Stena Line

Stena Line is a Swedish shipping line company and one of the world's largest ferry operators. It services Denmark, France, Germany, the United Kingdom, Ireland, Latvia, the Netherlands, Poland, Finland and Sweden. Stena Line is a major unit of Stena AB, itself a part of the Stena Sphere. It is a sister company to Stena Bulk, one of largest tanker companies in the world.

Stena Line was founded in 1962 by Sten A. Olsson in Gothenburg, Sweden, which still serves as the company's headquarters, when he acquired Skagenlinjen between Gothenburg and Frederikshavn, Denmark.

In 1972, Stena Line was one of the first ferry operators in Europe to introduce a computer-based reservation system for the travel business area. In 1978, the freight business area also started operating a computer-based reservation system.

The first freight-focused route started between Gothenburg, Sweden, and Kiel, Germany. The ship was the MS Stena Transporter.

During the 1980s, Stena acquired three other ferry companies.

In 1990, Stena Line doubled in size with the acquisition of Sealink British Ferries from Sea Containers. This first became Sealink Stena Line, then Stena Sealink Line and finally Stena Line (UK), which now operates all of Stena's ferry services between Great Britain and Ireland.^{[citation needed]}

In 1996, Stena Line introduced its 20,000 tonne HSS (High-speed Sea Service) vessels, which operated: Belfast–Stranraer; Holyhead–Dún Laoghaire and Hook of Holland–Harwich. In addition to the three 1,500-passenger HSS vessels, Stena Line ordered two smaller 900-passenger HSS vessels to operate on the Gothenburg–Frederikshavn route. Due to the bankruptcy of the shipyard, only the first of these vessels was ever completed.

In 1998, Stena's operations from Dover and Newhaven formed a joint venture with P&O European Ferries as P&O Stena Line, owned 40% and 60% respectively. In 2002, P&O acquired all of Stena's shares in the company, thus becoming the sole owner of P&O Stena Line, which soon changed its name to P&O Ferries.
