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...
Effects of sway motion on roll reduction performance of an Anti-Rolling Tank
sway motion roll reduction performance Anti-Rolling Tank
2009/4/30
Effects of sway motion on roll reduction performance of a U-tube-type anti-rolling tank are experimentally investigated. Forced rolling and swaying tests of an anti-rolling tank model show that the w...
Improvement of Water Entry Performance of a Free-fall Lifeboat
Water Entry Performance Free-fall Lifeboat situations
