PIPEJACKING BLOCKBUSTER

This article describes the use of a Herrenknecht pipejacking machine to jack 2.6km of pipe under tidal mudflats off the north coast of Germany from a single jacking pit. The pipe has external diameter 3.8m and internal diameter 3.2m. The tunnel provides the landfall section of the new European natural gas export line from the gas fields of Norway. It runs from its working shaft, in a field behind the coastal dike, to a tie-in chamber in the sea channel. The tunnel is 6-8m below the surface, and was needed to protect part of an environmental sanctuary and national park. Tunnelling began on 1 February 1994, and was completed early in July 1994, when the machine was retrieved from the tie-in chamber. The Herrenknecht machine had the highest specification, with several design features included specifically to meet the job's potential challenges. It was operated completely by remote control, using advanced electronics and computing systems.
