British wind power to drive Maersk container ship

Shipping giant Maersk is testing a modern rotor sail from British firm Anemoi Marine Technologies in an effort to cut fuel consumption and greenhouse gas emissions. Anemoi says Maersk will fit one of its rotor sail systems to an 8,700 TEU Lima-class container ship. TEU, or twenty-foot equivalent unit, is the standard measure of container-carrying capacity. That makes the Lima-class vessels relative tiddlers in the container-shipping world. Rival MSC's Irina-class ships measure 400 m (1,312 feet)
