Watch as Giant Sphere Added to Royal Caribbean's Icon of the Seas

Royal Caribbean International's Icon of the Seas remains on track to make its highly anticipated debut next year but recently took a key step with the addition of its 175-metric-ton sphere.

First seen this past December, the impressive feature can be seen coming together in a 50-second video shared on Facebook by Royal Caribbean International President and CEO Michael Bayley on Tuesday.

"Exciting construction update on Icon of the Seas! A top-secret piece of the revolutionary ship is on the move in Turku, Finland," he wrote.

Measuring 46 feet tall and 50 feet in diameter, the sphere required a pair of tugboats capable of producing as much as 2,540 horsepower and a 5,600-metric-ton crane to install.

Royal Caribbean says that a whopping 45,000 working hours have gone into constructing Icon of the Seas' sphere.
