The ship is going to end down to the mediteranien. Here name is "Nao Storm" she is an offshore vessel with capacity to take up to 200 persons on board. As Norwegian military expert says, it would be wrong to send an frigate or an coast guard vessel down, since they don't have the capacity needet to handle a large amount of people, in situation like these. An vessel like those in service for Hurtigruten (Costal Steamers) would fit this task perfect. since several of them are designed as an redy as "Hospital/emergency" ship from before.
