ROSEN has announced that it will present its new approach for pipe properties and a maximum allowable operating pressure (MAOP) validation at this year’s Pipeline Pigging & Integrity Management Conference (PPIM).
Many pipeline operators face uncertainties regarding the unknown specified minimum yield strength (SMYS) of the pipeline material, which is fundamental factor needed when establishing a maximum allowable operating pressure (MAOP) of a pipeline.
At the PPIM, ROSEN will present how its unique integrated approach is capable of fulfilling these requirements to determine pipe properties and therefore support the process of validating the MAOP, either comprehensively and / or holistically.
This turn-key deliverable comprises of three complementary activities, namely: (I) Review & alignment of existing pipeline information, (II) utilisation of existing pipeline data and (III) the RoMat PGS service with a novel ILI technology used for pipe grade determination.
All gathered information is prepared for easy integration into a geographical information system (GIS) and to be further processed in an integrity management system (IMS). During data integration a comprehensive alignment of records is provided.
All information can then be further processed in an asset integrity management system (AIMS) such as ROAIMS.
The combination of these activities is adjusted to project specific needs and aligned to the US Department of Transportation Pipeline and Hazardous Materials Safety Administration’s (PHMSA) drafted integrity verification processes (IVP) for pipeline safety.
With ROSEN’s unique integrated approach, an answer has been found for the growing demand for pipeline records which need to be verifiable, traceable and complete.
New RoMat PGS ILI Service
To perform meaningful calculations as part of risk assessment programmes or fitness-for-service assessments, operators require accurate design information for each and every pipe joint for a given diameter, wall thickness, steel grade, and seam type to determine the MAOP.
Conventional ILI technology provides valuable pipeline information for MAOP calculation, however it does not provide pipe steel grade data.
The steel grade of a pipeline and its subsequent specified minimum yield strength usually has to be determined through costly field verifications and additional tests, which is also a limited sample and may not be indicative of the entire pipeline.
Now ROSEN has developed the world’s first inline inspection service capable of continuously identifying and differentiating the pipe steel grade. In comparison to other statistics analysed by ‘in the ditch’ methods, the firm’s new service delivers a high-resolution strength profile of the entire examined pipeline section. This makes ROSEN RoMat PGS ILI service unique.
The ILI service also comes with a number of key advantages. This includes pipe steel grade determination without costly excavations / field verifications, completion of pipeline data records, and compliance to regulations.
It also provides lifetime integrity management supported by full recording of the inspection raw data, as well as high-quality service with certified processes (API 1163), personnel qualification (ASNT) and equipment (CE, ATEX), and high availability and a wide range of proven tool configurations addressing individual operational pipeline requirements.
ROSEN’s next challenge will be to determie the pipeline toughness.
In the meantime, the firm invites attendees at the event to visit the ROSEN booth to discover how "We close the Gap" and serve the industry to ensure pipeline records to be traceable, verifiable, and complete.
