Modelling navigation in muddy areas through captive model tests
- 148 Downloads
Many access channels and harbours suffer from sedimentation and formation of mud layers. To keep navigation safe and economic, extensive maintenance dredging is needed. Until now, the required level of dredging has always been determined by making use of the physical characteristics of the mud layer, which does not necessarily result in efficient dredging. Ship behaviour also matters, and knowledge of ship manoeuvrability can help to redefine the level of dredging required. A mathematical model of manoeuvring for simulation purposes, based on a comprehensive series of captive model tests, is presented, along with a selection of results.
