When I go around the country, I do staff meetings on ships or on our bases, and what I've heard from staff who work on the Amundsen is that they actually work more than on other icebreakers, because the scientists put them to task a lot. Also, given the number of scientists on board the Amundsen, they are more crowded in their cabins, so we have to put a lot of them two to a cabin. As well, they have to operate very sophisticated equipment that we don't have in any other vessels, so that does require additional training.
I don't know if Claude wants to add something.
