Erdgas Münster controls pipeline network with KEYMILE systems technology

Hannover - Erdgas Münster, a major German remote gas company, has selected KEYMILE systems technology to monitor natural gas transmission. As a result, remote maintenance and control of the pipelines will be much more efficient and cut operating costs.

For over 50 years, Erdgas Münster has been supplying its customers with natural gas that is almost exclusively from North German fields. The complex pipeline network that has evolved over the years is over 2,200 km long. It connects to the north German natural gas fields and is located primarily between Bentheim, Emsland and the Hanover, Göttingen and Wendland region.

The control centre in Münster monitors and controls the gas flow. The centre also supervises the blending and distribution stations. Due to the increasing demands on operation and monitoring the supply network, Erdgas Münster decided to introduce a new, advanced solution and has opted for KEYMILE systems technology.

Data and information from production, the blending and distribution, as well as the transfer stations, are transmitted to the control centre in Münster via cables along the gas pipelines. The new solution, based on KEYMILE technology, supports continued monitoring of the process and creates the basis for reliable telecontrol system communication.

In this case, the multi-service access platform UMUX, as well as LineRunner SCADA NG are used. LineRunner SCADA NG is a broadband transmission system for reliable data transmission in telecontrol and SCADA networks (SCADA:

Supervisory Control And Data Acquisition). UMUX enables connection to copper and fibre optic line networks, multiplexing, switching data streams and broadband data aggregation for TDM and Ethernet data in just one single network component. This reduces the complexity of the transmission network.
Therefore, Erdgas Münster can continue to utilise the existing infrastructure for data and voice services and can also handle new packet-based services. LineRunner SCADA NG is applied if accurate data transmission is required in tough ambient conditions and where space is limited.

"Sophisticated DSL transmission technology, as well as the integration of the traditional interfaces in packet-based transmission technology, allows Erdgas Münster to continue to use existing copper wire effectively and efficiently. At the same time, KEYMILE technology means we are extremely well prepared for future telecontrol technology modifications", explains Hans Lange from the Measurement and Control department at Erdgas Münster.

"There were many reasons why we chose KEYMILE. Right from the concept development phase, the company's customer focus and technical expertise impressed us. Specific demands on the products used were implemented quickly. Another convincing argument was the references for the UMUX platform, from the railway companies in Switzerland for example".
