Large energy-saving green river container ship

Abstract

The invention provides a large energy-saving green river container ship which comprises a ship body. The large energy-saving green river container ship is characterized in that the head line of the ship body is in a straight bow shape, the tail line is in a twin skeg shape, a main deck is arranged on the upper surface of the ship body, and a first void compartment and fore peak, an auxiliary machinery room, a cargo hold, an engine room, a fuel oil tank and a tail ballast tank are sequentially arranged under the main deck from the ship head to the ship tail; the fuel oil tank is arranged in the middle of the tail ballast tank, the steering engine room is arranged at the tail of the main deck, the cargo hold extends towards the head from the front wall of the engine room to the back wall of the auxiliary machinery room, a pipe tunnel is formed in the portion under the cargo hold, and energy saving devices are additionally installed on propellers adopted by the ship body. According to the large energy-saving green river container ship, overall arrangement is optimized, the area of the cargo hold and the deck is utilized to the maximum limit, the loading rate is maximized, and the loading quantity is larger than 500 TEU.

Description

technical field [0001] The invention relates to the technical field of large transport ships, in particular to an inland river large energy-saving green container ship. Background technique [0002] With the development of the economy and the country's advocacy of green ships, it is necessary for the ship type to develop in the direction of energy saving, green, environmental protection and economy. [0003] The current defects of inland river container ships are: (1) The utilization rate of container loading is low, and the economic performance needs to be improved. (2) The line shape design of the hull has not been fully optimized, coupled with the large wind area, the resistance encountered during navigation is relatively large, and the energy consumption is relatively large. (3) Energy-saving devices are not popularized, and the propulsion efficiency is low, so it is difficult to meet the current requirements of energy-saving and emission-reducing green ships. (4) Due ...

AI Technical Summary

Problems solved by technology

[0003] At present, the defects of inland river container ships are: (1) The utilization rate of container loading is low, and the economic performance needs to be improved

(2) The line design of the hull has not been fully optimized, coupled with the large wind area, the resistance encountered during navigation is relatively large, and the energy consumption is relatively large

(3) Energy-saving devices are not popularized, and the propulsion efficiency is low, so it is difficult to meet the current requirements of energy-saving and emission-reducing green ships

(4) Due to the narrow channel of the Yangtze River, the maneuverability of the ship needs to be further strengthened

Compared with non-LNG energy ships, the storage of LNG needs to add an additional independent special compartment, which will compress the space of the cargo hold, which is not conducive to the improvement of the utilization rate of the container space

The steering engine room is also arranged below the main deck, which will also compress the space of the cargo hold, which is not conducive to the improvement of the utilization rate of the container space

It has not yet met the requirements of the green ship-III ship energy efficiency design index and the second stage of the fuel consumption index, and the environmental protection performance needs to be strengthened
