Leading clean technology company Silverstream Technologies announced that its pioneering air lubrication system, the Silverstream System, has demonstrated significant fuel and emissions savings during testing on Grimaldi Group’s newbuild ro-ro vessel Eco Valencia.Savings figures of 5.1% have been measured during initial performance testing, which has taken place continuously since the Eco Valencia entered service in the Mediterranean. During this process, the Silverstream® System was comprehensively tested at various vessel speeds and in a range of sea states, to calculate and prove fuel and emissions savings.

The technology, which produces a thin layer of micro-bubbles over the flat bottom of the hull, is an integral part of the new vessel’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.

Eco Valencia is the first of 9 Grimaldi Green 5th Generation (GG5G) designs to be installed with the technology. Four vessels with the System onboard have already been built at China Merchants Group Limited’s Jinling Shipyard: Eco Valencia, Eco Barcelona, Eco Livorno and Eco Savona.

The GG5G ro-ro carriers are some of the most advanced ship designs currently on the market. The hybrid propulsion system helps them produce zero emissions in port, and the addition of clean technologies, like the Silverstream® System, further positions them as the eco-ships of the future.

As well as the 9 vessels contracted to be built for Grimaldi Group with the Silverstream® System installed, Silverstream is also installing Systems on Grimaldi Group subsidiary Finnlines’ 3 newbuild GG5G ro-ro vessels and 2 newly ordered ro-pax vessels.
