The company was spun off from Wallenius Lines in 2003 to focus on ship management and technical services, as well as newbuilding and design.

[5] The ships are built in third-party shipyards in Japan, South Korea and China[2] with site supervision by Wallenius Marine.

Other business areas include ship elongation, where existing cargo vessels are stretched to extend their capacity.

The process typically takes a few months compared to a few years for designing and building a new ship from scratch.

[9][10] In addition to reducing the environmental impact of traditional cargo ships, the company is developing a wind-powered car carrier called Oceanbird.
