Dynamic models of infrastructure behavior
PIPELINE INFRASTRUCTURE DESTRUCTION: ASSESSMENT AND PREDICTION
CURRENT PROBLEMS IN THE OPERATION OF PHYSICAL ASSETS
The impetus behind the development of our dynamic infrastructure models was the deteriorating state of the physical assets around us and the growing risks associated with their operation. These assets were mainly built in the era of industrialization between the 1950s and the 1980s, and their general aging is aggravated by a common lack of skilled personnel.
The digital modeling of infrastructure deterioration allows us to increase the reliability, safety and operating efficiency of our physical assets.
It highlights the areas where deterioration may occur and the remaining service life of each infrastructure element. It also provides recommendations for optimal maintenance and integrity management and suggests a repair program.
PURPOSE AND FEATURES
The dynamic modeling of infrastructure behavior is designed to monitor, evaluate, analyze, and predict the condition of a physical asset.
  • Attention to detail
    The elemental granularity of digital twins considers individual structural elements, their connections, and their operating conditions. This level of granularity provides high accuracy in identifying failure times and areas based on actual deviations of strength and durability indicators.
  • One - digit key metric - destruction time
    The digital twin is enriched by data streams for
    • The control of linear and angular accelerations of the structure,
    • Previously studied defects and information on the measures taken on constant and variable operational loads,
    • Environmental conditions.
  • Data
    The digital twin is enriched by data flows such as:
    • Linear and angular acceleration control,
    • Previously known defects and measures taken,
    • Constant and variable operational loads.
  • Early warning
    • The digital twin helps to identify and prevent potential failures and bottlenecks that reduce the safety and reliability of the infrastructure asset at all stages of the life cycle.

HOW IT WORKS

1. Collecting and digitizing infrastructure documentation
2. Performing Instrument measurements at the control points
3. Estimating strength, durability, and lifespan of infrastructure elements
4. Reporting on potential failure times and areas. A 7D model is created
The digital journal of elements and their constructive relationships comes as a result of this stage.

The journal is a simple Excel spreadsheet with good readability and editability, ready for further machine processing.

COLLECT AND DIGITIZE THE DOCUMENTS

We digitalize
Hard-copy diagrams and schemas
The initial information can be extracted from project design documents that were only available in paper format.
We create an initial model:
Electronic diagrams and schemas
This stage involves preliminary analysis and the building of the "ideal" mathematical construction model. It involves the assessment of expected loads and stresses, as well as the identification of deviations that can provide useful information about discrepancies between the design and the actual condition of the object (unauthorized pipe cutting, impairment, etc.).
Digitize of defects and events
Operation logs
Dynamic modeling isn't just a flaw detection method. Its purpose is to integrate information into a single model, including data on previously identified issues, and also to rank the elements and defects by the degree of hazard.
We select measurement location:
Control points
Linear and angular displacement probes are used to identify the current condition of the various elements of an asset. The information about movements is collected selectively at the control points of the branching structure. The displacement of all other elements can be restored from these points.
We split to speed up the evaluation:
Structure diagram
For large branched structures, the object can be divided into several sections to speed up the evaluation process. At the same time, this split does not affect the integrity of the assessment of the behavior of the structure as a whole.

We visualize the elements:
Primary 7D model
Primary visualization is one of the key results of digitizing an object. We have developed special software to visualize physical assets perfectly. Unlike BIM modeling tools, the Digital Twin interactive software tool provides open and well-documented specifications of infrastructure assets, including connections and defects.

Measurements

At this stage, linear and angular accelerations are measured at control points. Measurements are carried out to assess actual dynamic loads and compare them with the designed model of the object.

The amplitude-frequency of these loads serves as a unique way of identifying objects and as a basis for the further calculation of displacements.

STRENGTH AND DURABILITY ESTIMATIONS
The measurement results are integrated with construction diagrams into a dynamic mathematical model of the object (the digital twin). The model will help to determine the area and time of destruction for each element.
