Abstract
    Inland vessels typically spend most of their operation time in shallow and restricted waterways. For investigating the specific effects of such circumstances on ship hydrodynamics, ship model tests are carried out in the fully automated Towing Tank for Manoeuvres in Shallow Water (cooperation Flanders Hydraulics Research – Ghent University). In 2010, systematic captive model test series were carried out with a 1/25 scale model of a CEMT class Va inland vessel to provide the full bridge inland simulator Lara at Flanders Hydraulics Research with dedicated mathematical models for simulating the manoeuvring behaviour of this type of vessel. In particular, the effect of the presence of banks on ships navigating on a course parallel to these banks has been investigated. Based upon these model tests a mathematical model for the bank induced forces and moments has been developed. The influence on these bank effects is investigated and a mathematical model is implemented in the real time simulators at Flanders Hydraulics Research. The importance of bank effects on inland navigation is illustrated by means of a specific simulation project on the rivers Deûle and Lys in Northern France.The simulations mainly focused on the meeting of two inland vessels and the (hydrodynamic) consequences of the interactions (both ship – ship and ship – bank interactions). A comparison is made between alternative canal cross-sections which also meet the French internal waterways Circular, which led to the conclusion that solutions with a larger water depth are preferable with respect to the magnitude of bank effects.
