This is interesting - so there's a viking-themed splash battle ride at Plopsaland De Panne in Belgium, there's another viking-themed splash battle ride at Energylandia in Poland, there was a concept for a How to Train Your Dragon viking-themed splash battle ride at Beto Carrero World in Brazil that never got built (https://www.kbxd.info/works/hot-to-train-your-dragon) and one of the designers for that is according to LinkedIn now working at Universal, and then there's the potential of another How to Train Your Dragon viking-themed splash battle ride at Universal's Epic Universe. I suppose it's possible that the first piece of concept art could be for Beto Carrero World (http://www.irms.com.sg/portfolio/all/beto-carrero-world-dreamworks-animation/) but the concept art also shows what looks to be a Sky Fly by Gerstlauer which is not seen anywhere for Beto Carrero World (but it could have still been considered) but it is rumored to be at Universal's Epic Universe.
