Silverstream Technologies has signed an agreement with Carnival Corporation to install the company’s air lubrication system on another two cruise ships.

These will be the third and fourth newbuild Excel-class vessels to be fitted with the system, Silverstream said in a press release.

Noah Silberschmidt, Founder and CEO of Silverstream Technologies, said: “Cruise operators have consistently been frontrunners in embracing advanced technologies across their fleets.”

“Since 2016, we have proudly partnered with Carnival Corporation, the industry’s largest operator, to support their decarbonization journey with our proven air lubrication technology. The need of the hour is to raise decarbonization ambitions, and we are committed to building large-scale partnerships that advance sustainability across the entire sector,” added Silberschmidt.

Carnival’s Chief Maritime Officer, Vice Admiral (Ret.) William R. Burke, said: “Silverstream’s ability to deliver proven, verified GHG and fuel cost savings sets them apart in a crowded marketplace.”

“Our continued partnership has thrived thanks to our shared commitment to advancing sustainability in the maritime sector. As we work towards net zero by 2050, we look forward to many more years of collaboration, driving energy efficiency, reducing fuel consumption and cutting emissions throughout our fleet,” added Burke.

According to the press release, the LNG-powered newbuild vessels will integrate Silverstream’s technology onboard, unlocking net fuel savings potential and paving the way for the next generation of low-emission passenger vessels.

Previously, the system delivered approximately 5 percent net fuel and emissions savings onboard the Diamond Princess.

The two newbuilds, scheduled for delivery in 2027 and 2028, will result in a total of 16 vessels in Carnival Corporation’s fleet with the Silverstream System.
