The Air Lubrication System (ALS) chosen for the CHEK Project is supplied by London-based Silverstream Technologies. Silverstream’s market-leading ALS, the Silverstream® System, is a proven energy efficiency technology which fundamentally changes the interaction between water and a vessel, shearing air from air release units (ARUs) in the hull to create a carpet of microbubbles that coats the full flat bottom of a vessel.
Independent third parties including Lloyd’s Register, HSVA and the University of Southampton have verified that the Silverstream® System generates an average 5-10% net fuel and emissions saving, depending on vessel type. Silverstream’s customers include MSC, Shell, Carnival, Maersk, Grimaldi, Vale, ADNOC L&S and many others.
The Silverstream® System is unique in that it is the only proven ALS that can be retrofitted in 10 days or less, as well as being applicable for newbuildings. It lasts the lifetime of the vessel, is complementary to and can be used in conjunction with other clean technologies, as in the case of the CHEK Project, and its return on investment is typically between two and five years.
The system is applicable to all of shipping’s major segments and is effective in all sea states. It is also fuel-agnostic, meaning it is well-suited to both existing and future fuels. This gives shipowners the assurance that they are investing in a lifecycle solution for vessel efficiency.
