The Rolls-Royce Promas Lite integrated rudder propeller system is to be fitted to five ships of the Grimaldi Group, of Italy.
Grimaldi Lines will upgrade the five 56,842gt Grande-class pure car truck carriers Grande Nigeria, Grande Amburgo, Grande San Paolo, Grande Francia and Grande Buenos Aries with the fuel-saving technology.
Paolo Satariano, of the Grimaldi group, said: “The retrofitting of the Promas Lite system to our vessels last year proved a huge success. Rolling out the system to other vessel types in the Group was an easy decision.”
The upgrade consists of three main components: a bulb which is attached to the forward edge of the rudder; a hubcap which is bolted to the rear of the propeller; and a set of redesigned propeller blades. Each Promas Lite system is tailored to each vessel’s specific requirement.
