MAN Diesel & Turbo has secured a contract from Italian shipbuilder Fincantieri to deliver eight engines for the diesel-electric propulsion of two cruise ship newbuildings.
The company is supplying the engines in cooperation with Alfa Laval, which is delivering exhaust gas treatment systems (PureSOx) for sulphur oxide removal on the two new ships being built for Viking Ocean Cruises.
Each cruise ship will be equipped with a diesel-electric propulsion system powered by two 9L32/44CR and two 12V32/44CR engines, providing a combined output of 23,520 kW.
MAN’s common rail injection system will help the engines operate on both heavy fuel oil and distillate fuels.
According to MAN, the common rail technology will offer improved performance in terms of fuel consumption and smoke emissions, especially at part-load.
MAN Diesel & Turbo head of cruise & ferry sales Sokrates Tolgos said by combining the company’s 32/44CR engines with the PureSOx exhaust-gas-treatment system, the cruise vessels can fulfil the stringent global requirements for permissible sulphur-oxide emissions in an economical manner.
"This especially applies to the demanding limit of 0.1% sulphur fuel equivalent in emission controlled areas," Tolgos said.
Alfa Laval’s PureSOx system removes over 98% of sulphur oxides from exhaust gas.
Due to the strict space requirements on cruise ships, the more compact ‘multiple inlet’ PureSOx system design has been selected so the exhaust gas from each engine pair is cleaned in a single PureSOx system.
Each of the new cruise ships can carry 936 passengers with a crew to passenger ratio of approximately 1:2.
The two new cruise ships are scheduled to be delivered in early 2015 and early 2016 respectively.
In December 2012, Viking Ocean Cruises signed a Memorandum of Understanding for the construction of two cruise ships with an option for two more ships.
