In 2021 she was sold to Creta Cargo Lines, Greece, renamed Orion, and towed to Perama for conversion to increase freight capacity.

[2] Together with her sister ships, Saturn formed a new generation of car ferries built in the 1970s to serve the routes on the Firth of Clyde.

These ships were nicknamed the "Streakers" because of their greater speed (compared to what had served the area's routes previously) and superb manoeuvrability (due to their novel propulsion units).

With Bute's introduction, Saturn moved down the firth to Ardrossan, assisting Caledonian Isles on the Brodick crossing during summer,[6] and acting as a spare vessel during the winter.

Sister ship of Bute, MV Argyle entered service the following month which allowed Saturn to return to her summer duties at Arran.

In October 2010, Saturn took over the Dunoon sailings from older sister Jupiter, which was laid up at Rosneath as spare vessel for that winter, although she never saw service again, and on 25 June 2011 she was towed away to be broken up in Denmark.

She was back on the Bute run on 20 August 2011 to provide extra sailings for the Bute Highland Games [citation needed], subsequently returning to Gourock on 27 August 2011 to help out the Argyll Ferries passenger ferries on the busiest weekend of the year for the Cowal Gathering (Highland Games) in Dunoon.

In response to the ships ongoing deterioration whilst laid up at Rosneath, a small grass roots campaign was launched by those interested and passionate in the fate of MV Saturn.

The ship returned to dry dock under her own power on 23 March 2015, and over the following weeks the full Pentland Ferries livery was applied and steel work was carried out.

[16] Orcadia left James Watt Dock on 22 April 2015 and headed north, leaving her home waters of the Firth of Clyde.

On 16 December 2016 Orcadia was moved back to Pentland Ferries' home port of St. Margaret's Hope for further work and inspection.

[18][19] In 2021, Orcadia was sold to Creta Cargo Lines to provide a Passenger and Vehicle service between Mainland Greece and the Aegean Islands.

[20][21] By 14 July 2022, she had been renamed Orion,[22] and extensive conversion work was being carried out by Spanopoulos Shipyards to increase the ship's freight capacity.
