Specialized expertise for your sector 

Safety first! The cruise industry involves with the highest standards of safety. Our engines contribute to the overall safety of your ship, its passengers, and its crew by means of reliable design and quality. 

Intelligent power for your business: MAN four-stroke engines for cruise ships

Once reserved for the wealthy, cruises are now affordable to many, and this segment is experiencing significant growth. Cruise lines are building spectacularly complex ships that operate all day, practically every day of the year. 


Passenger vessels typically sail in environmentally sensitive areas, so their engines must meet stringent emission regulations. At the same time, operating costs must be kept low to ensure the best possible economic result in an increasingly competitive environment.

Intelligent power for your business

MAN offers a wide range of highly efficient and reliable common rail engines for cruise ships. Common rail technology allows the independent setting of injection timing, duration, and pressure. This flexibility promotes the highest possible degree of freedom of optimization in fuel consumption, NOx and smoke emissions.

The growing awareness of the cruise industry's environmental impact together with ever more stringent emission regulations, especially in coastal areas, is an important factor in the design of new cruise ships.

The ships must also be economical to operate, so as to keep holiday prices attractive.

Today’s cruise ships must meet high demands for non-stop reliable, comfortable, and silent power generation onboard. MAN offers highly efficient and reliable common rail (CR) propulsion engines and GenSets, which – thanks to their fully electronic injection system – allow the highest possible degree of freedom of optimization in fuel consumption, reducing NOx, and smoke emissions while ensuring the utmost passenger comfort.

Exhaust after-treatment solutions

Asset-5Selective catalytic reduction (MAN SCR) is the most approved means for NOX reduction. Our system covers a broad range of engines and is designed for customization.

Respecting the environment

The International Maritime Organization sets limits for nitrogen oxide (NOX) emissions and the sulfur content of fuel. Our proven exhaust gas after-treatment systems easily meet these regulations, even in Emission Control Areas (ECA).

MAN SCR – selective catalytic reduction

NOX can be efficiently minimized by using selective catalytic reduction and exhaust gas recirculation. The MAN SCR exhaust after-treatment system provides an integrated and intelligent solution for our entire portfolio of medium-speed engines. With reliable operation and the highest performance, it serves as a standard solution to meet the IMO Tier III emission limits. Our system covers a broad range of engines and is designed for customization.
