Ultrasonic Phased Array testing of bolts and studs in-situ (to aid our customers in quick, reliable and reproducible defect detection while still in service) is something we’ve been successfully doing for quite some time now. But due to the increasing demand for this form of inspection in the offshore and wind sector, and to underline our joint expertise with Control Union, we’ve had our examination procedure validated and approved by DNV-GL.

In order to acquire consistent field data we utilize our own designed scanner mechanism, which is a compact and low-profile hand-manipulated scanner that allows us to inspect bolts and studs of various diameters and lengths. The low and narrow profile ensures a wide range of employability and in-situ inspection flexibility.

Typical inspection applications are;

  • Slewbearing ring studs.
  • Flange bolts.
  • Riser system bolts.
