Abstract
    In navigation areas with bottoms covered by a fluid mud layer, the nautical bottom concept is introducedto assess the under keel clearance and the level of dredging. Up till now the nautical bottom has alwaysbeen defined using the characteristics of the mud layer. However, criteria based on ship behaviour mayresult in a more efficient definition of the nautical bottom. A mathematical model formulation for shipmanoeuvring in muddy areas, based on systematic captive model tests is proposed. Full mission shipmanoeuvring simulator runs were carried out to review the nautical bottom concept in the harbour ofZeebrugge, Belgium; a selection of simulation results is presented.
