The story
Wallenius Lines was founded in 1934 by Olof Wallenius.
In the 1960s, Wallenius pioneered the roll-on/roll-off concept, first on the North Atlantic trade and later on the Asian trade when Wallenius became the first independent shipping line to work with Japan’s automobile manufacturing industry.
In 2018, Wallenius Lines and Swedish Orient Line established Wallenius SOL to transport forestry products and other goods in the Gulf of Bothnia, Baltic Sea and North Sea, each owning 50%. In April 2026 Wallenius took full ownership.
