Diamond Princess retrofitted with Silverstream air lubrication system

The Silverstream system has been in operation on Diamond Princess since June 2017
Carnival Corp. & plc has successfully retrofited a Silverstream Technologies’ air lubrication system on Diamond Princess.

The Silverstream system has been in operation on the Princess Cruises' ship since June 2017, reducing fuel consumption and related CO2 emissions.

It recently completed its final contract trials, which demonstrated that the original performance expectations were exceeded with net efficiency improvements of over 5% at the design service speed, verified by Lloyd’s Register, said Silverstream Technologies.

It is delivering tangible reductions in fuel costs and emissions, attained through comprehensive sea-trialling and in-operation data analysis, notes the supplier.

'Sustainability is a top priority for Carnival Corporation', said Mike Kaczmarek, vp of corporate marine technology.

Setting clear goals on efficiency improvements

‘Our recent Sustainability Report, published in 2017, set clear goals for improving the efficiency of our fleet through overall operations and innovative solutions. Retrofitting Silverstream’s air lubrication technology on he Diamond Princess is another example of our ongoing efforts to leverage technology to reduce fuel consumption and emissions,’ Kaczmarek added.

Noah Silberschmidt, ceo, Silverstream Technologies said: ‘The installation of the Silverstream System on Diamond Princess once again demonstrates the very real demand for proven clean technologies that are cost-effective, easy to implement and operate, and deliver the efficiency benefits that are claimed.’

He added, data from installations has shown that noise and vibration emissions are also reduced.
