So, I have seen one of the videos where you can see the loss of power donnatella, 3 times to be exact....let me go find it. Also, there are emergency generators that automatically come online. So lights and things would not necessarily completely go away. The backup steering is a whole other component and they use sound powered radios for those communications, but that's if someone got down to the emergency steering room in time. Let me find the video.
@Chiza : This particular vessel was an older leased one so some of the safety requirements may not be up to date as the newer ones. Despite guidelines, some of these vessels are still in the global carrier's fleet. We are fortunate that our 23 vessels are for the most part less than 10 years old, with a few exceptions of leased vessels.
