Fuel savings on ships up to 15% with the Air vacity system

This is not a new innovation. Wartsila intoduced this system in late 60's intended for arctic use. Its alos used to reduce propeller inpulses

This is the better design in this yet new art, where many inventors had not been able to resolve the actual problems in real performance on open seas, like leaking air and turning capabilities as well as extra costs of powering the additional system

[JYTILLIER]

How much does running the air compressor costs? does it cost less than the 15% of the saving?

In a flat sea it seems ok? what about with large waves?

Are there any reduction of the life term of the hull due to cavitation type erosion?
