Europe-based lines Celestyal Cruises and Fred. Olsen Cruise Lines both said they had purchased ships from Carnival Corp., which has said will shed 13 ships from its nine brands this year.

Greece-based Celestyal said it had acquired the 1993-built, 1,800-passenger Costa NeoRomantica from Costa Cruises, while Fred. Olsen said it had purchased the youngest pair of the four ships leaving Holland America Line’s fleet.

The U.K.-based Fred. Olsen said it had acquired the Amsterdam, built-in 2000, and the Rotterdam, built-in 1997 and would rename them the Bolette and Borealis, respectively, both names of former Fred. Olsen ships.

“We have chosen these vessels as they will fit seamlessly into our existing fleet of small ships, each carrying under 1,500 guests, bringing with them new and larger public areas whilst not compromising on our small-ship experience,” said Fred. Olsen Jr., chairman of Fred. Olsen Cruise Lines, in a statement. “This increase in our capacity demonstrates our confidence in the future. With over 170 years of seafaring history, we have sailed through many difficult periods. With these new additions to the fleet, we will come out of this current situation stronger than ever, ready to deliver the award-winning itineraries that we are famous for.”

Celestyal’s CEO, Chris Theophilides said that the NeoRomantica purchase is part of the line’s strategic growth plan, despite being on pause until 2021.

“I’m delighted with the addition of this midsize cruise vessel to our fleet,” Theophilides said in a statement. “She is ideally suited to our business model and is very well appointed following her significant transformation in 2012.”

Details of the ship’s delivery and deployment will be announced at a later date, Celestyal said. It is the second Costa ship to exit its fleet since Carnival Corp.’s announcement about shedding ships. The 23-year-old Costa Victoria was sold for scrap.
