Description
When a ship navigates confined waters, the surrounding bathymetry alters the flow field around its hull and gives rise to strong ship–waterway interaction. This interaction appears mainly as vertical motion (squat), lateral motion (bank effect), and significant long- and short-period waves. Because long-period waves are reflected at inlets and outlets, they can affect following vessels. Since these effects increase sharply with vessel speed and blockage ratio, they are of particular concern in inland waterways and in estuarine channels used by seagoing ships. The planned Stad Ship Tunnel has raised further questions in this regard: although transit speeds will be moderate, the degree of confinement is exceptionally high.
A range of simulation tools is available for predicting ship–waterway interaction, from fast simplified approaches to computationally expensive high-fidelity methods. The present work investigates the capability of REEF3D to predict these interactions, with particular focus on confined waterways.
