Automatic Ship Berthing Motion Identification Neural Networks Control
2009/5/12
In this paper, motion identification using ANN and its application to automatic ship berthing will be discussed. Motion identification method is adopted to estimate the effect of disturbances and then...
A Study on Bow-Diving for Planing Craft-Criteria of Bow-Diving Occurring
High-Speed Planing Craft Longitudinal Motion Bow-Diving Hydrodynamics
2009/5/12
The purpose of this paper is to clarify the cause of occurrence of Bow-Diving for planing craft. First, measurements of Bow-Diving using a scale model of planing craft are carried out and they confirm...
A Study of On-Board Monitoring and Analysis System of Ship Propulsion Performance-An Estimation Method of Propeller Performance with Surface Roughness Effects
Propeller Performance Surface Roughness Ship Propulsion Performance Monitoring
2009/5/12
The propulsion performance of actual ship at sea tends to deteriorate mainly due to the fouling of hull and propeller. It is important, therefore, to monitor the present situation of ship propulsion p...
Experimental Study on Scale Effect of Drag Reduction by Microbubbles Using Very Large Flat Plate Ships
Microbubbles Scale Effect Frictional Drag Reduction Very Large Plate Ship
2009/5/12
Using flat plate ships of up to 50m in length in a 400m-long towing tank, we carried out experiments on the scale effect of microbubbles, the aim being to apply microbubbles to full-scale ships. The s...
