Silverstream Technologies agrees to retrofit Shell LNG carriers
Published by Will Owen,
UK-based Silverstream Technologies has signed a framework agreement to retrofit an unspecified number of LNG carriers in the Shell fleet with air lubrication systems as a means of reducing fuel consumption and lowering GHG emissions.
The deal will see Shell International Trading and Shipping Co Ltd and Silverstream develop a close working relationship to design, engineer, procure, and execute the Silverstream System.
The new framework will enable Shell to expedite installing the air lubrication technology in its LNG carrier fleet. Initially covering the next three years, the framework will ultimately reduce contract lead times and the total cost of ownership for vessel operators.
The co-operation between Shell and Silverstream Technologies follows in the wake of the delivery of the Maran Gas Andros, the first LNG carrier fitted with an air lubrication system. Built by South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME), Maran Gas Andros uses Daewoo’s air lubrication system (ALS). Maran Gas is expected to fit all of its LNG newbuilds with the DSME ALS.
The agreement between Shell and Silverstream Technologies indicates that ALS technology is gaining momentum and credibility as a fuel and emissions savings tool for LNG carriers.
Since 2014, Silverstream and Shell have collaborated on a number of vessel performance studies and sea trials to evaluate and verify the fuel savings potential of the Silverstream System.
Based on in-operation trials, Silverstream Technologies said its system reduces fuel consumption and associated GHG emissions by between 5 - 10%, depending on the vessel’s operational profile.
Silverstream Technologies chief executive Noah Silberschmidt said, “Shell has been a longstanding and important partner for our organisation, and strengthening this relationship will help to drive clean technology uptake within a crucial market segment.
“That is why signing this framework agreement today makes sense. Given the rate of change within our industry, we hope that this will prove to the sector that retrofitted clean technologies such as the Silverstream System are easy to procure and execute and should form an integral part of an overall GHG emissions reduction strategy for existing vessels and fleets.”
The Silverstream System reduces fuel consumption and associated emissions by creating a carpet of microbubbles that coat the entire flat bottom of the vessel. This ‘microbubble carpet’ reduces frictional resistance between the ship’s hull and the water. The technology works in all maritime conditions, is not weather dependent, and does not constrain or negatively impact the normal operational profile of the vessel.
