Initial Situation

Currently the gas supply in the western and northern parts of Germany mainly consist of L-Gas. As a result of the continuously decreasing L-gas supply, the Grid Development Plan (NEP) will regulate the market transition from low to high caloric gas until about 2030. There is a demand for regional and communal supply networks to make the transition in order to replace gas consumption utilities and assets. Only this will maintain the high quality and safety standards of gas supply.

The gas supply network transition and newly required technical equipment falls within the network supplier’s jurisdiction according to § 19 a 'EnWG – Umstellung der Gasqualität'. The process of refitting technical gas consumer equipment due to gas transition processes has already been carried out and tested by various gas providers. However, the size of the transition as well as the associated technical and logistical challenges remain large. In addition, rising costs are forcing supply companies to evaluate efficient and economical instruments to support the process.

The guidelines form a framework for gas supply companies and support planning processes, carrying out the transitions as well as quality tests. Especially the DVGW Arbeitsblatt G 680 (A) and DVGW Merkblatt G 695 (M) fall under the network provider’s jurisdiction.

Lovion supports market transition processes in line with defined guidelines and offers standardized modules for work management, mobile work and response tools as well as tools for quality assurance. The fundamental software-supported tasks for market transition are:

  • Device registration
  • Planning the equipment retrofitting process
  • Retrofitting equipment
  • Quality assurance

These tasks have to be planned and followed up on.

Device Registration

Creating Registration Tasks

The devices are registered prior to the transition phase in order to plan future modifications. Relevant information and associated data includes affected gas connections, corresponding meter points, meters and gas devices. In addition, base and movement data is recorded as well. Usually this data is not available in the IT-system and has to be imported into the Lovion database via standard interfaces for ERP-systems, GIS and EDM-systems.

Spatial data from GIS can be used to carry out georeferenced tasks, e.g. tasks within a district etc. These also include topological information about the gas network.

With Lovion it is possible to combine available source data and visualizations in one interface.

The information and transition timetable includes affected people from the source system. These include connected customers, energy customers, device operators as well as tenants and property owners.

A registration task always refers to one gas connection. First the task is created based on its source data, before it can be terminated in Lovion and assigned a resource. Tasks which lie within close proximity to one another and have a similar timeframe are combined into work packages. This eliminates unnecessary travel times. Appointments for evaluating devices can be planned as scheduled tasks. In addition, serial post-notifications for scheduled tasks can be created and documented in Lovion.

Carrying out Registration Tasks

The registration task can be carried out by the gas supply company or a service provider. Equipment is registered with the help of the DVGW-Device Database. Information regarding registered devices (currently about 17 000) is also available on mobile devices and online. With the help of quick filters, devices can be matched quickly and accurately.

Unregistered devices can be entered into the database and forwarded to the DVGW using their workflow.

The Registration task consists of numerous subtasks, depending on existing meters and connected gas devices. When the task is dispatched, all subtasks are dispatched as well.

During a registration task, the device is matched with other devices in a database. Furthermore, the serial number is recorded in order to pinpoint the exact model, type and manufacturer including other checkpoints.

Various roles in the process can be assigned to different people. Thus, all relevant employee data including their roles can be captured and supplemented during mobile use. Additional personal data will help to simplify communication in the future.

During the registration process, (status-) data of house connections and meters can be recorded und supplemented with additional data in the system. Furthermore, tasks associated with other assets can be linked, executed or documented (gas pressure regulator, internal pipeline components, meters …).

Completing Registration Tasks

In the last step, the device is categorized according to the DVGW classification system into the following transition groups A, B, C or D. In addition, the device also receives a sticker, indicating the necessity to replace the device. Optionally it is also possible to add barcodes to devices for identifying them at a later stage when the retrofitting process takes place. It is mandatory to document photos of stickers, barcodes and labels along with distinctive features.

Planning the Equipment Retrofitting Process

When planning the equipment retrofitting process, all mobile data is evaluated. Lovion supports the transition stage with a range of filter and report tools that take into account master data, process data as well as spatial information for future transitions.

Equipment Retrofitting

Generating Equipment Retrofitting Tasks

The transitioning of equipment follows after the device registration and data assessment of installed devices have been completed. These also require thorough preparation.

All data required to execute the transition are contained within the Lovion database. Registered equipment is evaluated with the help of the Lovion system and is divided into equipment categories. The material needed to replace equipment is calculated using the database. In addition, a list of necessary material is created and forwarded to the procurement department. Relevant people and affected partners who are involved in the process are informed through customer post-notifications (serial postage). Thus, they are aware about the upcoming transition.

The transition phase is a complex task, which is divided into numerous subtasks associated to the meters and their adjoining equipment. Similar to the device registration process, the tasks are referenced to the house gas connection.

Transition tasks are always referenced to a registered device. Preparations are carried out in the office. Executing the transition depends on affected group components, the district and available resources from Lovion DISPATCH. Resources include company personnel as well as external service providers. The administration of workers is configured in Lovion WORK and Lovion DISPATCH A part of the quality assurance includes the assessment of qualified workers. Tasks in Lovion can only be dispatched to personnel with appropriate qualifications. They are appointment tasks which are coordinated with the respective gas operators. Here again, the standard tools for producing postage and e-mail notifications are used in order to ensure a smooth transition.

Tasks with a similar spatial and temporal context are summarized into task packages in order to prevent unnecessary travelling times. An optional component is to optimize the routing.

Executing the Retrofitting Task

In order to carry out the retrofitting task, the required material has to either be collected from the warehouse or delivered by the service providers. The list of materials forms part of the electronic task.  Lovion ROUTING can be used to improve the efficiency of travelling routes.

Vor Ort dient der bei der Erhebung zugeordnete Barcode der eindeutigen Identifizierung des Gerätes.
Die Umbauarbeiten können begonnen und angeschlossen werden. Alle notwendigen Tätigkeiten sowie die Prüfung und Einstellung des Gerätes für den bestimmungsgemäßen Betrieb werden dokumentiert.

The barcode helps to identify devices on site. Retrofitting the equipment can be concluded. All required tasks as well as testing and altering the settings of the device for operational use are documented.

In order to attain a precise result of the meter reading for the gas quality transition, the meter reading of each corresponding meter point/meter is also documented for distinguishing the billing.

Completing the Device Exchange

Once the exchange has been completed, the device ist marked as such. In addition, further specific details are documented.
The device is labelled with a sticker concerning the exchange. A photo documentation of the sticker, barcode and tag of the is compulsory.

Quality Assurance

Establishing Quality Assurance Tests

After the equipment has been registered, the quality of the completed retrofitting is continuously assed for quality assurance purposes according to the guidelines of the DVGW Merkblatt G 695 (M).

This is a mobile task which incorporates at least 10 % of all retrofitted equipment and at least 10 % of the equipment associated with the equipment group. Tests are performed in line with Attachment B of the info sheet – Examplary test protocol for assessing the performed device registration, refitting and transition measures (English translation)– and can be measured with a point system provided in Attachment A – A point system for assessing the results of gas device tests for refitting and transition measures (English translation).

The gas equipment test tasks for the equipment groups and single components can be proposed by the system or created manually.

Implementing Quality Assurance

This task is carried out in line with Attachment B of the info sheet G 695 (M) – Examplary test protocol for assessing the performed device registration, refitting and transition measures (English translation). During the test phase, the allocated points are based on Attachment A - A point system for assessing the results of the gas device tests for refitting and transition measures. These can be evaluated afterwards.

If a defect is identified during the device exchange, the technician can correct it himself. In special cases, a follow-up task can be created to remove the defect. The device can also be taken out of operation.

Completing the Equipment Assessment

After quality assurance has been concluded, the equipment is labelled as 'completed' and any relevant information is documented. In addition, the device is labelled with a sticker of the quality assurance test. A photo documenting the label, barcode and sticker are mandatory.
