By the early 1970s Tor Line had essentially defeated their main competitors on the route, Rederi AB Svea and Swedish Lloyd.

To consolidate their leading position the company decided to order a pair of new state-of-the-art ferries for the service.

The two ships revolutionized trans-North Sea traffic, being capable of speeds in excess of 27 knots and offering services hitherto unknown on ferries in that route.

Although technically modern in many ways, the ships' exteriors were quite traditional in their style, reminiscent more of ocean liners than ferries.

Nine windows were smashed and the ship started taking in water from the forward air intakes on the superstructure.

The winter passenger numbers weren't the only problem, and Tor Line started looking to form a partnership with another shipping company.

This time her name was temporarily changed to MS World Wide Expo and she sailed extensively in Asia and the Middle East.

In 1981, Tor Scandinavia also starred in the BBC soap opera Triangle, which was shot entirely on board the ship.

For the second and third series the DFDS ship, MS Dana Anglia was used instead due to a greater amount of time in port which made recording easier.

In the same year the ship was moved to Danish International Shipregistry, which meant less operational costs for the company.

In 1989 Scandinavian Seaways decided to start trafficking from Gothenburg to Amsterdam again, so from February 1989 onwards Tor Scandinavia alternated on the routes Gothenburg–Harwich and Gothenburg–Amsterdam.

In September of the same year a fire broke out on board during a crossing to Harwich, and the ship was forced to sail to Esbjerg instead.

In January 2005 she was again rebuilt, this time with a new sprinkler system and catalytic converters, and her cabins and public areas were upgraded.

In September 2010, two tourists were killed in an accident as a vehicle ramp was moved whilst they were driving off the Moby Otta in Genoa.
