Debris Removal
The accumulation of debris in pipelines is a common problem but a difficult one to manage safely and effectively. Typically, we think of debris as sand deposited during production or construction, but it can also include mechanically recovered scale, corrosion, and even welding residues.
While mechanical scraper pigs are effective at debris removal, they carry a significant risk of sticking when debris volume is high relative to the pipeline diameter.
Another complicating factor is that it is difficult to accurately estimate the amount of debris in the pipeline and how it is distributed, creating uncertainty and operational risk. These challenges are amplified in crude oil lines, where debris is often oily, sticky, and compacted.
Together, they highlight the need for cleaning approaches that can mobilise and remove debris while reducing the risk associated with conventional pigging.
