Evaluating and analysing Pipeline Networks
The transition from the German land register to the new official geographic reference system ETRS89 in 2009 has worldwide effects on users who work with this geodata. Asset data associated with supply outages has to be transformed into this geographic reference system. TRAFO89 supports the transformation process by implementing external software. A data migration is not required for the transformation process.
- Analysis of the network topology and structure
- Topology or aerial-related reports
- Summary of pipeline network length for each district
- Pipeline network areas are visualised in colour
- Results can be filtered and exported in MS Excel
The product line of the ITS Pipeline Network Analysis is comprised of different modules:
- Pipeline Analyser
- Pipeline Visualiser
- Pipeline Statistics.
The base module Pipeline Analyser depicts materials, dimensions and pipeline fittings in their topological order across a pipeline route. Starting at a specific network point (plant node, junction or endpoint), the route to the nearest node is analysed including its length, the order of pipelines and respective components as well as grid connections along the route.
The product Pipeline Visualiser is an extension of the Pipeline Analyser and evaluates branches of the pipeline network. In comparison to individual routes, branched networks don’t offer a metrication of individual network assets, but rather an analysis of connected network areas. The simplest variant of the Pipeline Visualiser analyses network areas in between valves, i.e. the smallest network area that can be isolated by closing off valves. If these areas are displayed in different colours, field workers can easily identify the location of the nearest valve on a paper plot or in Lovion BIS when a disruption occurs. The GIS identifies grid connections that are affected by a supply disruption. Larger network areas are called sections. By labelling valves as section valves (standard model for Smallworld sector-specific applications for gas and water), inspection districts and rinsing districts can be depicted.
Pipeline Statistics provides information on gas and water pipeline networks that is not directly related to network topology. Pipeline Statistics incorporates extensive lists of pre-configured reports and queries that can be selected via a menu and are exportable in various formats. In contrast to standard object queries in Smallworld GIS, these queries and reports don’t have to be configured before they are used. Furthermore, Pipeline Statistics collects data from various objects. For example, the statistics of pipe fittings also show the amount, material and dimensions of connected pipelines. In addition, statistics can be displayed for the entire network or for individual network areas. Pipelines that intersect network areas are proportionally taken into account for targeted network areas. Using aerial-based Pipeline Statistics, you can easily create work documents for individual districts, for example a list of hydrants. Furthermore, coordinates for points of interest, for example regarding sector-specific elevation points, can be created and exported. The module Pipeline Statistics also offers a printing function via Microsoft EXCEL. Exported lists are formatted using VBA-Makros and can be modified for various types of statistics. The main advantage of the solution lies in the combination of Pipeline Visualiser and Pipeline Statistics. The results of a Pipeline Statistics report can be used for a network area that was topologically evaluated by the Pipeline Visualiser.
A list of grid connections for districts can be exported containing locations of hydrants or the total length of pipelines or materials as well as dimensions for each street.
