Grimaldi Group’s newbuild ro-ro vessel saved 5.1% in fuel consumption
According to performance testing results, the use of Silverstream's air lubrication system reduced fuel consumption and emissions by 5.1 percent on Grimaldi Group's newbuild ro-ro vessel Eco Valencia.
In October 2020, Grimaldi received the first of twelve 5th Generation (GG5G) class hybrid RoRo ships, Eco Valencia.
The ship has been in service on the regular line between the Italian ports of Livorno and Savona and the Spanish ports of Barcelona and Valencia since mid-November.
Since Eco Valencia entered service in the Mediterranean, it has been subjected to comprehensive testing.
“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,” Silverstream announced.
The technology creates a thin layer of micro-bubbles on the hull's flat bottom, reducing friction between the water and the hull and thus improving operational and environmental performance.
The air bubbles filled the entire hull bottom during the trials, which were performed with the ship fully loaded.
The device has already been mounted on four ships constructed by China Merchants Group Limited's Jinling Shipyard: the Eco Valencia, Eco Barcelona, Eco Livorno, and Eco Savona.
Silverstream is also installing air bubble systems on three newbuild GG5G ro-ro vessels and two newly ordered ro-pax vessels operated by Grimaldi Group subsidiary Finnlines.
