WATCH: Norwegian Epic Refit and Maintenance
I just stumbled across this video, but it was made back in 2015 when the Norwegian Epic underwent a pretty extensive dry dock. It shows the replacement of the diesel generators, and a lot of other cool things! Check it out:
This was three years ago, and the Epic isn't scheduled for another dry dock until 2020. I don't know that she can continue to satisfy passengers until then, based on what I observed on our recent cruise. We'll see.
