Grimaldi Group’s newbuild ro-ro vessel Eco Valencia has achieved fuel savings of 5.1 per cent during a trial of Silverstream Technologies’ air lubrication system.
The vessel has been trialling Silverstream’s system in the Mediterranean with comprehensive testing at various vessel speeds and across 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’s Jinling Shipyard: Eco Valencia, Eco Barcelona, Eco Livorno and Eco Savona.
Alberto Portolano, project manager of air lubrication design and integration, Grimaldi Group, said: “The successful trial of the Silverstream System and the CO2 reduction that it generates is an important step in Grimaldi Group’s aim to lead on shipping sustainability. The trials conducted with the ship in fully loaded service showed the air bubbles covering the entire hull bottom. We are looking forward to continuing to work closely with Silverstream to benefit from their technology on more of our market-leading ro-ro vessels.”
Noah Silberschmidt, CEO, Silverstream Technologies, said: “We are delighted to have reached this latest milestone in our continued partnership with Grimaldi Group. The recorded savings figure of 5.1 per cent exceeded initial predictions and shows that Grimaldi’s vision to install our air lubrication technology as a fuel and emissions reduction solution has paid off.
“We would like to thank Grimaldi for their continued confidence in the Silverstream System. We are proud that our technology plays a central role in these pioneering environmentally friendly ship designs. We look forward to testing further Systems on the GG5G fleet, starting with Eco Barcelona, in the coming weeks.”
“We are particularly pleased to have been able to complete this trial despite the obvious challenges to international travel and supply chains posed by the COVID-19 pandemic. This is testament to the commitment and skills of our team at Silverstream and the strength of our partners, all of which have been vital to ensuring we can continue to support shipowners with their sustainability ambitions.
“All of this takes place against the backdrop of impending vessel efficiency requirements, such as the IMO’s proposed Energy Efficiency Existing Ship Index (EEXI), which further amplifies the central role that clean technologies must have within shipping’s decarbonisation pathway. We are proud to support progressive owners and operators like Grimaldi in future-proofing themselves against new requirements.”.
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.
