The line’s Welcome Back programme will feature 11 cruises departing Dover and Liverpool this summer.
Sailings will take in the best of the British Isles, including Shetland and Orkney, and the Isles of Scilly.
New ship Borealis will be the first to set sail offering a three-night maiden voyage from Liverpool departing 5 July.
The line’s other new ship, Bolette, will depart on its maiden voyage from Dover on 16 August.
"So often overlooked, our British Isles are home to some of the most wonderful wildlife, and so much spectacular scenery that is best enjoyed from the water," said Fred Olsen managing director Pete Deer.
