UK-based Silverstream Technologies has completed trials of its air lubrication system, Silverstream System, on a Shell-chartered 170,000m³ liquefied natural gas (LNG) carrier, named Methane Patricia Camila.
The system is claimed to have shown approximately 6.6% net savings after its operational testing.
To analyse the fuel and emissions savings, the technology was tested at several vessel speeds at the time of the Methane Patricia Camila’s normal operations.
The unique design of this new system is claimed to increase fuel and emissions efficiency.
The Silverstream System produces a thin layer of micro-bubbles along the entire flat bottom of the vessel, thereby reducing the frictional resistance between water and hull.
During its October 2020 dry docking at the Sembcorp Marine Admiralty Shipyard in Singapore, the system was retrofitted on the 2010-built LNG carrier.
Silverstream Technologies founder and CEO Noah Silberschmidt said: “It is great to announce that retrofitting the Silverstream System onboard the Methane Patricia Camila has already had a significant positive impact on fuel consumption and emissions, with 6.6% savings verified during initial testing.
“Shipping requires solutions to solve the decarbonisation challenge today. With fuel bills only set to rise in the future, owners need to invest in fuel-agnostic technologies that are proven to save costs and emissions, without impacting the flexibility or profitability of the vessel. We are proud of the role that our technology can play to solve this challenge.”
The American Bureau of Shipping (ABS) reviewed and approved the Silverstream System as per its guidance note for air lubrication technology.
Last month, Silverstream Technologies finished trials of the Silverstream System on Grimaldi Group’s newbuild Ro-Ro vessel, named Eco Valencia.
