Beschrijving:Organised by Flanders Hydraulics Research and Ghent University - Maritime Technology Division and in association with the Royal Institution of Naval Architects the International Conference on Ship Manoeuvring in Shallow and Confined Water: Bank Effects will offer researchers and pilots the possibility to discuss the latest developments in research and practice related to the ship behaviour in the vicinity of banks.
During the last decades a continuous increase of the main dimensions of certain ship types can be observed; this is especially the case for container carriers, RoRo vessels and LNG carriers. On the other hand, the dimensions of access channels, rivers, canals and ports frequented by these vessels often do not increase at the same rate. As a result, the behaviour of ships arriving at or departing from harbours will increasingly be influenced by waterways restrictions.
The asymmetric flow around a ship induced by the vicinity of banks causes pressure differences between port and starboard sides. As a result, a lateral force will act on the ship, mostly directed towards the closest bank, as well as a yawing moment pushing her bow towards the centre of the waterway.
This phenomenon, known as bank effect, depends on many parameters, such as bank shape, water depth, ship-bank distance, ship properties, ship speed and propeller action. A reliable prediction of bank effects is important to determine the limiting conditions in which a ship can safely navigate a waterway. However, the knowledge of the bank effects induced by the typical bank geometries is very limited. |
