(10:48 a.m. EDT) -- Carnival Cruise Line's second Excel-class cruise ship will sail from Miami in 2022. The currently unnamed ship will be a sister vessel to Mardi Gras, which launches next year.

The announcement came after Miami approved the line's plans to expand Terminal F at PortMiami to accommodate bigger ships.

"With today's approval, we will move quickly on a plan to remodel and expand Terminal F so that it will accommodate the most innovative class of ship to join our fleet," said Christine Duffy, president of Carnival Cruise Line.

Mardi Gras, the first Carnival Cruise Line ship in many years to not include "Carnival" in its official name, will homeport in Port Canaveral after inaugural sailings in Europe and New York.

Highlights of the ship include six themed "zones" with a variety of dining and entertainment options, including a new Creole restaurant developed by Celebrity Chef Emeril Lagasse, as well as the first-ever roller coaster at sea. The ship also will boast a classic blue hull design, with red and white accent stripes that will run the entire length of the ship.

Work on Terminal F is scheduled to be completed by October 2022, and the second Excel-class ship is due to arrive in late 2022.
