White Paper: Missing Pipeline Data
Combined effort to provide traceable, verifiable, and complete records.
Mitigating Risk While Extending Asset Lifecycle
With more than 800,000 kilometers (500,000 miles) of inline inspection (ILI) completed, TDW has the experience and expertise to help pipeline owners and operators achieve system integrity and reliability, resulting in an extension of the asset lifecycle. Our dedicated personnel – powered by knowledge and focused on mitigating risk – partner with you to meet rigorous safety, regulatory, operational, and corporate demands.
Our inline inspection technologies are fully engineered to provide you with the most accurate data available – and to detect threats to pipeline integrity in even the harshest environments.
TDW provides a variety of ILI technologies, tools, and services, including inspections for:
Comprehensive threat assessment
Cracks and crack-like anomalies
Corrosion and metal loss
Dents and other anomalies
Additional ILI technologies improve pipeline mapping and produce precise data in certain high flow pipelines:
We’ve also made it easier than ever for you to review and navigate ILI data:
Our high resolution deformation (DEF) tool provides pipeline operators with an easy and efficient way to detect minute bore reductions — including dents, expansions, ovalities, wrinkles, and misalignments — down to the slightest change in the pipeline’s internal diameter.
With natural gas magnetic flux leakage (GMFL) technology from TDW, pipeline operators can harness the accuracy of MFL technology while improving its speed profile, ensuring successful inspections for volumetric metal loss.
The TDW Interactive Report software offers an efficient way to review inline inspection (ILI) results and plan dig programs in a simple, Windows® -based environment.
Pipeline construction contractors have used the caliper technology from TDW to detect large bore reductions in new construction since we introduced first generation KALIPER® tools in the early 1970s. Today, our KALIPER 360 (K360) technology makes the pipeline bore validation process quicker and more cost-effective than ever.
By identifying changes in steel microstructure due to mechanical working or heating, low field magnetic flux leakage technology – known as LFM – helps pipeline owners and operators who have a large number of dents identify and prioritize repair efforts to focus first on the most critical anomalies and lower the probability of pipeline failures.
Since 1997, TDW has provided accurate detection and sizing of internal and external metal loss through high resolution magnetic flux leakage (MFL) technology.
Inline inspection (ILI) technologies can help owners and operators of pressurized pipeline systems identify the greatest integrity threats – and focus their budgets on mitigating the most urgent and critical anomalies.
Designed to enhance inline inspection and give pipeline owners and operators more confidence about inspection results for crack detection, SpirALL® electromagnetic acoustic transducer (EMAT) technology finds cracks (zero width) that magnetic flux leakage-based technology is unable to detect.
With SpirALL® magnetic flux leakage (SMFL) technology, pipeline owners and operators have an easier and more efficient way to detect crack-like defects in the pipe wall and long seams—including selective seam weld corrosion, hook cracks, lack of fusion, and surface-breaking laminations.
High resolution XYZ mapping technology from TDW pairs global positioning system (GPS) coordinates at above-ground locations with inertial mapping. The result: highly accurate data to support your pipeline integrity program.
