Analysing Pigrun Data

Defect assessment

Association defect data with pipeline properties, survey data, soil acidity, CP history, coating type, age

Can carry out calculations / retrieve information on mechanical strength (e.g. B31G, RSTRENG)

Supports the selection of pipe surface area to be investigated

Includes and presents the effect of defect interaction on the remaining strength of the pipeline segment

Make a 3D view of any of the defects based on raw ILI-pigrun data

When more pigruns have been carried out, the system can present the 3D picture of the same defect as been measured by the different pigruns

Can manage all in-line inspection data for an entire pipeline grid

INPIPE

InPipe is a unique tool that allows the operator to quickly access data, browse in a convenient form, recognize problem areas and switch to a close up view of selected flaws.

The assessment of defects in InPipe is based on the science of fracture mechanics.

InPipe supports the calculation of remaining strength of the pipeline as defined by different codes. Raw data functionality enables the automatic calculation of remaining strength using a less conservative method, which approximates to Rstreng calculations. This will create savings by postponed repair programs whilst maintaining the required level of safety of the pipeline.content.

InPipe provides functionality that enables accurate positioning of in-line data along a three-dimensional model of the pipeline. Dynamic stretching/shrinking of the in-line data enables an optimal fit of all feature positions on the existing pipeline (drawings) in the system. This type of data processing is a critical component because it accurately links underground assets with surface objects and linear based data sets like survey- and CP- data. This process is highly automated in InPipe; however it still requires manual input from the engineer, particularly in the classification of reported defects.

Once this classification is completed, the end-user can analyse the density of defects with the help of various charts and diagrams, such as pipeline profile maps, crossings maps, electrochemical protection diagrams, and soil profiles etc.

DEFECT ANALYSIS

The result of analysis supports the engineer in the prioritisation of pipeline repairs. For each defect, the system can provide the exact location along the pipeline, the distance from the defect to other objects of the pipeline as well as to geodesic objects, and can generate a "Defect Properties Card". The system is able to store information on the repaired defects and to analyse this information.
