The foundations for today’s Stena Group were laid on 18 November 1939 when the Sten A Olsson Metallprodukter trading company was founded. In the following years the company expanded both inside and outside the country’s borders.

Sten A Olsson

Sten A Olsson is the son of Skipper and ship owner Gustav Olsson from Donsö. In 1946 he bought his first vessel and the shipping business started on a small scale. At the beginning of the 1960s a ferry service started between Göteborg and Skagen (Denmark).

Over the years freight services using the company’s vessels became a significant part of the business. In 1972 the business was divided into two branches: Stena Line AB and Stena Metall AB. In the same year the Masthugg terminal in Göteborg was completed.

The business continued to expand and at the end of the 1970s major investments were made in offshore and RoRo vessels. Stena Fastigheter (Property) was founded in 1980. The tanker shipping company Stena Bulk was founded in 1982. Northern Marine Management, a management company for vessels that are not Swedish-flagged, was founded in 1983. Concordia Maritime was founded and listed on the stock market in 1984.
