Non-destructive testing comprises a range of non-invasive technologies and techniques to determine the integrity of a material, component or structure; or quantitatively measure some characteristic of an object.

Because it does not harm, stress or destroy the test object, NDT plays a crucial role in ensuring cost-effective operation, safety and reliability which are important factors for any industry; particularly marine and oil & gas.

The single most important factor in NDT is personnel qualification and skill as NDT techniques rely heavily on skill and knowledge for the correct assessment and interpretation of test results.

In this respect, Unidive stands out in the crowd, with internal and external training programmes for its divers and rope access technicians. Unidive is unique in offering testing services topside and subsea. These include:

• Ultrasonic Testing; useful for detecting surface and subsurface flaws in welds, tubing, joints, castings, billets, forgings, shafts, pressure vessels, engine and structural components.
• Eddy Current Inspection; particularly applicable for metals, alloys and electro-conductors. ECI is useful for detecting surface and subsurface flaws on tubing, wire, bearings, rails, non-metal coatings and components.
• Magnetic Particle Inspection; for ferromagnetic materials. MPI is useful for detecting surface and subsurface flaws of welds, tubing, bars, castings, billets, forgings and extrusions.
