To improve their financial position Tor line sought out partnerships with other shipping companies. In 1979 (the former "Tor Anglia") was chartered for a planned joint Gothenburg—Kristiansand—Newcastle with Fred. Olsen, but Fred. Olsen pulled out before the service could commence. Instead the "Espresso Olbia" was laid up in Gothenburg. In early 1980 a more successful joint service was formed with Sessan Line, when Sessan Tor Line was established. Logos of the new joint service were painted on Tor Line's ships. Sessan Tor Line proved short-lived as Sessan's main competitors Stena Line purchased Sessan in early 1981. Subsequently, Tor Line entered negotiations to sell either the "Tor Britannia" or "Tor Scandinavia" to DFDS. Instead of buying just one ship DFDS purchased the entire Tor Line passenger division in late 1981. Initially the Tor ships were marketed as DFDS Tor Line, but were subsequently absorbed into DFDS' passenger division DFDS Seaways. Despite this they kept their original Tor-prefixed names until 1990–1991.
