Carnival Corporation today announced that it had signed a memorandum of agreement with Fincantieri to build two new cruise ships for Holland America and Princess.

With the new agreement, Carnival Corporation now has 19 new ships scheduled to be delivered between 2017 and 2022, according to a statement.

Holland America Line’s new ship will be built at Fincantieri’s shipyard in Marghera, Italy, with an expected delivery in 2021, and the ship for Princess Cruises will be built at Fincantieri’s Monfalcone, Italy, shipyard with an expected delivery in 2022.

“We are extremely pleased to formally announce these two new ships and build on the success and popularity of their sister ships already sailing guests around the globe,” said Arnold Donald, CEO of Carnival Corporation. “Our goal is to exceed expectations of the 11.5 million guests who sail with us each year, and these new ships will offer more opportunities for our guests to create lifelong vacation memories while generating added excitement around the fast-growing global demand for cruise vacations.”

Added Donald: “Using our strategic fleet enhancement plan to introduce new ships is an important part of our measured capacity growth strategy, which includes replacing less efficient ships with newer, larger and more efficient vessels.”

Holland America Line’s new 99,500-ton, 2,660-guest ship will be its third “Pinnacle” class vessel, following the design of the line’s newest and largest ship, ms Koningsdam, and its sister ship, Nieuw Statendam, scheduled for delivery in November 2018.

rincess Cruises’ new 145,000-ton ship will carry 3,660 passengers and will be its sixth “Royal” class vessel.

The two yet-to-be-named vessels also under construction by Fincantieri scheduled for delivery in 2019 and 2020.

“This is an extraordinary moment for the cruise sector and it is particularly rewarding for us to be able to seize all the opportunities coming from the industry growth, also thanks to our deep-rooted partnership with Carnival Corporation,” said Giuseppe Bono, CEO of Fincantieri. “These vessels will be based on the successful platforms developed for Carnival. On the back of these successful platforms, our Group today aims to further increase its order book, already at record levels, while ensuring profitability in the cruise segment.”
