The effective acquisition and statistics of the energy efficiency data of operational ships are of great importance to accurately know the energy efficiency level and emission of the ship for the Ship Management Administration. It is also needed for making the policy of energy saving and emission reduction. The energy efficiency data acquisition and management software is developed based on the above...
The accurate measurement of real-time vessel fuel consumption is very important for accurate calculation of ship energy efficiency as well as for ship management department to get vessel fuel consumption. A kind of real-time vessel fuel consumption monitoring system was designed to obtain real-time information of oil consumption of main engine and auxiliary engine, main engine speed, main engine axle...
Now Canal ship use internal combustion engine as power source which rely on nonrenewable resource and cause air pollution, noise pollution, oil spill pollution. In order to solve the problem, a new type of Canal ship based on overhead wires is designed. Through learning from the operating and construction principle of trolleybus, the overhead wires are set up over the Canal which supply power for...
It is of great significance for the research of wind load in energy saving and emission reduction as wind load is one part of the ship total loads. An inland cruise ship is chosen as a research object, the wind loads on the ship including longitudinal and transverse forces and the yaw moment are calculated in wind angle of 0–180° by using CFD method, and then the numerical result is compared with...
According to the navigation characteristics of the inland ship, a multiple-constrained model of minimum fuel consumption is established. Some information collection sensors are amounted on this ship in order to obtain the research data. Through analysis and process of these data, the regression functions between main engine fuel consumption and shaft revolution speed and between ship speed to water...
In case of ship oil spill accidents, the oil will spread quickly if it is not detected and monitored in time. The later the oil is detected, the more harmful it will be and the more difficult to identify the accident ship. A real-time oil spill monitoring system for inland waterway is designed, which is based on navigation marks with the transponders of marine automatic identification system, and...
