Clean Power For Italian Cruise Ships

MAN Diesel & Turbo consortium also features Alfa Laval’s PureSOx wet scrubbing system

Posted on June 17, 2013

MAN Diesel & Turbo will supply eight engines for the diesel-electric propulsion of two cruise ship newbuildings to cruise ship builder Fincantieri Cantieri Navali Italiani S.p.A.                

Each cruise ship will be powered by two MAN 9L32/44CR and two MAN 12V32/44CR engines, providing a combined output of 23 MW in a diesel-electric propulsion arrangement. The engines will operate with MAN’s common-rail injection system, suitable for both heavy fuel oil and distillate fuels. The company said this technology, which has been developed in-house and fully optimized for its engines, provides superior performance in terms of fuel consumption and smoke emissions, especially at part-load.

The company is delivering the engines in cooperation with Alfa Laval, which will supply accompanying exhaust-gas-treatment systems (PureSOx) for sulfur-oxide removal.

MAN said that by combining its efficiency-leading 32/44CR engines with the PureSOx exhaust-gas-treatment system, these super-luxury cruise vessels can fulfill the increasingly stringent global requirements for permissible sulfur-oxide emissions in the most economical manner possible. This especially applies to the demanding limit of 0.1% sulfur fuel equivalent in Emission Controlled Areas (ECAs), the company said.

Each newbuilding weighs in at 43 360 gross tonnes, has a length of 227.2 m, and a width of 28.8 m.

The two new vessels are bound for Viking Ocean Cruises, sister company of Viking River Cruises. Delivery to the ship owner is scheduled for early 2015 and early 2016, respectively.
