Allure of the Seas, an Oasis-class cruise ship owned and operated by the company, is the first cruise ship to be housed at the new terminal.
Built with an investment of $125m, the new 161,334ft² terminal is expected to accommodate more than 630,000 vacationers a year.
The terminal is claimed to be the world’s first LEED Zero Energy facility, meeting its energy requirements through the use of onsite solar panels.
To support the Destination Net Zero decarbonisation strategy, the design strategies at the terminal are in line with the environmental objectives of its Royal Caribbean Group parent company.
The new terminal is anticipated to create 800 new jobs as well as generate $1.4bn in local business services revenue.
Royal Caribbean International president and CEO Michael Bayley said: “Now our unmatched Oasis Class ships, known as the best family vacations in the industry, can set sail from Galveston.
“Allure of the Seas is just the beginning, and we thank the Port of Galveston, Ceres, and all the teams involved for making this bold vision a reality.”
Allure of the Seas includes several features, such as an open-air central park with multiple real plants and an aqua theatre entertainment venue.
It also benefits from more than 30 restaurants, bars and lounges, as well as a nine-story-high zip line and two FlowRider surf simulators.
