MAN Diesel & Turbo supplying engines for two cruise ships

Posted on June 14, 2013

MAN Diesel & Turbo will supply eight engines for the diesel-electric propulsion of two cruise ship newbuildings to Fincantieri Cantieri Navali Italiani S.p.A. MAN is delivering the engines in cooperation with Alfa Laval, who will supply accompanying exhaust-gas-treatment systems (PureSOx) to remove sulfur oxide.

Each cruise ship will be powered by 2 × MAN 9L32/44CR + 2 × MAN 12V32/44CR engines, providing a combined output of 23 520 kW in a diesel-electric propulsion arrangement. The engines will operate with MAN Diesel & Turbo’s common-rail injection system, suitable for heavy fuel oil and distillate fuels.

The two new vessels are bound for Viking Ocean Cruises, sister company of Viking River Cruises. With a total passenger capacity of 936 and a 1:2 crew-to-passenger ratio, the ships will meet the demand for small, super-luxury vessels. Delivery of the two newbuildings to the ship owner is scheduled for early 2015 and early 2016, respectively.

Alfa Laval’s PureSOx system removes over 98% of sulfur oxides from a ship’s exhaust gas through washing it with seawater (open-loop system), or freshwater (closed-loop system), or a combination of both (hybrid system). This enables vessels to comply with International Maritime Organization (IMO) regulations by using heavy fuel oil instead of low-sulfur marine gas-oil.
