At 10 storeys high, Harmony of the Seas’ Ultimate Abyss is not only the tallest slide at sea but also an amazing engineering feat. Get an inside look into the construction process with the manufacturing team as well as the world’s only thrill engineer! Hear what makes Royal Caribbean’s Ultimate Abyss such an epic adventure…
“My name is Denise Key-Tielebein and I am the Project Manager for Harmony of the Seas, Ultimate Abyss. Today we are here at the Wiegand Maelzer facility at Rasdorf, Germany where we are able to see some of the first pieces come off of the production line.”
Denise Key-Tielebein, Project Manager, Newbuilding, Royal Caribbean Cruises, Ltd.
“We’ve been working from the very beginning together with this great team of architects and designers of Royal Caribbean to create this ultimate thrill ride. The Ultimate Abyss is going to be the tallest slide at sea, over 28-meter heights and a total length of 72 meters each.”
Amelie Suldinger, Sales Manager, Wiegand Maelzer
“I am Professor Brendan Walker, I’m the world’s only thrill engineer. Some people know me as “Professor Thrill.” I’m going to be keeping an eye on the manufacturing process of Ultimate Abyss and finally when it’s installed, I’m going to get to go down it first. It’s quite nice for me.”
Brendan Walker, “Professor Thrill”
“We are really under pressure to get all these different kinds of construction, installation, manufacturing, all together to be in time. The manufacturing will be stainless steel slides and the steel construction itself will be manufactured here.”
Markus Rudolph, Project Manager, Wiegand Maelzer
“The greatest challenge is of the Ultimate Abyss was to take into consideration the vibrations on the ship, the loads, the forces, and at the same time, making a great design feature for Harmony of the Seas.”
Amelie Suldinger, Sales Manager, Wiegand Maelzer
“When you look at the CAD drawings, you see the snaking structure going through the ship’s architecture, you think okay, it’s just a slide. When you see these sections here, you really get sense of scale. To get that, and multiply it by all those sections you see, it’s a massive slide I mean I’ve never seen anything like it.”
Brendan Walker, “Professor Thrill”
“When you live a project for so long, the moment you see that first piece, you just can’t describe it.
Between the design phase and now the fabrication phase we are soon going to be installing the slide on Harmony of the Seas.”
