The foundations to 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 is the son of Skipper and shipowner 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.
During the 1990s the company expanded, including in offshore drilling.
By founding Stena Adactum at the beginning of the 2000s the Sphere was expanded to also include long-term investments in outlying business areas. Long Term Equity was founded in 2006 for long-term investments without ownership responsibility.
A considerable number of the investments have focused on companies in the energy sector, including oil and offshore but also in alternative energy sources.
At the beginning of the 2000s expansion also continued in offshore/drilling. Investments in the three oil drillships Stena DrillMax I, II and III, have been the Group’s biggest up until now.
