During the Concept Design phase of Shanghai Haichang Ocean Park, the park's signature Steel Dolphin coaster was conceived by Legacy Entertainment as an Intamin Aquatrax coaster. It would have only been the second of its kind in the world, following Atlantis Adventure at Lotte World in Seoul, Korea. While the ride type was changed to a multi-launch Blitz Coaster during Schematic Design, key features from the original design, including the tunnel dive and splashdown were maintained.
