Torstein Hagen’s Viking Cruises has firmed up an order for six expedition cruise ships at Fincantieri in Italy.

The US-based operator agreed a potential deal for the 47,800-gt vessels in 2018.

The first two contracts were put into effect in 2019.

Fincantieri has now said the owner has also finalised orders for ships three and four, while signing contracts for the final two, subject to financing.
