50 years Ple4Win anniversary
On October 1, 2015, we celebrated the 50th anniversary of Ple4Win, more specifically that 50 years ago the necessity arose to calculate the behaviour of buried pipelines in soft soils.
Meeting at the historical fortress Wierickerschans, a presentation was given about the difficulties the Dutch Gasunie encountered when they wanted to cross the nearby Dubbele Wiericke with a 36″ high-pressure gas pipeline in 1965.
The construction finally used was too conservative (and too expensive!) for all practical purposes, but almost nothing was known about pipe-soil interaction then. So the necessity to explore the behaviour of buried pipelines was pressing, and this was the starting point for developments that finally led to the Ple4Win program of today.
