Norwegian inspection specialist KTN has become a full member of Swiss global integrity solutions provider Rosen Group.
KTN specialises in in tethered ultrasonic self-propelled solutions for the inspection of unpiggable assets and for the past five years has worked with Rosen to provide in-line inspection services for challenging pipelines. It will now provide services under the Rosen brand. Rosen says that the new strategic alliance extends its technology and increases the possibilities for customised solutions for challenging pipeline diagnostics.
Rosen and KTN will offer self-propelled tethered inspection units with ultrasonic testing (UT) and time-of-flight diffraction (TOFD) technologies as well as additional resources for feasibility studies. The tethered in-line inspection method enables the collection of high-quality data on pipeline integrity status based on various features, including propulsion units that can be remotely controlled in both forward and backward motion as well as speed adjustments, precise high-resolution geometry, wall thickness / corrosion and crack measurement with reliable pulse-echo UT technology and a live tether, which provides unlimited power supply and transmits real-time data back to the system operator.
Rosen says that as well as creating customised solutions, the services added to its portfolio include ultrasonic geometry inspection (diameter variation, dents, ovalities), ultrasonic corrosion/wall thickness inspection (normal beam, pulse-echo), ultrasonic axial and circumferential crack inspection (angular beam, pulse-echo, shear wave and TOFD), eddy current technologies for corrosion and coating, visual inspection with CCTV camera (in visible products), and XYZ mapping services.
‘The decision to offer solutions under one brand was made to ensure operators are best supported in customising solutions for their pipelines. No personnel changes will be made and services will continue to be provided by trusted experts,’ says Rosen Group.
