The main highlights of the new release are:

3D data visualisation

  • Changing data in the 3D visualisation while keeping the same viewport;
  • Show the pipeline’s centreline instead of the actual diameter, this improves the visibility for very long pipelines;
  • Show a settlements line;
  • Show distance labels.

Data entry

  • Reference identifiers now possible with input tables PIPES, SUPPORTS and SISPRC;
  • Increased flexibility to define additional identifiers.


  • Latest NEN 3650-1+C1:2017 confirms the calculation method of the upward vertical soil stiffness for deeply situated pipelines as applied by the Soil Model Wizard of Ple4Win;
  • Underlying calculation methodology modernised.

Courses for Ple4Win users

The performance, accuracy and speed of a project calculated using Ple4Win depends for not a small part on how the project is modeled. More often than not, a good pipeline model has greater benefits than e.g. a faster computer and may prevent lots of calculations on model variations. We are planning to provide for a course on the art of making a good functional pipeline model. This half-day course is primarily intended for experienced users.
