Waterway guidelines 2011

The Waterway Guidelines cover only: • the transport engineering design; the structural design is beyond the scope of the Guidelines; • waterways in CEMT classes I to V and recreational waterways; • waterways without currents or with a longitudinal current up to 0.5 m/s; • waterways that are not primarily intended for sea shipping; • waterways other than the shipping lanes in the North Sea or Wadden Sea. Since, in practice, a need for specification of the dimensions and characteristics of reference motor vessels, pushed convoys and coupled units in class VI has become apparent, these have been included in chapter 2. They serve as a basis for the design of class VI waterways. However, given the fact that there has been insufficient research into the translation of class VI into dimensions for waterway sections and engineering structures, the scope of the Waterway Guidelines will remain limited to classes I to V for the time being. Waterways larger than class V can be regarded as exceptional cases, which will always require special investigation. It would not be wise simply to extrapolate the figures in the Guidelines.
