All good stuff, but one thing you probably should be aware of!
Many of the large tankers have nets strung across the landing sites, this goes for Rigs as well. Initially seems a good idea for deck grip on a painted surface, however in some cases there is a darker side.(From the point of the aircrew) I have seen where, on oil tankers, the net is connected to a winch which is used to remove the burning wreckage of your helicopter as fast as possible off of the deck of a large floating bomb!
Just for info!
Have fun
