WW conducts shipping activities and specialises in roll-on roll off cargo, especially for large project and awkward cargoes like train coaches, small aircraft and large industrial machinery. This is aided by the fact that their Ro-ro vessels have large ramps that can support up to 420 tonnes cargo weight at a time. Together with its partners (EUKOR and Wallenius Lines), the group controls some 160 car and roll-on/roll-off carriers operating in a global network of trades. Its customers include manufacturers of cars as well as construction and agricultural machinery. In the car carrier market, they are the third largest carrier tonnage wise after MOL and NYK Line. On an annual basis, WW's shipping companies transport 5 million cars and 12 million cubic metres of high and heavy and non-containerised cargoes.
