Wide shallow ship energy-saving research passed acceptance

Recently, the Ministry of Transport has established a scientific and technological project "Research on the Application of Practical Technologies for Energy Saving and Emission Reduction of Inland Water-wide Shallow Vessels" through acceptance. The project has systematically studied a large number of shallow and shallow vessels on the Yangtze River and proposed a series of energy-saving and emission-reduction technologies. The improvement of technology will help promote the energy saving and emission reduction of inland shipping.

The project is jointly undertaken by the Institute of Water Transportation Science and Technology, the Yangtze River Institute of Shipping, and Wuhan University of Technology. Due to the restriction of navigational conditions, the large-scale vessels in China are characterized by wide and shallow features. The project proposes the technical route options for energy-saving and emission-reduction of inland water transport vessels in China, and points out the direction for further research on energy-saving and emission-reduction technologies; A wide ship-type line design method for inland rivers has developed a practical and simple ship energy-saving appendage device, which has been verified by experiments to achieve an overall energy-saving effect of more than 5%. It has established relationships with water flow speed, ship speed, main engine power, and fuel consumption. The model of dynamic control of the ship's main engine with a certain amount of parameters was developed. The ship's host dynamic oil control simulation software was developed, and the feasibility of the ship host's dynamic oil control optimization program was verified through simulation tests and real ship tests.
