Ship all-electric propulsion and the traditional ship propulsion compared to what advantages

Advantages of all-electric propulsion:

One, save space: eliminating the transmission shaft system, reduction gearboxes, while the length of the shaft system often accounted for about 40% of the length of the ship, thus improving the layout of the nacelle structure, saving a lot of space for the drogue system, cabin layout, material reserves, and is conducive to the modularization of building the ship -- this is one of the biggest advantages of all-electric propulsion. One of the biggest advantages of all-electric propulsion.

Two, easy to operate: motor speed is easy to adjust, the distribution of electrical energy automation, electronic. Not only positive and negative rotation can provide constant torque, so the start acceleration is good, fast braking, forward and reverse speed switching fast, and in the high energy-consuming weapons and high-speed drive between the regulation of electricity is convenient, fast, accurate and efficient - this is the biggest advantage of all-electric propulsion two

Three, fuel saving: multi-group motor deployment operation, to ensure that the majority of the time Time system working characteristics are in the best working condition, so than the internal combustion engine propulsion fuel consumption by about 10%, improve transportation efficiency by 15%. And gas turbine, steam turbine, in the low-speed navigation, energy consumption is not less than high-speed navigation when consuming much.

Four, low noise: the generator is installed in the elastic base, running at a constant speed, and the shaft system and the hull also has no direct linkage, so it can greatly reduce vibration and noise

Five, more environmentally friendly: diesel or internal combustion engine work in the best working area, fuel combustion quality, less nitrogen oxide content, reducing emissions.
