US giant Royal Caribbean Cruises (RCCL) has ordered another in its Edge series of cruiseships in France.
It said it had entered into an agreement with the Chantiers de l'Atlantique yard to build a fifth vessel for delivery in the autumn of 2024.
The first in the series for its Celebrity Cruises brand, the 130,000-gt Celebrity Edge, was delivered in 2018.
Three more of 117,000 gt are due in 2020, 2021 and 2022.
The new order is contingent upon financing, but no price was revealed.
"Edge class made an immediate hit with Celebrity Cruises guests and is a state-of-the-art example of technical excellence and elegant design," said Richard Fain, RCCL CEO.
"We can't wait to build the next one."
"We are really proud and happy to have built such an outstanding relationship with our customer, based on mutual trust and driven by the spirit of innovation," said Laurent Castaing, general manager of Chantiers de l'Atlantique.
"After the four Millennium-class ships at the beginning of the 2000s and the four Edge-class ships, this is the ninth ship ordered by Celebrity Cruises at our shipyard and it will be the 24th vessel built by Chantiers de l'Atlantique and operated by RCCL. This is a real testimony of the exceptional level of cooperation we reached together."
