natural gas pipeline

Construction work on the Sannerz-Rimpar natural gas pipeline finished

Railway crossing near Mottgers completed
Pipeline now fully operational

The natural gas pipeline from Sannerz to Rimpar has now been completed, and all remaining construction work on the railway line crossing near Mottgers has finished. As of now the pipeline is operational and ready to transport gas. Work on building the approx. 67 km long gas transmission pipeline with a diameter of about 1 metre and a system pressure of 100 bar began in March of this year. Now that it is complete, the pipeline will be able to transport up to 2 million cubic metres of gas per hour. In all, Open Grid Europe has invested around 125 million euro in the line and in the build of a new gas pressure measuring and regulating station at Rimpar.

"We were able to complete the construction work on the railway crossing near Mottgers before schedule," explains an evidently pleased André Grassmann, Open Grid Europe's project manager, who thanked residents for their patience and forbearing given that some of the work was carried out around the clock.

The process of microtunnelling to allow the product pipes to pass beneath the railway line using the trenchless method involved substantial civil works, with a hole approx. 100 metres long having to be bored in red sandstone. Some 20,000 cubic metres of rock were excavated for the 22 metre deep starting trench.

The remaining land restoration, revegetation and finishing work will be carried out either now or next spring depending on weather conditions. The "Sannerz-Rimpar" line which was initially built following the Open Season in 2008 has been laid out as a loop running broadly parallel with the existing "Rimpar-Schlüchtern" pipeline, and is used among other things to supply regional customers (municipal utilities, industrial companies) in Bavaria and Hesse. The line represents an important link in the European gas transport network. Open Grid Europe is using additional north-south capacity to ease network congestion and so improve gas transport both within Germany and internationally.
