Havent worked in an ROV capacity but in my limited experience SS7 vessels are pretty good, the Viking is a cracking ship, one of the nicest I’ve seen, I was on board doing a Radascan installation over the course of a week along with a particularly traumatised Kongsberg engineer trying to do a DP s/w upgrade that just refused to go smoothly or work properly, say hi to Bruce Cowie if youre on at same time as him, former colleague. As it happens the radascan wasnt right when it left the factory (as usual) and post install it wasnt up to scratch either. The survey guys there were a huge help at the time and it seemed a good vessel to be on board.
Was briefly on one of the Rocky’s and had a particularly odd slice of beef curry pizza one night :S
