Speir Hunter

Speir Hunter Ltd, in partnership with the University of Leeds in the UK, has engineered the science of stress-magnetisation to create a remote pipeline inspection tool which is used by integrity engineers worldwide on both piggable and non-piggable lines. This groundbreaking technology is called Stress Concentration Tomography, commonly referred to as SCT™ or Large Standoff Magnetometry (LSM). Using SCT™ enables pipeline integrity managers to fully understand the condition of their assets by providing vital information including: - Abnormal localised stress areas - Accurate pipeline positioning coordinates - Accurate pipeline depth of cover - Accurate locations of changes in pipeline diameter and wall thickness - Accurate locations of illegal hot-tapping - Accurate condition of pipelines in geo-hazard environments SCT™ deliverables provide a pipeline integrity engineer with a plethora of valuable information to support them in making time-critical operational decisions, as well as enabling them to monitor pipeline condition changes over time. SCT™ offers a way to improve an operator's financial and operational efficiency. Use SCT™ to: > screen pipelines in order to determine areas for further investigation with high-resolution tools > monitor the growth of known areas of corrosion, reducing the need for longer In-Line Inspection runs > determine areas subjected to abnormal stress as a result of geo-hazard conditions, including slippage and subsidence > reduce unnecessary costs by excavating precisely the right location thanks to our sub-meter accuracy GNSS system > save money by limiting excavations to pipeline sections with corrosion present underneath reported coating damage No need to interrupt material flow within an operational pipeline, or introduce any type of additional energy into the network in order for an SCT™ inspection to take place.
