehabilitation, replacement, modernization or life extension.
Brownfield Execution
Engineering Change Within an Operating Facility
Rehabilitation of an existing facility is fundamentally different from construction on a greenfield site. Existing equipment, undocumented modifications, restricted access, operating systems, live interfaces, shutdown limitations and incomplete historical information can all influence how work must be engineered and executed.
Argan Int. approaches brownfield rehabilitation with particular attention to these interfaces. Existing conditions are verified before final design wherever practical. Tie-ins, isolation requirements, temporary arrangements, construction access, lifting requirements and work sequencing are considered as part of engineering development rather than left entirely to field resolution.
Where rehabilitation must be performed during a planned shutdown or controlled operating window, engineering, procurement and field activities can be developed around the required execution sequence — reducing uncertainty during implementation and providing a stronger connection between the condition discovered in the field, the engineered solution and the practical requirements for installing that solution within an existing facility.
How We Approach Asset Integrity
Engineering-Led. Evidence-Based. Action-Oriented.
Inspect for a Reason
Inspection activities are selected around defined integrity questions and credible deterioration mechanisms. The objective is to obtain the information engineering needs to make a decision — not simply to accumulate inspection data.
Evaluate the Significance
Not every indication carries the same technical consequence. Findings are assessed against material condition, design requirements, operating conditions and future service to determine their actual significance.
Prioritize the Intervention
Recommendations consider technical risk, operational impact, remaining service requirements, constructability and lifecycle economics, helping owners distinguish immediate requirements from work that can be planned strategically.
Engineer the Resolution
Where intervention is necessary, integrity findings can progress into engineered repair, rehabilitation, replacement or modernization scopes supported by procurement and field execution capabilities across the Group.
The Argan Int. Integrity Approach
From Inspection to Asset Renewal
Argan Int. Group of Companies connects inspection, multidisciplinary engineering and rehabilitation within one technical pathway. We do not view inspection as the end product. The purpose is to establish reliable information about asset condition, understand what that condition means for future service and provide owners with a technically sound basis for action.
That may mean confirming that an asset remains suitable for continued operation. It may mean identifying a targeted repair. Or it may reveal that rehabilitation, replacement, modernization or life extension represents the more appropriate long-term solution. When physical intervention is required, the Group's wider engineering, procurement and construction capabilities provide continuity from assessment to implementation.
