ASENAV ordered four MAN 6L21/31 Mk2 part-load optimized gensets for Antarctica21’s 94-meter passenger cruise-ship newbuilding.
Astilleros y Servicios Navales has ordered four MAN 6L21/31 Mk2 part-load optimized (PLO) gensets for Antarctica21’s 94-meter passenger cruise-ship newbuilding. The gensets will be installed on the Magellan Discoverer cruise ship, which is slightly larger than the previous Magellan Explorer vessel from 2019. These ships have the same engine type and PC6 polar-ice classification.
“We are delighted to reaffirm our partnership with MAN Energy Solutions Chile by selecting the 21/31 Mk2 PLO engine for our new polar vessel,” said Jaime Vásquez, President of Antarctica21. “This engine sets the standard for the lowest fuel consumption in its category. Our continued trust in MAN Energy Solutions after-sales service in Chile, renowned for its reliability and expertise, reinforces our decision.”
Each genset will be integrated with MAN Energy Solutions’ low-pressure selective catalytic reduction (LP-SCR) system that delivers NOx-reduction rates by up to 90%, satisfying the latest IMO environmental requirements. The engines will be built at MAN Energy’s facility in Aurangabad, India, where a compact RAMME PM (permanent magnet) alternator will also be integrated.
“The optimized MAN 21/31 Mk2 PLO GenSet improves fuel efficiency without additional costs and combines classic engine-design principles with innovative technology,” said Christian Kamm, Sales Manager Europe, Marine, MAN Augsburg. “The integrated SCR system will also ensure the protection of the pristine marine environments that this cruise ship will operate in.”
MAN Energy’s 21/31 Mk2 PLO engine maintains a reduced fuel-consumption (up to 9 g/kWh at 75% MCR) with increased times between overhauls. It also comes equipped with MAN’s safety and control system (SaCoSone). The Mk2 engine is also capable of burning conventional fuels such as HFO/LSFO, MDO, and MGO, complying with new ISO fuels regulations. Biodiesel fuels, like FAME and HVO-100, can be burned as well.
“We are very proud of this repeat order by Antarctica21 at ASENAV for MAN 21/31 engines. This displays great trust in MAN technology and further cements the solid foothold that our small-bore, four-stroke, medium-sized engines have established in the Chilean market,” said Gerardo Schneeberger, Head of Sales, Chile, MAN Energy Solutions. “The unique capabilities offered by PrimeServ Chile’s 24/7 service within all Chilean territories have also been key to winning this order.”
The PLO engine is designed as methanol-ready with an approval in principle from the DNV classification society. The approval confirms a retrofit to methanol operation as a green fuel at a later date, should it be required. MAN’s 21/31 engine, originally designed in 2000/2001 to provide a compact and robust engine, is characterized by easy installation and maintenance. Currently, between ordered and delivered engines, the 21/31 has accumulated sales of 2,750 units.
