Shell to retrofit Silverstream’s underwater technology

Free Read

UK-based Silverstream Technologies has signed a framework agreement to retrofit a number of Shell operated LNGCs with air lubrication systems to reduce fuel consumption and lower greenhouse gas 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.

It will enable Shell to expedite installing the air lubrication technology in its LNGC fleet. Initially covering the next three years, the agreement 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 ’Maran Gas Andros’, the first LNGC fitted with an air lubrication system.

Built by Daewoo Shipbuilding & Marine Engineering (DSME), ’Maran Gas Andros’ uses Daewoo’s air lubrication system (ALS). Maran Gas is expected to fit all of its LNGC newbuilds with the DSME ALS.

The latest agreement indicates that ALS technology is gaining momentum and credibility as a fuel and emissions savings tool for LNGCs.

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 claimed that its system reduces fuel consumption and associated greenhouse gas (GHG) emissions by between 5-10%, depending on the vessel’s operational profile.

Silverstream’s CEO, 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 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 company also recently signed a licence and co-operation agreement with Wärtsilä, which intends to fully integrate Silverstream’s ALS within its propulsion solutions.
