T.D. Williamson (TDW) provides pigging, intervention and isolation, and integrity solutions to help operators of pressurised pipeline systems keep the world’s energy lifelines running safely, efficiently and reliably.
As a natural result of use and the unavoidable deterioration of seal material over time, the repair or replacement of valves on offshore natural gas platforms is inevitable. Often, the need for repair or replacement is identified through planned inspection and testing.
To evaluate the effects of squeeze-off procedures on Polyethylene (PE) pipes, integrity testing using microscopy is vital. This analysis sheds light on the structural changes and potential damage caused by both proper and improper squeeze-off techniques.
Humans use five senses to experience the world. Similarly, pipeline integrity is enhanced by combining multiple integrity data streams (MFL, SMFL, LFM, GEO, XYZ) for comprehensive anomaly inspection. Case studies show improved detection, classification, and sizing of various anomalies.
This paper discusses the validation of a classifier that distinguishes between selective seam weld corrosion (SSWC) and general corrosion crossing the long seam (CCLS).
