Development of the hull-form of catamaran by using CFD and experiment
the hull-form of catamaran CFD experiment numerical simulation
2009/4/29
Wake wash is one of the serious problems for high speed ships, because it may cause damage on the coastal aquaculture using rafts or nets. Since some important parts of high speed ships are catamaran,...
Development of a Weather Adaptive Navigation System- Influence of Weather Forecast
Weather Adaptive Navigation System Weather Forecast simulations
2009/4/29
We propose a new navigation system to decrease fuel oil consumption and CO2 emission from ship. To decrease them it is important to avoid rough seas and to reduce the speed of ship. Therefore the syst...
