Stadtwerke Düsseldorf: SeCuRi SAT gas leak detection

Dusseldorf/Paderborn, April 2006

SeCuRi SAT is used for the first time this year by the Stadtwerke Düsseldorf AG. The gas pipelines of the North-Rhine/ Westphalian state capital are systematically examined for leaks. The basis is the 1,461 km long low pressure gas network, which is documented in Smallworld GIS and stored on a colibri Tablet PC.

The mobile devices are connected directly to gas leak detection technology (PortaFID) and to a GPS unit.With SeCuRi SAT the gas leak detection profits from the fact that no more paper maps must be carried and that all measured values are automatically documented. Increased values are visually highlighted in a chart.

"We expect a particular advantage from the digital collection and documentation of the pipeline inspection in accordance with DVGW worksheet G465" explains Ulrich Karl of Stadtwerke Düsseldorf.

The results of the inspections are downloaded into the Smallworld GIS over an integrated interface and are available for the planning of preventive maintenance work and redevelopment planning. In Smallworld GIS the SeCuRi SAT Smallworld Server is used as a complement to the mobile solution.

The test intervals are also optimised: "In the inspection districts that we have formed we are now able to differentiate between districts with high and low damage rates in a manner that can stand up in court and we can adapt inspection intervals to actual line conditions. If you consider that in the past, in districts with an increased damage rate the entire district was always subject to shortened intervals between inspections, this saves substantial effort. Today this only applies to the actual areas involved.We are completely in conformance with the G465".
