Silverstream Technologies said it has signed a major new deal with Italian shipowner Grimaldi Group SpA to install its proprietary air lubrication technology on board 12 cutting-edge, hybrid Ro-Ro vessels that are being built over the next three years.

The technology, which produces a thin layer of micro-bubbles for the flat bottom of the vessel, will be an integral part of the new design's portfolio of emissions and fuel reduction measures. Air lubrication reduces the frictional resistance between the water and the hull, improving operational and environmental efficiencies.

Silverstream expects that the system, which will last the lifetime of the new vessels, will reduce fuel consumption and associated emissions. Additionally, the Silverstream System has been designed to provide continuous reliable performance and is simple to operate and maintain.

Grimaldi's Green 5th Generation (GG5G) vessel project was conceived over the last year in conjunction with Danish naval architect Knud E Hansen. The vessels will emit zero emissions in port following the installation of lithium batteries, and, in addition to Silverstream's technology, will also be fitted with solar panels and scrubbers to further reduce emissions.

The Grimaldi Group expects the first of the new vessels to be completed in May 2020 and become operational by Q3 2020 on Mediterranean ro-ro trade routes.
