Manufacturing Inspection & Vendor Surveillance Services

Independent Factory Inspection for Piping, Valves, Pressure Vessels, Towers, Structures & Rotating Equipment

Manufacturing risk is project risk.

We provide independent third-party manufacturing inspection and vendor surveillance services for oil & gas, energy, petrochemical, and heavy industrial projects worldwide.

With over 20+ years of fabrication and QA/QC experience, we support EPCs, PMCs, and Owner teams by ensuring equipment and materials are:

Fully compliant with ASME, API, ISO and project specifications
Manufactured in accordance with approved Inspection & Test Plans (ITPs)
Technically verified prior to shipment
Traceable and documentation-complete
Ready for safe installation and commissioning

We protect your project before equipment leaves the factory.

Comprehensive Manufacturing Inspection Scope

Factory Audits & Vendor Capability Assessment

Independent verification of manufacturer competence:

Manufacturing facility audits for ASME, API, ISO compliance
Vendor certification and capability evaluation
Quality Management System (QMS) assessment
Inspection readiness and fabrication resource review
Structured audit reporting with findings and corrective actions

Pre-award and ongoing vendor audits reduce procurement and execution risk.

Vendor Proposal Review & Technical Evaluation

Avoid technical deviations before Purchase Order award.

Technical proposal and data sheet review
Identification of compliance gaps and deviations
Clarification reports and risk assessment
Technical recommendation prior to PO placement

We identify specification risk early — not during fabrication.

Pre-Inspection Planning & ITP Alignment

Structured manufacturing control from project start:

Pre-Inspection Meetings (PIM) and Kick-Off Meetings (KOM)
Review of approved drawings, procedures, and specifications
ITP verification and stage confirmation
Hold / Witness point clarification
Communication and reporting protocol alignment

Clear inspection planning prevents inspection disputes.

Manufacturer Quality System & Capability Evaluation

Comprehensive evaluation beyond surface-level inspection:

Assessment of manufacturer’s Quality Management System (QMS) and QC procedures
Verification of compliance with contractual, code, and certification requirements
Evaluation of manufacturing capability, manpower, equipment, and inspection readiness
Review of resource allocation and production planning controls

We assess systemic manufacturing risk — not just product compliance.

Welding & Fabrication Qualification Verification

Technical validation of welding and fabrication controls:

Welding Qualification Test (WQT) review
Welding Procedure Specification (WPS) and PQR verification
Welder qualification and continuity record review
Fabrication and testing procedure compliance verification

Ensuring code compliance before production welding begins.

In-Process Manufacturing Inspection

Active quality control during fabrication:

Fit-up, welding, and final weld inspection
Positive Material Identification (PMI) & ferrite verification
NDT coordination and witnessing (RT, UT, PT, MT)
Post Weld Heat Treatment (PWHT) monitoring
Hardness testing verification
Production test witnessing

We monitor quality at critical manufacturing stages — not only at final inspection.

Dimensional & Visual Inspection

Precision verification against approved drawings:

Dimensional tolerance verification
Equipment alignment and geometry checks
Visual inspection of fabrication workmanship
Quantity verification against PO and packing list

Preventing costly site rework due to dimensional errors.

Testing, FAT & Performance Verification

Factory-level operational assurance:

Factory Acceptance Test (FAT) witnessing
Hydrostatic, pneumatic, and functional testing
Performance testing of static and rotating equipment
Mechanical completion verification
Test record validation

Ensuring performance compliance before shipment.

Surface Preparation & Coating Inspection

Coating failures lead to long-term asset risk.

Surface preparation verification per SSPC / NACE
Environmental condition monitoring
Dry Film Thickness (DFT) measurement
Coating defect inspection
Coating record review

Protecting corrosion control and asset life.

Certification, Identification & Traceability Control

Review of Material Test Certificates (MTCs)
Verification of code stamping and nameplates
Equipment tagging and traceability confirmation
Certificate of compliance review

Full traceability ensures code conformity and future inspection readiness.

Packing, Preservation & Shipping Inspection

Quality does not end at fabrication completion.

Packing and preservation verification
Export and transportation compliance checks
Marking and labeling inspection
Release recommendation prior to shipment

Ensuring equipment arrives at site damage-free and compliant.

Manufacturing Data Report (MDR) & Documentation Review

Prevent documentation rejection at shipment stage.

MDR review and validation
Cross-check against contractual requirements
Quality dossier completeness verification
Final documentation approval support

Shipment should never be delayed due to documentation gaps.

Inspection Reporting & Client Communication

Transparent and structured reporting at every stage:

Preparation of detailed inspection reports for each inspection visit
Timely submission of findings, observations, and recommendations
Immediate notification of critical deviations or nonconformances
Close coordination with client, manufacturer, EPC, and PMC stakeholders
Clear photographic and documentary evidence for traceability

Our reporting ensures informed decision-making and full project visibility.

NCR & Corrective Action Management

NCR issuance and tracking
Root Cause Analysis (RCA) verification
Corrective action effectiveness validation
Follow-up inspection for closure confirmation

We ensure unresolved issues do not follow equipment to site.

Procurement Quality & Vendor Surveillance Support

Integrated quality support during procurement:

RFQ and Technical Bid Evaluation (TBE) support
Deviation list review and clarification
Expediting and progress monitoring
Release note verification
Quality dispute and claim support

Quality control aligned with procurement strategy.
