Scientific Principles of Ultrasonic Testing

High frequency sound waves are sent into a material by use of a transducer. The sound waves travel through the material and are received by the same transducer or a second transducer. Both the amount of energy transmitted or received and the time it takes are analysed to determine the presence of flaws. Changes in material thickness, and changes in material properties can also be measured.

Main Uses

Used to locate surface and subsurface defects in many materials including metals, plastics, and wood. Ultrasonic inspection is also used to measure the thickness of materials and otherwise characterize properties of material based on sound velocity and attenuation measurements.

Main Advantages of Ultrasonic Testing

depth of penetration for flaw detection or measurement is superior to other methods;

only single sided access is required;

provides distance information;

minimum part preparation is required;

method can be used for much more than just flaw detection.

Inspections & Surveys

At Ned Marine we provide comprehensive inspections and surveys for many of our clients. Do you want to assess the condition, safety, and compliance of your vessels, offshore structures, or industrial assets? Our certified surveyors conduct pre-conditional surveys, special surveys, and hull inspections, identifying structural issues, corrosion, or coating failures before they become costly problems.

We work globally, on land, in dock, and at sea, ensuring compliance with classification societies and industry regulations. Whether for preventive maintenance or regulatory requirements, our inspections deliver clear, detailed reports to help you make informed decisions and maintain operational excellence.
