Norwegian Spirit of sister company Norwegian Cruise Line was installed with Promas Lite in 2011. The efficiency gains and fuel-saving benefits from the first upgrade resulted in this subsequent order from Star Cruises, Rolls-Royce said.
Typical fuel savings for Promas Lite range from 5% to 15%, depending on the type of operation and the performance of the existing propeller. A cruise ship like SuperStar Virgo can expect to generate £800,000 annually in fuel savings and a corresponding carbon dioxide emission reduction of around 4,000 tonnes per year, Rolls-Royce said.
The estimated payback period is two years.
'Based on our previous positive experience with Rolls-Royce, we are confident that this upgrade will enable us to significantly reduce our fuel consumption and environmental impact,' said fleet captain Gustaf Gronberg, svp marine operations and newbuilding for Star Cruises.
