Non-destructive testing (NDT) plays a crucial role in maritime industries by allowing for the inspection, monitoring, and maintenance of critical structures and equipment without causing damage. In maritime applications, NDT techniques are employed to assess the integrity of materials and components such as hulls, pipelines, offshore platforms, and structural elements of ships.

Common NDT methods used in maritime contexts include:

1. **Ultrasonic Testing (UT)**: UT involves sending high-frequency sound waves into a material to detect flaws or measure thickness. It is particularly useful for inspecting welds, hull plates, and other structural components of ships and offshore structures.

2. **Radiographic Testing (RT)**: RT uses X-rays or gamma rays to examine the internal structure of materials and detect defects like cracks or inclusions. This method is suitable for inspecting thick sections of steel in ship structures.

3. **Magnetic Particle Testing (MT)** and **Dye Penetrant Testing (PT)**: These methods are used to detect surface-breaking defects such as cracks, seams, or other discontinuities in materials. MT involves applying a magnetic field and particles to detect flaws,
