A newbuild Carnival Corporation Excel-class cruise ship, currently known as hull S717, is to be fitted with an air lubrication technology system from Silverstream Technologies following the agreement of a contract with Meyer Werft Shipyard.
The Silverstream System uses a series of air release units (ARUs) in the flat bottom of a vessel to generate a rigid carpet of microbubbles that travel the full length of the hull. The technology will be installed during S717’s construction, with Meyer Werft manufacturing the ARUs to Silverstream specifications.
Once installed, the system is expected to generate net fuel and emissions savings of more than 5%. The 344m vessel will be operated by Carnival Cruise Line when it is delivered in 2023. Like other vessels in its class, it will be powered by Liquefied Natural Gas (LNG).
The companies already have an existing relationship in air lubrication installation, starting in 2017 with the installation of the technology on the Princess Cruises vessel Diamond Princess.
“At Carnival, we are committed to building the cruise industry’s most efficient and sophisticated ships. The addition of the Silverstream System on Carnival Cruise Line’s third Excel-class ship will ensure that this vision continues to become a reality,” said Ben Clement, Senior Vice President, Newbuilds, Refurbishments & Product Innovation, Carnival Cruise Line.
“Following the impressive fuel and emission savings on Diamond Princess, and subsequent orders of the system, we value our relationship with Silverstream and are excited to explore more opportunities to champion clean technologies in the future.”
