Request A Demo

The new M 25 E has been designed to completely meet the ultimate customer requirements, providing the lowest cost of operation while maintaining the highest uptime in the industry. Since one engine standard typically does not fit all applications, different M 25 E configurations will be available to support various application-specific requirements. Based on the proven M 25 C, all versions have been extensively optimized for best fuel consumption and load acceptance, leading reliability and durability, and efficient Selective Catalytic Reduction (SCR) operation. The service and maintenance-friendly design, remote condition monitoring and diagnostic capabilities, as well as our unmatched global product support, respond to the industry's desire to lower operational costs and down times beyond today's standards.

Emissions

For IMO III emissions the MaK M 25 E is delivered with a Scheme A factory certified SCR solution and a factory EIAPP certificate, simplifying installation and commissiong work significantly. Caterpillar's SCR technology minimizes total cost of ownership by cutting the diesel and urea expenses by offering the lowest total fluid consumption at optimized engine and SCR life time.

Performance

5% more power, Leading load response

Fuel Efficiency

A typical offshore supply vessel operator can save up to $ 250,000 per year in fuel cost.The part load efficiency of one M 25 E can save up to 40 tons of fuel per year in a variable speed application (average 60% load). Low load variable speed capability can save 50– 60 tons per year versus constant speed applications (average 20–25% load).

Safety

Unmatched reliability based on the proven MaK M 25 C so you always get home safely, even in the worst conditions.

Higher Uptime equals More Revenue

Extended times between overhauls to reduce lay-days for maintenance.

Unique Solutions

Combined with propellers designed and optimized for vessels' normal cruise speed, the part load optimized M 25 E is developed for vessels where maximum engine power or propeller thrust is only required for a fraction of the operation time. Operational cost benefits are achieved by operating propellers and engines at best points of efficiency.

Onsite Product Support and Online Monitoring

The new Monitoring Alarm and Control System (MACS) from Caterpillar provides additional functionality regarding engine control, diagnostics, and remote monitoring, including the option to extend the features to engine related systems like SCR's (Selective Catalytic Reduction) where customers have elected to reduce NOx related taxes or harbor fees.
