Grimaldi newbuilds to feature Silverstream air lubrication technology

Italian shipowner Grimaldi Group has chosen Silverstream Technologies’ air lubrication system for installation to 12 hybrid RoRo vessels to be built over the next three years. Silverstream’s technology produces a thin layer of bubbles beneath the surface of the vessel, reducing the resistance between the vessel’s hull and the water. This improves operational efficiency by...
