Gas networks - Import export

With an electronically supported gas pipeline network survey, you have the following advantages: You take full advantage of the possibilities of your GIS. You reduce your effort considerably. You increase efficiency and security through digital documentation. You create better predictability and advantages for your work preparation You significantly increase the quality of the documentation

Easy-to-use, mobile carpet probe with surface plate, bag filter, hose and plug-in coupling for surveying pipelines, and for recording gas traces after checking the gas pipeline network with the suction process. Very light, therefore fatigue-free and easy to use in daily tasks. The wide edge of the flexible carpet probe conforms well to unevenness on the pavement surface and largely prevents the ingress of interfering gases (exhaust gases) during the inspection process.

Other areas covered by our dedicated divisions may also be involved in the execution of public and private works. Examples include the treatment of the soil on site, the connection to energy or utilities networks (electricity, gas, water, telecommunications), the installation of linear elements, urban furniture or road signage, various plants and fences, public lighting or even road marks.

The Leaksurveyor uses a fast response semiconductor sensor reducing the time taken for gas leak surveys on gas distribution networks. The Leaksurveyor detects flammable gas from PPM through LEL to 100 % Vol. Integral Semiconductor Sensor (Range 0 – 10,000 ppm), providing fast response leak detection PPM , LEL and volume flammable gas ranges for leak detection, general safety monitoring and barholing Audible and visual ‘Geiger’ alarm indication on ppm range Integral pump with pressure sensor for flow fail detection with sample path protected by hydrophobic filter

Analysing the gas quality in the gas network is essential to monitor technical specifications and ensure correct billing. The GasPro is a mobile gas sampler, with which cyclic sampling can be carried out easily and flexibly at any point from dry gas networks. The samples are collected in a sample cylinder in the GasPro and can then be analysed in a laboratory. The GasPro allows the separation of sampling and sample analysis and is therefore more cost effective and flexible than for example fixed installed gas chromatographs.

Used widely in electricity substation maintenance, Smartfill provides a simple, efficient, zero emission alternative to manual filling and top-up of SF6 compartments. Filling of newly installed SF6 assets and refilling of in-service assets can be achieved automatically during live energised operations. Topping up leaking or damaged SF6 assets can also be completed without an engineer. Designed to accurately measure, control and monitor SF6 gas passing through the network, this smart solution delivers compliant measurement of SF6 inventory and usage with complete traceability.

With the development of CHARM®, Open Grid Europe is providing an efficient leakage control method for natural gas pipeline networks and thus an alternative to the labour intensive practice of conducting on-site inspections of the pipelines with gas detection devices. CHARM® is a highly accurate infrared laser system integrated in a helicopter that is capable of precisely detecting even very low methane concentrations from the air. Even in the case of very complex pipeline topologies, the course of the pipeline can be detected consistently on a large scale during the flight by an automatic, highly precise scanning beam control system (autotracking), thus ensuring a reliable leak tightness inspection of the natural gas pipeline.

Maintenance and repair work on the natural gas network is generally carried out with the pipeline being gas-free, so the relevant pipe sections are isolated by installing valve assemblies and the gas in the isolated section is vented to atmosphere. By using our mobile compressors – individually or in highly efficient parallel operation – the network operator can transfer the gas from the isolated pipe section to another part of the system so it does not have to be vented to atmosphere. Connection points for the mobile compressors are available e.g. in the area of the main line valves or can generally be retrofitted. It makes economic sense to transfer the gas to another as this guarantees responsible handling of this primary energy source and makes a substantial contribution to protecting the environment. Services offered: Pipeline recompression until lowest residual pressure < 3bar Reduction of methane emissions by up to 95% Responsible handling with primary energy

Renewable energy sources like solar and wind are ideal for powering equipment in remote locations. These types of off-grid systems are commonly used to power equipment for a variety of different industrial applications. Common applications include lighting, wireless surveillance cameras, sensors, environmental monitors, traffic signals, oil/gas pipes network, pump stations, telecommunication equipment, and anything else that requires reliable power in a remote location. NSBox-SUN Outdoor Access Node is used to deploy protected autonomous or semi-autonomous outdoor applications in the area with no 24/7 electricity available and solar panels can be installed. Typical application for NSBox-SUN is wireless surveillance system that is powered from street lighting where AC power is available only at the night time. NSBox-SUN can be even used if there is no AC power at all if PDs connected to it have low power consumption that can be filled up with energy
