NDT & UWILD Inspections

Professional Non-Destructive Testing & Underwater Inspection Services for Marine and Offshore Assets

Maintaining the structural integrity of marine and offshore assets is essential for safe, efficient, and compliant operations. Over time, continuous exposure to seawater, corrosion, marine growth, and operational stress can gradually affect submerged structures. Therefore, professional NDT & UWILD Inspection Services play a critical role in identifying defects early, supporting preventive maintenance, and minimizing operational downtime.

Supporting marine operations across Abu Dhabi, Dubai, Sharjah, Fujairah, the United Arab Emirates (UAE), Saudi Arabia, Qatar, Oman, Kuwait, and Bahrain, Al Safwan Marine delivers reliable underwater inspection solutions using experienced commercial divers, advanced testing equipment, and internationally recognized inspection procedures.


Why NDT & UWILD Inspections Matter

Routine underwater inspections are essential for protecting marine assets throughout their operational lifecycle. In addition to visual assessments, advanced Non-Destructive Testing (NDT) techniques help identify corrosion, fatigue cracks, coating failures, weld defects, and structural deterioration beneath the waterline.

By combining commercial diving expertise with proven inspection methods, operators can accurately evaluate structural integrity without causing damage. As a result, maintenance activities can be planned more effectively, operational interruptions are minimized, and long-term repair costs are significantly reduced.

Key Benefits

  • Early detection of structural defects
  • Reduced operational downtime
  • Cost-effective alternative to dry docking
  • Improved asset integrity
  • Enhanced operational safety
  • Extended equipment lifespan
  • Regulatory and classification compliance
  • Better maintenance planning

Our NDT & UWILD Inspection Services

Every inspection project requires precision, technical expertise, and strict adherence to industry standards. Accordingly, our experienced commercial diving team provides comprehensive underwater inspection solutions that support safe, compliant, and reliable marine operations.


UWILD (Underwater Inspection in Lieu of Dry Docking)

UWILD inspections allow eligible vessels to complete mandatory underwater surveys without entering dry dock. Consequently, operators can reduce downtime, lower maintenance costs, and continue normal vessel operations while satisfying classification society and regulatory requirements.

Services Include

  • Hull Inspection
  • Sea Chest Inspection
  • Rudder Inspection
  • Propeller Inspection
  • Underwater Structural Survey
  • Inspection Documentation

Ultrasonic Testing (UT)

Ultrasonic Testing measures material thickness and detects internal defects without damaging the structure. Furthermore, this inspection method provides accurate condition assessments for hull plating, offshore structures, subsea pipelines, welded components, and other critical marine assets.

Services Include

  • Thickness Measurement
  • Corrosion Monitoring
  • Internal Defect Detection
  • Weld Assessment

Magnetic Particle Testing (MT)

Magnetic Particle Testing identifies surface and near-surface discontinuities in ferromagnetic materials. Likewise, it is highly effective for detecting cracks, weld defects, and structural imperfections before they develop into significant failures.

Services Include

  • Weld Inspection
  • Crack Detection
  • Surface Defect Assessment
  • Structural Integrity Evaluation

Dye Penetrant Testing (PT)

Dye Penetrant Testing detects fine surface cracks, porosity, and imperfections in non-porous materials. As a result, operators can identify hidden defects early and carry out timely corrective maintenance before more extensive repairs become necessary.

Services Include

  • Surface Crack Detection
  • Weld Inspection
  • Component Assessment
  • Quality Verification

Structural Integrity Assessment

Comprehensive structural integrity assessments combine detailed visual inspections with advanced NDT techniques to evaluate submerged marine structures, offshore assets, and underwater infrastructure. Moreover, detailed technical reports support informed maintenance planning, risk management, and regulatory compliance.

Services Include

  • Structural Evaluation
  • Corrosion Assessment
  • Coating Condition Assessment
  • Technical Reporting
