They're saving 12%, on the best days. The average is 3.8%.

What's not covered in the article is the weight of the devices and the amount of cargo that must be removed from the load to support them. Without that you can't project forward at all.

And even so, you're never going to get to 100%. Cargo ships need electricity to keep cargo refrigerated. They need to be anchored for long periods of time. They need to navigate harbors and other channels.

According to the article it is 12 tons/day on the best days and 3.3 ton/day average. 14% average with 37% max for reduction of greenhouse gases emissions.

Where are you getting these figures? They aren't the same as the ones in the article.
