In the Offshore, Oil & Gas, and Industrial sectors, early defect detection is essential for ensuring equipment safety, quality, and reliability.
OTS provides Non-Destructive Testing (NDT) services to inspect materials, welds, and steel structures without compromising the integrity of the product, helping customers maintain quality throughout every stage of their projects.
What is Non-Destructive Testing (NDT) and Why Is It Important?
Non-Destructive Testing (NDT) is a group of inspection methods used to detect surface and internal defects without damaging or altering the product.
In the offshore industry, early defect detection plays a critical role in ensuring equipment quality, reliability, and operational performance. NDT enables the inspection of materials and welded joints, supporting quality control, project acceptance, and compliance with technical requirements while preserving the integrity of the inspected component.
NDT Services at OTS
OTS provides Non-Destructive Testing services for a wide range of equipment and steel structures used in the Offshore, Oil & Gas, and Industrial sectors.

NDT Methods at OTS
Depending on project specifications, OTS applies various Non-Destructive Testing methods to evaluate the quality of materials and welded joints.

Figure 13: Non-Destructive Testing (NDT) Methods
Our inspection capabilities include:
- Magnetic Particle Testing (MT) – Detects surface and near-surface defects in ferromagnetic materials.
- Liquid Penetrant Testing (PT) – Identifies surface-breaking cracks and discontinuities.
- Ultrasonic Testing (UT) – Detects internal defects in materials and welded joints using ultrasonic waves.
- Eddy Current Testing (ECT) – Evaluates surface and near-surface defects in conductive materials.
The appropriate inspection method is selected based on the technical requirements and specifications of each project.
