| Abstract |
Due to the scale enlargement in the maritime fleet the accessibility of existing harbours worldwide is getting more and more complex. To reduce infrastructural and operational costs for the adaptation of these harbours the knowledge of ship behaviour in horizontally and vertically restricted channels and waterways helps in designing a cost effective access channel. Ship manoeuvrability is changing considerably if the vertical and lateral clearance is decreasing. To be able to estimate the hydrodynamic forces occurring in shallow and confined water Flanders Hydraulics Research, a laboratory of the Flemish Government, has invested in several experimental research programs with especially ship models of merchant vessels. The parametric investigation of hydrodynamic effects through experimental fluid dynamics is illustrated for ship manoeuvrability in shallow water, ship-bank interaction, ship-to-ship interaction and the concept of nautical bottom. These effects are applied in a support tool (Protoel) for the evaluation of the admittance policy to the Flemish harbours and are being translated to the even more challenging behaviour of inland vessels. |
