What holds an offshore wind jacket together for 25 years?
 
More than a kilometer of welded seams, all exposed to complex fatigue loads in a harsh subsea environment. Every one of those welds has to be right, and it has to be provable.
 
This is where non-destructive testing (NDT) comes in. Different NDT methods can be used to identify defects without damaging the material, including:
 
➡️ Ultrasonic Testing (UT) – detecting internal defects
➡️ Time of Flight Diffraction (TOFD) – precise weld inspection
➡️ Magnetic Particle Inspection (MPI) – detecting surface and near-surface
defects
 
Together, these methods help catch problems before a structure ever leaves the fabrication yard.
 
At TN | Technica Nova GmbH, our QA/QC teams work on site to witness these inspections, verify that procedures and personnel qualifications meet the project specification, and review the resulting reports before final sign-off. Good NDT is only as reliable as the process around it.
 
Careful oversight during fabrication saves far more time and cost than fixing an issue after installation.
