Recently, China's first energy-saving inland container ship that meets the requirements of EEDI phase III, which is designed by CSSRC Shanghai branch, conducted sea trials for the first time. Its speed in sea trials exceeded expectancy, and was successfully delivered to the owner. Up until now, this ship has completed verifications of first two phases of EEDI. The ship’s EEDI is far below the baseline index, showing excellent results in terms of economy and environment concerns.

At present, adhering to the national strategy of building a conservation-minded society and sustainable development of economy and society, inland water transportation has emerged as one of the most economical and environment-friendly ways of transportation facing brand new opportunities.

 The ship conducted overall design concerning main dimensions, main engine, ship hull optimization, structural lightweight and so on. The design indexes are excellent with competitive performance. The integrated optimal design of ship hull, propeller, rudder and hydrodynamic energy saving device is realized. The vertical bow and symmetrical double caudal fin are adopted, and the low resistance hull design and CFD optimization are carried out. Equipped with high efficiency propeller and tip vortex fin which serves as ESD, the ship has showed good energy-saving performance. A fishtail rudder is designed based on the stern contour, improving maneuverability in narrow and shallow water channels. The general arrangement of the ship is optimized, and the cargo space is expanded with FEM. The container space utilization is improved by adapting the cargo and deck area properly.

The ship’s successful development and good economic benefits will set solid foundations for bringing in design orders of more large-scaled green inland ships, and to expand our market share. For now, the ship is applying for independent intellectual property rights; meanwhile it is vigorously promoted in various ship exhibitions as a demonstration ship.
