Dye Penetrant Testing (DPT), also known as Liquid Penetrant Testing (LPT), is a highly effective NDT method for detecting surface defects in non-porous materials. In the marine and offshore industries, ensuring weld integrity and structural soundness is vital for preventing failures in ships, oil rigs, and marine pipelines.

In key South African coastal regions such as Cape Town and Durban, DPT is widely used to inspect marine components, including hulls, propellers, and drilling structures. The process involves applying a liquid dye, allowing it to seep into defects, and then using a developer to make flaws visible under UV or white light.

National NDT Services specializes in DPT for offshore applications, helping clients meet classification society standards like Lloyd’s Register of Shipping (LRS) and the American Bureau of Shipping (ABS). Our expert team ensures the highest safety and quality standards, reducing risks in marine operations.
