Torstein Hagen's Viking Ocean Cruises has signed up for two more cruiseships at Fincantieri in Italy.
The deal brings the number of 47,800-gt vessels being built or completed at the yard to 10.
"Following the agreement signed last April between Fincantieri and Viking Ocean Cruises, the contracts for the construction of the seventh and eighth ships have become effective and, furthermore, the company has exercised the option for the ninth and tenth," Fincantieri said in a statement cited by Cruise Critic.
Four are already operational, with the final two due for delivery in 2022 and 2023.
The fifth and sixth ships were added last November 2016.
The ships have 465 cabins and can accommodate 930 passengers.
They are designed by Fincantieri and the initial order was priced at EUR 300m ($322m) per vessel.
