The 530-guest expedition ship, which uses battery power, is due to be delivered ahead of schedule allowing Hurtigruten to add a series of extra sailings before its 1 April maiden voyage.

Departing from London (7 March), Liverpool (12 March) and Portsmouth (17 March), the five-night voyages will take guests to explore destinations in and around the British Isles – visiting locations such as the Isles of Scilly, Fowey, Isle of Man and Dartmouth.

A four-night voyage to Oslo will also take guests through the Kiel Canal and Aalborg in Denmark.

Nansen has undergone sea trials off the west coast of Norway this week.

Hurtigruten launched the world’s first hybrid-powered cruise ship, Roald Amundsen this year.

Chief executive Daniel Skjeldam said: “We see great demand for our expedition cruises across all markets and all destinations.

“With their green technology and unprecedented focus on sustainable solutions, Fridtjof Nansen and Roald Amundsen are not only driving demand, they are driving change in the cruise industry.”
