Extended Description:

IVG is owner / operator of an undergound hydrocarbon storage facility in Etzel, Lower Saxony. IVG decided in 2007 to expand the gas storage capacity in order to provide a strategic gas reserve connected into the north german gas network. For this purpose, an increased capacity transmission pipeline was constructed between Etzel and the trade hub at Bunde (near the Dutch/German border). The pipeline and stations were designed for bi-directional operation and quick start-up to allow spot trading. BEP was set up to develop and eventually operate the pipeline and associated stations.

The scope included:

  • 60 km, 48“
  • 3 line valve stations
  • Tie-in to caverns piping
  • Scraper station
  • Auxiliary and utility systems
  • Civil infrastructure
  • Scraper station
  • Custody metering, including filters
  • Pressure and flow control
  • Valving to permit bi-directional operation
  • Auxiliary and utility systems
  • Civil infrastructure
