NDT – Advanced Techniques



On completion of the training program, the student will be awarded:

→ A Certificate of NDT – Advanced Techniques, issued by Bureau Veritas Solutions Marine & Offshore.

The Certificate of NDT – Advanced Techniques, is obtained after completing the course and passing the online test.


This training course gives a general presentation of the three Advanced NDT Methods (Time-of-Flight Diffraction (TOFD), Phased Array Ultrasonic (PAUT) and Digital Radiography (DR)), their basic principles and how the corresponding equipment should be used in accordance with the testing procedure to ensure the quality of the test performance and testing results.


Whom the course is for

The course NDT – Advanced Techniques is aimed at anyone interested in getting familiar with this NDT technique. This may include Ship Managers, Technical Superintendents, Ship Masters, Officers and Seafarers; Offshore Units Operators and technical staff; Shipyards Technical Staff; Surveyors; P&I and/or Insurance Inspectors; etc.


On completion of the training, students will be able to:

  • Understand the setup and principles of advanced NDT techniques in comparison with conventional methods.
  • Know the testing procedure and the inspection process referred to the equipment used.
  • Differentiate applications according to the advantages and limitations.
  • Get familiar with the aspects of test performance and obtained testing results.
