After years of speculation, CMAL announced in February 2015 that "Saturn" had been sold to Pentland Ferries to be converted for use as a freighter and for renewable energy work around Orkney and the Pentland Firth. On 25 February "Saturn" was towed from her berth at Rosneath to the Garvel dry dock in Greenock for a major overhaul, sharing the dock with the sail training ship "Stavros S Niarchos". Both ships were un-docked and towed round to the James Watt Dock in early March 2015. The lower part of "Saturn"'s hull had been painted red, and repainting in Pentland Ferries red livery continued, with their logo soon replacing the CalMac logo on the funnel. 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. Dry docking was complete by early April and the ship returned to James Watt Dock. On 10 April 2015 the new name "Orcadia" was painted on the bow and stern of the vessel. "Orcadia" left James Watt Dock on 22 April 2015 and headed north, leaving her home waters of the Firth of Clyde. She arrived at St. Margaret's Hope on the morning of 24 April 2015 and carried out short berthing trials. Further work was carried out following her arrival at Stromness. On 16 December 2016 "Orcadia" was moved back to Pentland Ferries' home port of St. Margaret's Hope for further work and inspection. Since January 2017, "Orcadia" appeared for sale. Since September 2018, "Orcadia" was still awaiting a future. Following a summer of disruption on the Arran crossing, Scotslion Ferries Ltd considered buying her to provide a freight-only service to Arran with 2 ferries. Unfortunately this was later abandoned after they realised the ship was not suitable.
