Clean technology company, Silverstream Technologies’ air lubrication system, the patented Silverstream System, has delivered significant fuel and emissions savings during tests on the Shell-chartered 170,000 cu m LNGC ‘Methane Patricia Camila’.
Following the testing of the retrofit, Silverstream and Shell’s engineers claimed that a 6.6% net saving was generated by the system.
The air lubrication system was tested at various vessel speeds during the LNGC’s normal operations to calculate fuel and emissions savings.
The Silverstream System produces a thin layer of microbubbles along a vessel’s full flat bottom, reducing frictional resistance between the water and the hull.
It was retrofitted on the 2010-built LNGC during her October 2020 planned drydocking at the Sembcorp Marine Admiralty Shipyard in Singapore.
The project was installed within the planned drydocking period, and was delivered on budget, Silverstream said.
From design through to installation, the technology was reviewed and approved by ABS in accordance with the class society’s guidance note for air lubrication technology.
Noah Silberschmidt, Founder & CEO, Silverstream Technologies, said: “It is great to announce that retrofitting the Silverstream System on board the ‘Methane Patricia Camila’- has already had a significant positive impact on fuel consumption and emissions, with 6.6% savings verified during initial testing. We’d like to thank our colleagues and partners at Shell for their confidence in our technology, and also for their vision and commitment to pioneer proven clean technologies within shipping.
“Shipping requires solutions to solve the de-carbonisation 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,” he said.
