features Client Gastransport Services Location Eems estuary, The Netherlands Period 2002/2003 IntroductIon The 42” Eems pipeline is part of the pipeline connection between the gas cleaning and drying plant of Phillips Petroleum at Rysumer Nacken in Germany, and the natural gas pipeline network in the Netherlands. The gas is obtained from the Ekofisk gas field in the Norwegian region of the North Sea. The pipeline crosses the morphologically dynamic Eems estuary over a length of 4 km, passing both the deep shipping lane ‘Oostfriesche Gaatje’ and the shallow sand bank ‘Paap’. Since the installation of the pipeline, the Eems’ strong currents have exerted a strong scouring effect on the edge of the sandbank. Over the years, this has resulted in the recurring exposure of a 500 m
